Overview
M74HC393 DUAL BINARY COUNTER s HIGH SPEED : fMAX = 79 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: |IOH| = IOL = 4mA (MIN) s BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL s WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 393 DESCRIPTION The M74HC393 is an high speed CMOS DUAL BINARY COUNTER fabricated with silicon gate C2MOS technology.
This counter circuit contains independent ripple carry counters and two 4-bit ripple carry binary counters, which can be cascaded to create a single divide by 256 counter.
Each 4-bit counter is incremen...
