Ordering Information

Description

Die Dimensions in µm (mils)

The 54HC240 is produced on a 2.5µm 5V CMOS process

combining high speed LSTTL performance with CMOS low

power. The device can be used as two 4-bit buffers or one

8-bit buffer & features inverting inputs with two output

enables, each controlling four of the 3-state outputs. The

device improves performance & density in clock drivers, 3-

state memory address drivers & bus orientated transmitters

and receivers. Device inputs are compatible with standard

CMOS outputs; with pull-up resistors, they are compatible

with LSTTL outputs. All inputs are equipped with protection

circuits against static discharge & transient excess voltage.
