High Speed CMOS Logic

4-Bit Binary Ripple Counter

Description

The Harris CD74HC93 and CD74HCT93 are high speed
silicon-gate CMOS devices and are pin-compatible with low
power Schottky TTL (LSTTL). These 4-bit binary ripple
counters consist of four master-slave flip-flops internally
connected to provide a divide-by-two-section and a divid- by­eight-section. Each section has a separate clock input (
and

CP1) to innate state changes of the counter on the HIGH
to LOW clock transition. Sate changes of the Qn outputs do
not occur simultaneously because of internal ripple delays.
Therefore, decoded output signals are subject to decoding
spikes and should not be used for clocks or strobes.

A gated AND asynchronous master reset (MR1 and MR2 is
provided which overrides both clocks and resets (clears) all
flip-flops.

Because the output from the divide by two section is not
internally connected to the succeeding stages, the device
may be operated in various counting modes.

In a 4-bit ripple counter the output Q0 must be connected
externally to input
to clock input
8, and 16 are performed at the Q0, Q1, Q2, and Q3 outputs
as shown in the function table. As a 3-bit ripple counter the
input count pulses are applied to input

Simultaneous frequency divisions of 2, 4, and 8 are available
at the Q
flop is available if the reset function coincides with the reset
of the 3-bit ripple-through counter.
