MM74C90 • MM74C93
4-Bit Decade Counter • 4-Bit Binary Counter
General Description
The MM74C90 decade counter and the MM74C93 binary
counter and complementary MOS (CMOS) integrated cir-
cuits constructed with N- and P-channel enhancement
mode transistors. The 4-bit decade counter can reset to
zero or preset to nine by applying appropriate logic level on
the R
on the A-bit enables the user to operate it as a divide-by-2,
5 or 10 frequency counter. The 4-bit binary counter can be
reset to zero by applying high logic level on inputs R
R
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.
