D Data Flow-Through Pinout (All Inputs on

Opposite Side From Outputs)

description/ordering information

These octal buffers and line drivers are designed

to have the performance of the popular ’HC240

series devices and to offer a pinout with inputs and

outputs on opposite sides of the package. This

arrangement greatly facilitates printed circuit

board layout.

The 3-state control gate is a 2-input NOR. If either

output-enable (OE1

or OE2) input is high, all eight

outputs are in the high-impedance state. The

’HCT541 devices provide true data at the outputs.
