Octal transceiver with direction pin, 30 series termination
resistors; 5 V tolerant input/output; 3-state
Rev. 5 — 4 November 2011
Product data sheet
1. General description
The 74LVC2245A is a octal transceiver featuring non-inverting 3-state bus compatible
outputs in both send and receive directions.
A send/receive (DIR) input controls direction, and an output enable (OE) input makes
easy cascading possible. Pin OE controls the outputs so that the buses are effectively
It is a high-performance, low-power, low-voltage, Si-gate CMOS device and superior to
most advanced CMOS compatible TTL families.
The device is designed with 30 series termination resistors in both HIGH and LOW
output stages to reduce line noise.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be
applied to the outputs. These features allow the use of these devices as translators in
mixed 3.3 V and 5 V applications.
