HCT161 Description

Short technical summary and product information.

The Harris Semiconductor HCT161 is a high-speed CMOS logic integrated circuit designed as a 4-bit binary counter with asynchronous reset functionality. This counter utilizes HCT technology, providing direct LSTTL input logic compatibility and CMOS input compatibility.

 

Key electrical characteristics include a wide operating temperature range of -55°C to 125°C and an operating voltage range of 4.5V to 5.5V for HCT types. The device features balanced outputs and a positive input clamp diode. Standard outputs offer a fanout of 10 LSTTL loads, while bus driver outputs support up to 15 LSTTL loads.

 

Available in SOIC (D) and PDIP (N) packages, the HCT161 is suitable for various digital logic applications requiring precise counting and cascading capabilities. Its design emphasizes balanced propagation delays and transition times, offering significant power reduction compared to LSTTL logic.

 

This counter is well-suited for applications needing reliable binary counting with asynchronous reset, such as digital control systems, frequency division, and data sequencing.
