The TC74AC245, 640 are advanced high speed CMOS OCTAL

BUS TRANSCEIVERs fabricated with silicon gate and double-layer

metal wiring C²MOS technology.

They achieve the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

They are intended for two-way asynchronous communication

between data busses. The direction of data transmission is

determined by the level of the DIR input.

The enable input ( G ) can be used to disable the device so that

the busses are effectively isolated.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features (Note 1)(Note 2)

•

High speed: t = 3.9 ns (typ.) at V

= 5 V

Low power dissipation: I

= 8 μA (max) at Ta = 25°C

High noise immunity: V

= V

= 28% V

(min)

NIH

NIL

Symmetrical output impedance:

|I | = I = 24 mA (min)

Capability of driving 50 Ω transmission lines.

: 1.30 g (typ.)

: 0.22 g (typ.)

: 0.08 g (typ.)

Note 1: Do not apply a signal to any bus terminal when it is in

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 pull

down resistors.
