(TOP VIEW)
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.
