Frequently Asked Questions
What is the CD74HC393E and what logic family does it belong to?
The CD74HC393E is a dual 4-bit binary ripple counter from Texas Instruments belonging to the HC (High-Speed CMOS) logic family. It operates over a supply voltage range of 2V to 6V and supports clock frequencies up to 40 MHz. The device is packaged in a 14-pin PDIP through-hole package, making it suitable for prototyping and socketed board designs.
What are the typical applications for the CD74HC393E?
The CD74HC393E is commonly used in digital counters, frequency dividers, event counters, and timing circuits. Its dual 4-bit architecture allows cascading to create 8-bit or wider counters without additional chips. It is found in embedded systems, test instruments, digital clock circuits, and memory address decoders where binary counting sequences are fundamental to system operation.
Can the CD74HC393E be cascaded to form wider counters?
Yes, the CD74HC393E's dual 4-bit ripple counter sections can be cascaded internally to create an 8-bit counter, and multiple CD74HC393E devices can be further cascaded for 12-bit, 16-bit, or wider binary counting chains. The Q3 output of each 4-bit counter stage is connected to the clock input of the next stage to extend the count range as needed for the application.
What package does the CD74HC393E use and how does it compare to SMD alternatives?
The CD74HC393E uses a 14-pin PDIP (Plastic Dual In-Line Package) through-hole format, ideal for breadboard prototyping and socketed PCB designs. For surface-mount applications, Texas Instruments offers equivalent devices in SOIC (e.g., CD74HC393M) and SSOP packages. The PDIP variant is preferred in educational and prototyping environments where manual assembly and easy replacement are priorities.
