4-Bit Binary Counter
General Description
The MM74C93 binary counter and complementary MOS
(CMOS) integrated circuits constructed with N- and P-
channel enhancement mode transistors. The 4-bit binary
counter can be reset to zero by applying high logic level on
inputs R
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.
