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
01
, R
02
, R
91
and R
92
inputs. Also, a separate flip-flop
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
01
and
R
02
, 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.
