TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74HCT652AP

Octal Bus Transceiver/Register (3-state)

The TC74HCT652A is high speed CMOS OCTAL BUS

technology.

It achieves the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

Its inputs are compatible with TTL, NMOS, and CMOS output

voltage levels.

This device is bus transceiver with 3-state outputs, D-type

flip-flops, and control circuitry arranged for multiplexed

transmission of data directly from the internal registers.

ALL inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features (Note 1) (Note 2)

• Output drive capability: 15 LSTTL loads

• Pin and function compatible with 74LS652

Note 1: Do not apply a signal to any bus terminal when it is in the out put mode. Damage may result.

Note 2: All floating (high impedance) bus terminals must have their input levels fixed by means of pull up or pull

down resistors.
