description/ordering information

These octal buffers and line drivers feature the

performance of the ’HC240 devices and a pinout

with inputs and outputs on opposite sides of the

package. This arrangement greatly facilitates

printed circuit board layout.

The 3-state outputs are controlled by a two-input

NOR gate. If either output-enable (OE1

or OE2)

input is high, all eight outputs are in the

high-impedance state. The ’HC541 devices

provide true data at the outputs.
