4-Bit Binary Ripple Counter

Features

Description

• Can Be Conﬁgured to Divide By 2, 8, and 16

• Asynchronous Master Reset

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- by-

eight-section. Each section has a separate clock input (CP0

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.

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.

• HCT Types

- 4.5V to 5.5V Operation

- Direct LSTTL Input Logic Compatibility,

In a 4-bit ripple counter the output Q0 must be connected

externally to input CP1. The input count pulses are applied

to clock input CP0. Simultaneous frequency divisions of 2, 4,

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 CP1.
