General description

The 74LVT245B is a high-performance BiCMOS product designed for VCC operation at 3.3 V.

Features

■ 3-state buffers

■ Octal bidirectional bus interface

■ Input and output interface capability to systems at 5 V supply

■ TTL input and output switching levels

■ Output capability: +64 mA/−32 mA
