3.3 V octal transceiver with direction pin (3-state)
Rev. 02 — 8 May 2008
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.
2. Features
I 3-state buffers
I Octal bidirectional bus interface
I Input and output interface capability to systems at 5 V supply
I TTL input and output switching levels
