TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74HCT245AP,TC74HCT245AF

Octal Bus Transceiver (3-state)

The TC74HCT245A is high speed CMOS OCTAL BUS

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.

It is intended for two-way asynchronous communication

between data busses. The direction of data transmission is

determined by the level of the DIR input.

the busses are effectively isolated.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features (Note 1) (Note 2)

• Wide interfacing ability: LSTTL, NMOS, CMOS

• Output drive capability: 15 LSTTL loads

• Pin and function compatible with 74LS245

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

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

resistors.
