IC M74HC299

DESCRIPTION
The M74HC299 is an high speed CMOS 8 BIT PIPO SHIFT REGISTER (3-STATE) fabricated
with silicon gate C2MOS technology. This device has 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 M74HC299 is asynchronous to CLOCK. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

HIGH SPEED :
fMAX = 80MHz (TYP.) at VCC = 6V
LOW POWER DISSIPATION:
ICC =4mA(MAX.) at TA=25
