description/ordering information
GND 10
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.
