The TC74VHC299 is an advanced high speed CMOS 8-BIT

PIPO SHIFT REGISTER fabricated with silicon gate C2MOS

technology.

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.
