Product specification

74LVC241A

Octal buffer/line driver with 5-volt tolerant

inputs/outputs (3-State)

1998 May 20

853-2005 19419

FEATURES

• 5-Volt tolerant inputs/outputs, for interfacing with 5-volt logic.

• Supply voltage range of 1.2 to 3.6 V

• In accordance with JEDEC standard no. 8-1A

• CMOS lower power consumption

• Direct interface with TTL levels

• High impedance when V

CC = 0 V

DESCRIPTION

The 74LVC241A is a high-performance, low-power, low-voltage,

Si-gate CMOS device and superior to most advanced CMOS

compatible TTL families.

Inputs can be driven from either 3.3 V or 5 V devices. In 3-State

operation, outputs can handle 5 V. This feature allows the use of

these devices as translators in a mixed 3.3 V/5 V environment.

The 74LVC241A 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. Schmitt-trigger action at all inputs makes the circuit

highly tolerant for slower input rise and fall times.
