74LVT245

3.3 V octal transceiver with direction pin (3-state)

Rev. 4 — 24 December 2013

Product data sheet

1. General description

The 74LVT245 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. It features an output enable (OE) input for easy cascading

and a direction (DIR) input for direction control.

2. Features and benefits

 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

 Latch-up protection exceeds 500 mA per JESD78 class II level A

 ESD protection:

 HBM JESD22-A114E exceeds 2000 V

 MM JESD22-A115-A exceeds 200 V

 Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs

 Live insertion/extraction permitted

 Power-up 3-state

 No bus current loading when output is tied to 5 V bus
