74AHC240; 74AHCT240

Octal buffer/line driver; inverting; 3-state

Rev. 4 — 25 September 2013

Product data sheet

1. General description

The 74AHC240 and 74AHCT240 are 8-bit inverting buffer/line drivers with 3-state outputs.

These devices can be used as two 4-bit buffers or one 8-bit buffer. They feature two

output enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH on

nOE causes the outputs to assume a high-impedance OFF-state. Inputs are over voltage

tolerant. This feature allows the use of these devices as translators in mixed voltage

environments.

2. Features and benefits

 Balanced propagation delays

 All inputs have a Schmitt-trigger action

 Inputs accepts voltages higher than V_CC

 For 74AHC240 only: operates with CMOS input levels

 For 74AHCT240 only: operates with TTL input levels

 ESD protection:

 HBM JESD22-A114F exceeds 2000 V

 CDM JESD22-C101D exceeds 1000 V

 Multiple package options

 Specified from 40 C to +85 C and from 40 C to +125 C
