 Description

The DIA7B108 is a 8-bit bidirectional voltage level

translator with output enable (OE) pin. The device

uses two separate configurable power-supply rails.

The A port is designed to track VCCA and the VCCA

supplies voltage from 1.08 V to 3.6 V, so DIA7B108

meets the requirement of low voltage system

application. The B port is designed to track VCCB and

VCCB supplies voltage from 1.65 V to 5.5 V. VCCA

should not exceed VCCB. This allows for universal

low-voltage bidirectional translation between any of

the 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V voltage

system.

The DIA7B108 has an output enable pin which

control the output status. When the OE input is low,

all I/Os are placed in the high-impedance state. To

ensure the high-impedance state during power up or

power down, OE should be connected to GND via a

pull-down resistor. Pins of A port and OE are

referenced to VCCA and pins of B port are referenced

to VCCB.

This device is fully specified for partial power-down

applications using IOFF. The IOFF circuitry disables the

output, preventing the damaging backflow current

through the device when it is powered down.

The DIA7B108 is available in TSSOP-20 package. It

is specified over ambient temperature range of -40°C

to 125°C, which meets the requirements of

automotive applications.
