MM54C90 MM74C90 4-Bit Decade Counter
MM54C93 MM74C93 4-Bit Binary Counter
General Description
The MM54C90 MM74C90 decade counter and the
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 R01 R02 R91 and R92 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 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
