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 I_CC and I_OZ reduced by 50%
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
