CD74HCT163E

Counter Dividers Overview

The CD74HCT163E is a synchronous 4-bit binary counter manufactured by Harris Corporation. It operates within a supply voltage range of 4.5V to 5.5V and features positive edge triggering for clock inputs. The device utilizes CMOS technology and supports up-counting operations with synchronous reset functionality. It is housed in a 16-pin Dual In-Line Package (PDIP) designed for through-hole mounting. The component functions as a single-element logic circuit capable of reliable digital counting applications across industrial temperature ranges.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting architecture
• Positive edge triggered clock operation
• CMOS technology construction
• Through-hole 16-pin DIP packaging

Counter Dividers Applications

• Digital frequency division circuits
• Synchronous timing sequence generation
• Binary data accumulation systems

Counter Dividers Procurement Notes

Verify the manufacturer designation, as Texas Instruments also produces this part number variant. Confirm the package style matches the required 16-PDIP form factor. Ensure the specific lot corresponds to Harris Corporation production if that origin is strictly required for the design. Check RoHS compliance status against current regulatory requirements for the target market.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with positive edge triggering is required. The HCT series ensures compatibility with standard TTL logic levels while maintaining CMOS power characteristics. The PDIP package is suitable for prototyping or applications requiring manual insertion. Verify that the operating voltage range aligns with the system's 5V power supply rails.

Counter Dividers Part Context

This component belongs to the 74HCT logic family, which bridges high-speed CMOS performance with TTL input compatibility. The base model 74HCT163 defines the functional specifications for a synchronous 4-bit binary counter. The 'CD' prefix typically indicates commercial temperature range availability, while the 'E' suffix denotes the specific plastic dual in-line package configuration used in this variant.

Counter Dividers Replacement Considerations

The 74HCT163D,653 from Nexperia is listed as an obsolete alternative with available substitutes such as the CD74HCT163M from Texas Instruments. Verify pinout compatibility before substituting. Ensure the replacement maintains the same synchronous reset and positive edge trigger characteristics.
