Description

The FXLA0104 is a configurable dual -voltage supply translator for both uni -directional and bi -directional voltage translation betw een tw o logic levels. The device allow s translation betw een voltages as high as 3.6 V to as low as 1.1 V. The A port tracks the V CCA level and the B port tracks the V CCB level. This allow s for bi-directional voltage translation over a variety of voltage levels: The device remains in three- state as long as either V CC=0V, allow ing either V CC to be pow ered up first. Internal pow er-dow n control circuits place the device in 3-state if either V CC is removed. The OE input, w hen LOW, disables both the A and B ports by placing them in a 3- state condition. The OE input is supplied by V CCA. The FXLA0104 supports bi -directional translation w ithout the need for a direction control pin. The tw o 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.

www.onsemi.com FXLA0104 — Low-Voltage Dual-Supply 4-Bit Voltage Translator Power-Up/Power-Down Sequence FXL translators offer an advantage in that either V CC may be pow ered up first. This benefit derives from the chip design. When either V CC is at 0 V, outputs are in a high-impedance state. The control input ( OE) is designed to track the V CCA supply. The recommended pow er -up sequence is: 1. Apply pow er to the first VCC. 2. Apply pow er to the second VCC. 3. Drive the OE input HIGH to enable the device. The recommended pow er -dow n sequence is: 1. Drive OE input LOW to disable the device. 2. Remove pow er from either VCC. 3. Remove pow er from other VCC. Pull-Up/Pull-Down Resistors Do not use pull -up or pull -dow n resistors . This device has bus -hold circuits: pull -up or pull -dow n resistors are not recommended because they interfere w ith the output state. T he current through these resistors may exceed the hold drive, I I(HOLD) and/or I I(OD) bus-hold currents, resulting in data transition and/or auto- direction sensing failures . The bus -hold feature eliminates the need for extra resistors.

www.onsemi.com FXLA0104 — Low-Voltage Dual-Supply 4-Bit Voltage Translator I/O Architecture Benefit The FXLA0104 I/O architecture benefits the end user, beyond level translation, in the follow ing three w ays: Auto Direction w ithout an external direction pin. Drive Capacitive Loads . Automatically shifts to a higher current drive mode only during “Dynamic Mode” or HL / LH transitions. Lower Power Consumption . Automatically shifts to low-pow er mode during “Static Mode” (no transitions), low ering pow er consumption. The FXLA0104 does not require a direction pin. Instead, the I/O architecture detects input transitions on both side and automatically transfers the data to the corresponding output. For example, for a given channel, if both A and B side are at a static LOW, the direction has been established as A  B, and a LH transition occurs on the B port; the FXLA0104 internal I/O architecture automatically changes direction from A  B to B  A. During HL / LH transitions, or “Dynamic Mode,” a strong output driver drives the output channel in parallel w ith a w eak output driver. After a typical delay of approximately 10 ns – 50 ns, the strong driver is turned off, leaving the w eak driver enabled for holding the logic state of the channel. This w eak driver is called the “bus hold.” “Static Mode” is w hen only the bus hold drives the channel. The bus hold can be over ridden in the event of a direction change. The strong driver allow s the FXLA0104 to quickly charge and discharge capacitive transmission lines during dynamic mode. Static mode conserves pow er, w here I CC is typically < 5 µA. Bus Hold Minimum Drive Current Specifies the minimum amount of current the bus hold driver can source/sink. The bus hold minimum drive current ( II HOLD) is V CC dependent and guaranteed in the DC E lectrical tables. The intent is to maintain a valid output state in a static mode, but that can be overridden w hen an input data transition occurs. Bus Hold Input Overdrive Drive Current Specifies the minimum amount of current required (by an external device) to overdrive the bus hold in the event of a direction change. The bus hold overdrive (II ODH, IIODL) is V CC dependent and guaranteed in the DC Electrical tables. Dynamic Output Current The strength of the output driver during LH / HL transitions is referenced on page 8, Dynamic Output Electrical Characteristics, I OHD, and IOLD.
