Texas Instruments CD74HC161 High Speed CMOS Logic 4-Bit Binary Counter with Asynchronous Reset CD74HC161EE4

The CD74HC161 is a high-speed CMOS logic 4-bit binary counter featuring asynchronous reset functionality. It operates over a wide temperature range of -55¬8C to 125¬8C and is available in a 16-pin PDIP package. This counter includes two count enable inputs, PE and TE, which facilitate n-bit cascading, and it features look-ahead carry logic to enhance counting speed. The device supports synchronous counting and loading, with reset actions occurring regardless of the state of the count enable inputs. The CD74HC161 is designed for applications requiring reliable counting operations with significant power reduction compared to LSTTL logic ICs. It is compatible with standard TTL logic levels, making it suitable for integration into various digital systems.
