DESCRIPTION

The M54/74HC299/323 are high speed CMOS 8­BIT PIPO SHIFT REGISTERS (3-STATE) fabri­cated withsilicon gateC2MOS technology.

They achieve the high speed operation similar to
equivalent LSTTL whilemaintaining the CMOS low
powerconsumption.

These devices have four modes (HOLD, SHIFT
LEFT,SHIFTRIGHTandLOADDATA).Eachmode
is chosen by two function select inputs (S0, S1).
When one orboth enableinputs, (G1, G2)are high,
the eight input/output terminals are in the high­impedance state ; however sequential operation or
clearing of the register is not affected.

Clear function on the HC299 is asynchronous to
CLOCK,while theHC323iscleared synchronous to
clock.

All inputs are equipped with protection circuits
against static discharge and transient excess volt­age.
