74AC541 • 74ACT541

Octal Buffer/Line Driver with 3-STATE Outputs

General Description

The 74AC541 and 74ACT541 are octal buffer/line drivers

designed to be employed as memory and address drivers,

clock drivers and bus oriented transmitter/receivers.

These devices are similar in function to the 74AC244 and

74ACTC244 while providing flow-through architecture

(inputs on opposite side from outputs). This pinout arrange-

ment makes these devices especially useful as an output

port for microprocessors, allowing ease of layout and

greater PC board density.

Features

s 3-STATE outputs

s Inputs and outputs opposite side of package, allowing

easier interface to microprocessors

s Output source/sink 24 mA

s 74AC541 is a non-inverting option of the 74AC540

s 74ACT541 has TTL-compatible inputs

Ordering Code:

Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.

Pb-Free package per JEDED J-STD-020B.

Note 1: “_NL” indicates Pb-Free package (per JEDEC J-STD-020B). Device available in Tape and Reel only.
