http://www.union-ic.com Rev.07 Sep.2013 8 / 1 3 UM3302H/UM3302Q Applications Information UM3302 ESD protected level translator provides leve l shifting necessary to allow data transfer in a multi-voltage system. Externally applied voltages, V CCA and V CCB set the logic levels on either side of device. A low voltage signal present on V CCA side of the device appears as a high voltage logic signal on the VCCB side of the device, and vice-versa. Block Diagram The UM3302 (block diagram see Figure 1) does not require a direction-control signal to control the direction of data flow from A to B or from B to A. In a dc state, the output drivers of the UM3302 can maintain a high or low, but are designed to be weak, so that they can be overdriven by an external driver when data on the bus starts flowing the opposite direction. The output one shot detects rising or falling edges on the A or B ports. During a rising edge, the one shot turns on the PMOS transistors (T1, T3) for a short duration, which speeds up the low-to-high transition. Similarly, during a falling edge, the one shot turns on the NMOS transistors (T2, T4) for a short duration, which speeds up the high-to-low transition. Figure 1 Block Diagram of UM3302 I/O Cell
http://www.union-ic.com Rev.07 Sep.2013 9 / 1 3 UM3302H/UM3302Q Input Driver Requirements Typical IIN vs VIN characteristics of the UM3302 are shown in Figure 2. For proper operation, the device driving the data I/Os of the UM3302 must have drive strength of at least ±2 mA. A: VT is the input threshold voltage of the UM3302 (typical VCCI/2) B: VD is the supply voltage of the external driver. Figure 2 Typical IIN vs VIN Curve Power Up During operation, ensure that V CCA≤VCCB at all times. During power-up sequencing, V CCA≥ VCCB does not damage the device, so any power s upply can be ramped up first. The UM3302 has circuitry that disables all output ports when either VCC is switched off (VCCA/B = 0 V). Enable and Disable The UM3302 has an OE input that is used to di sable the device by setting OE = low, which places all I/Os in the high-impedance (Hi-Z) state. Th e disable time (tdis) indicates the delay between when OE goes low and when the outputs actually get disabled (Hi-Z). The enable time (ten) indicates the amount of time the user must allow for the one-shot circuitry to become operational after OE is taken high. Pullup or Pulldown Resistors on I/O Lines The UM3302 is designed to drive capacitive loads of up to 50pF. The output drivers of the UM3302H have low dc drive strength. If pullup or pulldown resistors are connected externally to the data I/Os, their values must be kept higher than 50k Ω to ensure that they do not contend with the output drivers of the UM3302. For the same reason, the UM3302 should not be used in applications such as I 2C or 1-Wire where an open-drain driver is connected on the bidirectional data I/O.
