DESCRIPTION
The M74HC164 is an high speed CMOS 8 BIT SIPO SHIFT REGISTER fabricated with silicon gate C2MOS technology.
The M74HC164 is an 8 bit shift register with serial data entry and an output from each of the eight stages. Data is entered serially through one of two inputs (A or B), either of these inputs can be used as an active high enable for data entry through the other input. An unused input must be high, or both inputs connected together.

■ HIGH SPEED :
   fMAX = 62MHz (TYP.) at VCC = 6V
■ LOW POWER DISSIPATION:
   ICC =4µA(MAX.) at TA=25°C
■ HIGH NOISE IMMUNITY:
   VNIH = VNIL = 28 % VCC (MIN.)
■ SYMMETRICAL OUTPUT IMPEDANCE:
   |IOH| = IOL = 4mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL
■ WIDE OPERATING VOLTAGE RANGE:
   VCC (OPR) = 2V to 6V
■ PIN AND FUNCTION COMPATIBLE WITH
   74 SERIES 164
