8-Bit Pipo Shift Register with Asynchronous Clear

The TC74VHC299 is an advanced high speed CMOS 8-BIT

PIPO SHIFT REGISTER fabricated with silicon gate C²MOS

technology.

TC74VHC299F

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

It has a four modes (HOLD, SHIFT LEFT, SHIFT RIGHT and

LOAD DATA) controlled by the two selection inputs (S0, S1).

When one or both enable ( G1 , G2 ) are high, the eight I/O are

forced to the high-impedance state; however, sequential

operation or clearing of the register is not affected.

All inputs are equipped with protection circuits against static

discharge.

Pin and function compatible with 74ALS299

Note 1: Do not apply a signal to A/QA to H/QH bus terminal when it is in the output mode. Damage may result.

Note 2: All floating (high impedance) A/QA to H/QH bus terminals must have their input levels fixed by means of pull

up or pull down resistors.

Note 3: A parasitic diode is formed between A/QA to H/QH bus and V

be used to interface 5 V to 3 V systems directly.
