74AHC245; 74AHCT245

Octal bus transceiver; 3-state

Rev. 03 — 25 September 2007

Product data sheet

1. General description

The 74AHC/AHCT245 is a high-speed Si-gate CMOS device.

The 74AHC/AHCT245 is an octal transceiver featuring non-inverting 3-state bus

compatible outputs in both send and receive directions.

The 74AHC245/74AHCT245 features an Output Enable (OE) input for easy cascading

and a send/receive (DIR) input for direction control.

OE controls the outputs so that the buses are effectively isolated.

2. Features

Balanced propagation delays

All inputs have a Schmitt-trigger action

Inputs accepts voltages higher than V

For 74AHC245 only: operates with CMOS input levels

For 74AHCT245 only: operates with TTL input levels

ESD protection:

HBM JESD22-A114E exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

CDM JESD22-C101C exceeds 1000 V
