Key Features
- 4-bit up-counting binary ripple counter compatible with HC/UH CMOS logic family for broad system interoperability
- 14-pin PDIP through-hole package ideal for prototyping, education, and legacy board repair without SMT tooling
- 50 pF load capacitance rating ensuring reliable output switching even when driving moderately capacitive bus lines
Applications
The CD74HC93E is used in digital frequency division, event counting, and timing circuits where a simple 4-bit ripple counter suffices. It fits breadboard-friendly prototyping setups and legacy through-hole PCB designs in industrial timers, educational trainers, and pulse-counting measurement instruments. Multiple units can be cascaded to build 8-bit or wider counters without additional glue logic.

Frequently Asked Questions
How many bits does the CD74HC93E count, and can it be cascaded for wider counter chains?
The CD74HC93E is a 4-bit binary ripple counter that counts up through 16 states (0 to 15). Multiple CD74HC93E devices can be cascaded by connecting the most significant output bit of one stage to the clock input of the next, extending the count width to 8 bits, 12 bits, or beyond with minimal additional wiring.
What load capacitance and logic family does CD74HC93E support in mixed-logic designs?
The CD74HC93E is rated for a 50 pF load capacitance per output, part of the HC/UH high-speed CMOS logic family. Operating from 2 V to 6 V supply, it interfaces directly with other HC, HCT, and TTL-compatible logic without level-shifting in most 3.3 V to 5 V mixed designs, making it versatile for legacy and modern board revisions.
Which timing and frequency-division circuits benefit from using CD74HC93E?
Digital clock dividers, frequency prescalers, and pulse-counting circuits in microcontroller-based instruments commonly use the CD74HC93E. Its 4-bit binary count provides division ratios of 2, 4, 8, or 16 from a single clock input—useful in audio-frequency generators, LED sequencers, and event-count displays where a small CMOS counter reduces software overhead.
What package and pin count does CD74HC93E offer, and why does it suit through-hole prototyping?
The CD74HC93E comes in a 14-pin PDIP (R-PDIP-T14) through-hole package with 2.54 mm row pitch, fitting standard breadboards and DIP IC sockets directly. This package style requires no SMT reflow equipment, making it accessible for rapid prototyping, student lab exercises, and field repair of industrial boards where through-hole soldering is the standard process.
