DESCRIPTION
The M74HC652 is an advanced high-speed CMOS OCTAL BUS TRANSCEIVER AND REGISTER (3-STATE) fabricated with silicon gate C2MOS technology.
This device consists of bus transceiver circuits, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal storage registers.

■ HIGH SPEED:
   fMAX = 79 MHz (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 = 6mA (MIN)
■ BALANCED PROPAGATION DELAYS:
   tPLH ≅ tPHL
■ WIDE OPERATING VOLTAGE RANGE:
   VCC (OPR) = 2V to 6V
■ PIN AND FUNCTION COMPATIBLE WITH
   74 SERIES 652
