74LVC2245ABQ

Octal transceiver with direction pin

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 isolated.

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 Ω 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.
