UM3202 2-Bit Bidirectional Voltage-Level Translator for Open-Drain and Push-Pull Application UM3202Q DFN8 1.70×1.35 UM3202A QFN10 1.8×1.4 UM3202H CSP8 1.9×0.9 General Description The UM3202Q/3202A/3202H is ±15kV dual channel ESD-protected level translator provide the level shifting necessary to allow data transfer in a multi-voltage system. Externally applied voltages, VCCB and VCCA, set the logic levels on either side of the device. A low-voltage logic signal present on the VCCA side of the device appears as a high-voltage logic signal on the VCCB side of the device, and vice-versa. The UM3202Q/3202A/3202H bidirectional level translator utilizes a transmission-gate based design to allow data translation in either direction (VCCA↔VCCB) on any single data line. The UM3202Q/3202A/3202H accepts VCCA from +1.65V to +3.6V and VCCB from +2.3V to +5.5V, making it ideal for data transfer between low-voltage ASICs / PLDs and higher voltage systems. The UM3202Q/3202A/3202H enters a three-state output mode to reduce supply current when output enable (OE) is low. The UM3202Q/3202A/3202H is designed so that the OE input circuit is supplied by VCCA. ±15kV ESD protection on the VCCB side for greater protection in applications that route signals externally. The UM3202Q is a dual level translator available in DFN8 1.70×1.35, the UM3202A is a dual level translator available in QFN10 1.8×1.4, and the UM3202H is a dual level translator available in CSP8 1.9×0.9 package.

The UM3202Q/3202A/3202H is ideal for use in application where an open-drain driver is connected to the data I/Os. The UM3202Q/3202A/3202H can also be used in applications where a push-pull driver is connected to the data I/Os, but the UM3302 might be a better option for such push-pull applications. Block Diagram The UM3202Q/3202A/3202H (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. Each A-port I/O has an internal 10kΩ pullup resistor to VCCA, and each B-port I/O has an internal 10-kΩ pullup resistor to VCCB. During a rising edge, the one-shot turns on the PMOS transistors (PU1, PU2) for a short duration, which speeds up the low-to-high transition. VCCB VCCA PU1 ONESHORT BLOCK ONESHORT BLOCK PU2 GATE BIAS I/O VA_ I/O VB_ N Figure 1 Block Diagram of UM3202Q/3202A/3202H I/O Cell Input Driver Requirements The fall time (tfA, tfB) of a signal depends on the output impedance of the external device driving the data I/Os of the UM3202Q/3202A/3202H. Similarly, the tPHL and the maximum date rates also depend on the output impedance of the external driver. The values for tfA, tfB, tPHL, and the maximum date rates in the data sheet assume that the output impedance of the external driver is less than 50Ω. Power Up During operation, ensure that VCCA≤VCCB at all times. During power-up sequencing, VCCA≥ VCCB does not damage the device, so any power supply can be ramped up first. Enable and Disable The UM3202Q/3202A/3202H has an OE input that is used to disable the device by setting OE = low, which places all I/Os in the high-impedance (Hi-Z) state. The disable time (tdis) indicates the delay between the time 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. ________________________________________________________________________ http://www.union-ic.com Rev.08 Dec.2014 9/14 UM3202 Pullup or Pulldown Resistors on I/O Lines Each A-port I/O has an internal 10-kΩ pullup resistor to VCCA, and each B-port I/O has an internal 10-kΩ pullup resistor to VCCB. If a smaller value of pullup resistor is required, an external resistor must be added from the I/O to VCCA or VCCB (in parallel with the internal 10-kΩ resistor).
