What are the key features of SN74HC393ANS?
- Dual independent 4-bit binary ripple counters in a single SOIC package for compact PCB layouts
- Wide supply voltage range from 2 V to 6 V covering both 3.3 V and 5 V digital systems
- Clock frequency up to 25 MHz enabling high-speed frequency division and timing generation
- Separate asynchronous clear and clock inputs per counter section for independent reset control
What is SN74HC393ANS used for?
The SN74HC393ANS is commonly used as a frequency divider, event counter, and timing pulse generator in digital electronics. Its dual 4-bit structure allows cascading for longer count sequences or simultaneous independent counting in a single 14-pin SOIC footprint. Typical applications include clock division in embedded systems, LED sequencing, and address generation for memory interfaces.

Frequently Asked Questions
What supply voltage range does SN74HC393ANS support and at what clock speed does it operate?
SN74HC393ANS operates from a 2 V to 6 V supply and can be clocked at up to 25 MHz, making it compatible with both 3.3 V and 5 V logic systems. Lower supply voltages reduce switching speed, so verify timing margins when operating below 4.5 V at high frequencies.
How can SN74HC393ANS be cascaded to create counters longer than 4 bits?
Each of the two 4-bit counters in SN74HC393ANS has an independent QD output that transitions on every 16th clock pulse, which can directly drive the clock input of an external counter section. By connecting QD of one section to the clock of another 74HC393 or similar counter, you can create 8-bit or 12-bit ripple counters without additional logic.
Which package does SN74HC393ANS use and how does it compare to the DIP version for PCB space?
SN74HC393ANS is housed in a 14-pin SOIC package with 1.27 mm pin pitch, consuming roughly 60% less PCB area compared to the equivalent 14-pin PDIP version. Surface-mount assembly also improves reliability in vibration-prone environments and enables smaller board designs.
When is SN74HC393ANS a practical alternative to a microcontroller timer for frequency division?
SN74HC393ANS is preferred over a microcontroller timer when a deterministic, glitch-free 4-bit count sequence is needed without firmware overhead. It divides an input clock by any power of 2 from 2 to 16 using only the QA–QD outputs, operating continuously at up to 25 MHz with zero CPU intervention.
