Counter Dividers datasheet and documents for CD74HCT161EE4
Counter Dividers Overview
The CD74HCT161EE4 is a high-speed CMOS logic device functioning as a 4-bit binary counter with asynchronous reset. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -55°C to 125°C. The component utilizes synchronous counting and loading mechanisms, featuring two count enable inputs for cascading and look-ahead carry logic for high-speed applications. It is housed in a 16-pin PDIP package.
Counter Dividers Feature Summary
- Synchronous parallel load capability allows data presetting on the clock transition.
- Asynchronous master reset function clears outputs independently of the clock signal.
- Look-ahead carry logic facilitates efficient serial cascading of multiple counters.
Counter Dividers Applications
- High-speed digital counting sequences
- Frequency division circuits
- Digital timing systems
Counter Dividers Procurement Notes
Verify the specific ordering suffix 'E4' against current manufacturer documentation to confirm lead status and material composition. Confirm that the PDIP-16 package dimensions align with the target PCB footprint requirements. Ensure the HCT logic family voltage compatibility matches the system's 5V logic levels before finalizing procurement.
Counter Dividers Selection Notes
Select this component when asynchronous reset behavior is required rather than synchronous clearing found in the 163 series. The HCT logic family ensures direct compatibility with LSTTL inputs while maintaining CMOS power efficiency. Verify that the 4.5V to 5.5V operating voltage range suits the design's power supply constraints.
Counter Dividers Part Context
This part belongs to the Texas Instruments CD74HCT161 family of presettable synchronous counters. It shares functional similarities with the HC161 but offers HCT input compatibility. The device is categorized under high-speed CMOS logic integrated circuits designed for general-purpose binary counting applications.
