General description

The 74LVC240A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families.

Inputs can be driven from either 3.3 or 5 V devices. In 3-state operation, outputs can handle 5 V. These features allow the use of these devices as translators in a mixed 3.3 and 5 V environment.

The 74LVC240A is an octal non-inverting buffer/line driver with 3-state outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Schmitt-trigger action at all inputs makes the circuit highly tolerant for slower input rise and fall times.

The 74LVC240A is functionally identical to the 74LVC244A, which has non-inverting outputs.

Features

5 V tolerant inputs/outputs for interfacing with 5 V logic
Supply voltage range from 1.2 to 3.6 V
CMOS low power consumption
Direct interface with TTL levels
Inputs accept voltages up to 5.5 V
High-impedance when V_CC =0 V
Complies with JEDEC standard no. 8-1A
ESD protection:

Specified from -40 to +85 Cel and -40 to +125 Cel.
