DESCRIPTION
The M74HC590 is an high speed CMOS 8-BIT BINARY COUNTER REGISTER (3 STATE) fabricated with silicon gate C2MOS technology.

■ HIGH SPEED: fMAX = 61 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) for QA ~ QH OUTPUT |IOH| = IOL = 4mA (MIN) for RCO OUTPUT
■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL
■ WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 590
