Dual-Bit Dual-Supply Bus Transceiver with Configurable Voltage Translation and 3-State Outputs

Dual-Bit Dual-Supply Bus Transceiver with Configurable Voltage Translation and 3-State Outputs - SN74AVC2T45
 

Description

This 2-bit non-inverting bus transceiver uses two separate configurable power-supply rails. The A ports are designed to track VCCA and accepts any supply voltage from 1.2 V to 3.6 V. The B ports are designed to track VCCB and accepts any supply voltage from 1.2 V to 3.6 V. This allows for universal low-voltage bidirectional translation and level-shifting between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.

The SN74AVC2T45 is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR pin) input activate either the B-port outputs or the A-port outputs. The device transmits data from the A bus to the B bus when the B-port outputs are activated and from the B bus to the A bus when the A-port outputs are activated. The input circuitry on both A and B ports always is active and must have a logic HIGH or LOW level applied to prevent excess leakage current on the internal CMOS structure.
