Texas Instruments CD54HC163 High Speed CMOS Logic 4-Bit Binary Counter with Synchronous Reset CD54HC163F3A

The CD54HC163 is a high-speed CMOS logic 4-bit binary counter featuring synchronous reset capabilities. It operates within a temperature range of -55¬8C to 125¬8C and is designed for applications requiring precise counting and loading operations. The device includes two count enable inputs, PE and TE, which facilitate n-bit cascading, allowing for the connection of multiple counters. The CD54HC163 supports synchronous counting and loading, with all operations triggered by the clock's negative-to-positive transition. It features a look-ahead carry function that simplifies cascading and enhances counting speed. The counter can be reset synchronously with the clock, ensuring reliable operation in various applications. With a fanout of 10 LSTTL loads for standard outputs and 15 LSTTL loads for bus driver outputs, the CD54HC163 is suitable for high-performance digital circuits. The device is compatible with both CMOS and LSTTL logic levels, making it versatile for integration into existing systems.
