General Description

The UM3204 is ±15kV quad channel ESD-protected level translator provide the level shifting necessary to allow data transfer in a multi-voltage system. Externally applied voltages, V V

, set the logic levels on either side of the device. A low-voltage logic signal present on the

CCA

V

side of the device appears as a high-voltage logic signal on the V

CCA

side of the device, and

CCB

and

vice-versa. The UM3204 bidirectional level translator utilizes a transmission-gate based design to allow data translation in either direction (V accepts V

from +1.65V to +3.6V and V

CCA

CCA↔VCCB

from +2.3V to +5.5V, making it ideal for data

CCB

) on any single data line. The UM3204

transfer between low-voltage ASICs / PLDs and higher voltage systems. The UM3204 enters a three-state output mode to reduce supply current when output enable (OE) is low. The UM3204 is designed so that the OE input circuit is supplied by V protection on the V

side for greater protection in applications that route signals externally. The

UM3204

Applications Information

The UM3204 can be used in level-translation applications for interfacing devices or systems operating at different interface voltages with one another. The UM3204 is ideal for use in application where an open-drain driver is connected to the data I/Os. The UM3204 can also be used in applications where a push-pull driver is connected to the data I/Os, but the UM3304 might be a better option for such push-pull applications.

Block Diagram

The UM3204 (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 10-kΩ pull-up resistor to V 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.

, and each B-port I/O has an internal 10-kΩ pull-up resistor to V

.

Figure 1 Block Diagram of UM3204 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 UM3204. Similarly, the t depend on the output impedance of the external driver. The values for tfA, tfB, t

and the maximum date rates also

PHL

, 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 V

CCA≤VCCB

at all times. During power-up sequencing, V

CCA

≥ V

CCB

does not damage the device, so any power supply can be ramped up first.

Enable and Disable

The UM3204 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.
