MM54C90/MM74C90 4-Bit Decade Counter
MM54C93/MM74C93 4-Bit Binary Counter
General Description
The
MM54C90/MM74C90
MM54C93/MM74C93 binary counter and complementary
MOS (CMOS) integrated circuits constructed with N- and
P-channel enhancement mode transistors. The 4-bit decade
counter can reset to zero or preset to nine by applying ap-
propriate logic level on the R

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.
