74LVT245B
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 VCC 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
I Output capability: +64 mA/32 mA
I Latch-up protection exceeds 500 mA per JEDEC Std 17
I ESD protection:
N HBM JESD22-A114E exceeds 2000 V
N MM JESD22-A115-A exceeds 200 V
I Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs
I Live insertion/extraction permitted
I Power-up 3-state
I No bus current loading when output is tied to 5 V bus
