Part Details:

M74HC590 8 BINARY COUNTER REGISTER WITH 3 STATE OUTPUT s HIGH SPEED: fMAX = 61 MHz (TYP.) at VCC = 6V s LOW POWER DISSIPATION:ICC = 4µA(MAX.) at TA=25°C s HIGH NOISE IMMUNITY:VNIH = VNIL = 28 % VCC (MIN.) s SYMMETRICAL OUTPUT IMPEDANCE: DIP SOP TSSOP |IOH| = IOL = 6mA (MIN) for QA ~ QH OUTPUT |IOH| = IOL = 4mA (MIN) for RCO OUTPUT s BALANCED PROPAGATION DELAYS: ORDER CODES tPLH tPHL PACKAGE TUBE T & R s WIDE OPERATING VOLTAGE RANGE:V DIP M74HC590B1R CC (OPR) = 2V to 6V SOP M74HC590M1R M74HC590RM13TR s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 590 TSSOP M74HC590TTR DESCRIPTION cascading, a ripple carry output RCO is provided. The M74HC590 is an high speed CMOS 8-BIT Expansion is easily accomplished by tying RCO of BINARY COUNTER REGISTER (3 STATE) the first stage to CCKEN of the second stage, etc. fabricated with silicon gate C2MOS technology. Both the counter and register clocks are positive This device contains an 8-bit binary counter that edge triggered. If the user wishes to connect both feeds an 8-bit storage register. The storage clocks together, the counter state will always be register has parallel outputs. Separate clocks are one count ahead of the register. Internal circuitry provided for both the binary counter and storage prevents clocking from the clock enable. All inputs register. The binary counter features a direct clear are equipped with protection circuits against static
