Ordering Information
Die Dimensions in µm (mils)
The 74HC240 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.
