Features:

Ordering Information

The 74AC240 is produced on a 1.5µm 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 is designed to improve performance & density in

clock drivers, 3-state memory address drivers & bus

orientated transmitters and receivers. Inputs accept

standard CMOS outputs or LSTTL outputs using pull-up

resistors. Inputs are also equipped with protection circuits

against static discharge and transient excess voltage.
