MM74C93 4-Bit Binary Counter
General Description
The MM74C93 binary counter and complementary 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.
