Product data sheet
1. General description
The 74LVT245B is a high-performance BiCMOS product designed for V
CC
operation at
3.3 V.
This device is an octal transceiver featuring non-inverting 3-state bus compatible outputs
in both send and receive directions. The control function implementation minimizes
external timing requirements. The device features an output enable (OE) input for easy
cascading and a direction (DIR) input for direction control.
