DESCRIPTION
The M74HC593 is an high speed CMOS 8-BIT REGISTER COUNTER (3 STATE) fabricated with silicon gate C2MOS technology.
This device consists of a parallel input, 8 bit storage register feeding an 8 bit binary counter. Both the counter and register clocks are positive edge triggered. In addition, the counter has direct load and clear functions.
■ HIGH SPEED: fMAX = 20 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:
IOL = |IOH| = 6mA (MIN) for Qn
IOL = |IOH| = 4mA (MIN) for RCO
■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL
■ WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 593
