7493 Datasheet PDF – 4-Bit Binary Ripple Counter – NXP

Part Number : 7493, 74HC93, 74HCT93

Function : 4-bit binary ripple counter

Manufacturers : NXP Semiconductors.

Pinouts :

7493 pinout

 

Description :

The 74HC93, 74HCT93 are high-speed Si-gate CMOS

devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.

The 74HC/HCT93 are 4-bit binary ripple counters. The devices consis of four master-slave flip-flops internally connected to provide a divide-by-two section and a divide-by-eight section. Each section has a separate clock input (CP0 and CP1) to initiate state changes of the counter on the HIGH-to-LOW clock transition. State 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.

The 74HC/HCT93 are 4-bit binary ripple counters.
