Texas Instruments CD74HC161 High Speed CMOS Logic 4-Bit Binary Counter with Asynchronous Reset CD74HC161MG4

The CD74HC161 is a high-speed CMOS logic 4-bit binary counter featuring asynchronous reset capabilities. It operates over a wide temperature range of -55¬8C to 125¬8C and is designed for synchronous counting and loading. The device includes two count enable inputs, PE and TE, which facilitate n-bit cascading, making it suitable for applications requiring multiple counters. The look-ahead carry feature enhances high-speed counting by simplifying serial cascading. The counter can be reset regardless of the state of the count enable inputs, ensuring reliable operation. It is compatible with standard TTL logic levels, allowing for easy integration into existing designs. The CD74HC161 is available in a 16-lead SOIC package.
