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.
