Features
Bi-directional interface between two levels from 1.1V to 3.6V. Fully configurable: Inputs and outputs track V CC level. Non-preferential power-up; either V CC may be powered-up first. Outputs remain in 3-state until active V CC level is reached. Outputs switch to 3-state if either V CC is at GND. Power off protection Bushold on data inputs eliminates the need for pull-up or pull-down resistors Control input (OE) is referenced to V CCA voltage. Packaged in 8-terminal leadless MicroPak (1.6mm x 1.6mm) Direction control not needed. 100 Mbps throughput when translating between 1.8V and 2.5V. ESD protection exceeds: – 15kV HBM (B port I/O to GND) (per JESD22-A114 & Mil Std 883e 3015.7) – 8kV HBM (A port I/O to GND) (per JESD22-A114 & Mil Std 883e 3015.7) – 2kV CDM (per ESD STM 5.3) General Description The FXLA102 is a configurable dual-voltage-supply translator designed for both uni-directional and bi- directional voltage translation between two logic levels. The device allows translation between voltages as high as 3.6V to as low as 1.1V. The A port tracks the V CCA level, and the B port tracks the V CCB level. This allows for bi-directional voltage translation over a variety of The device remains in 3-state until both VCCs reach active levels, allowing either V CC to be powered-up first. Internal power down control circuits place the device in 3-state if either V CC is removed. The OE input, when high, disables both the A and B ports by placing them in a 3-state condition. The OE input is supplied by V CCA The FXLA102 supports bi-directional translation without the need for a direction control pin. The two ports of the device have auto-direction sense capability. Either port may sense an input signal and transfer it as an output signal to the other port.

This benefit derives from the chip design. When either V CC is at 0 volts, outputs are in a high-impedance state. The control input (OE ) is designed to track the V CCA supply. A pull-up resistor tying OE to V CCA should be used to ensure that bus contention, excessive currents, or oscillations do not occur during power-up/power-down. The size of the pull-up resistor is based upon the current-sinking capability of the device driving the OE pin. The recommended power-up sequence is the following: 1. Apply power to the first V CC 2. Apply power to the second V CC 3. Drive the OE input LOW to enable the device. The recommended power-down sequence is the following: 1. Drive OE input HIGH to disable the device. 2. Remove power from either V CC 3. Remove power from other V CC Number Name Description CCA A Side Power Supply 2, 3 A , A A Side Inputs or 3-State Outputs

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Note: 1. I O Absolute Maximum Rating must be observed. Recommended Operating Conditions (2) The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not recommend exceeding them or designing to absolute maximum ratings. Note: 2. All unused inputs and I/O pins must be held at V CCI or GND.

ANTI-COUNTERFEITING POLICY Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com, under Sales Support. Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technicala nd product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
