MM74C93 4-Bit Binary Counter October 1987 Revised January 2004 MM74C93 4-Bit Binary Counter General Description The MM74C93 binary counter and plementary MOS (CMOS) integrated circuits constructed with N- and Pchannel enhancement mode transistors. The 4-bit binary counter can be reset to zero by applying high logic level on inputs R01 and R02, and a separate flip-flop on the A-bit enables the user to operate it as a divide-by-2, -8, or -16 divider. Counting occurs on the negative going edge of the input pulse. All inputs are protected against static discharge damage. Features s Wide supply voltage range: 3V to 15V s Guaranteed noise margin: 1V s High noise immunity: 0.45 VCC (typ.) s...
