DESCRIPTION

The M54/74HC299/323 are high speed CMOS 8-

BIT PIPO SHIFT REGISTERS (3-STATE) fabri-

cated with silicon gate C

They achieve the high speed operation similar to

equivalent LSTTL while maintaining the CMOS low

power consumption.

These devices have four modes (HOLD, SHIFT

LEFT, SHIFT RIGHT and LOAD DATA). Each mode

is chosen by two function select inputs (S0, S1).

When one or both enable inputs, (G1, G2) are high,

the eight input/output terminals are in the high-

impedance state ; however sequential operation or

clearing of the register is not affected.

Clear function on the HC299 is asynchronous to

CLOCK, while the HC323 is cleared synchronous to

clock.

All inputs are equipped with protection circuits

against static discharge and transient excess volt-

age.
