The CD74AC161M96 from Texas Instruments is a high-performance 4-bit synchronous binary counter designed for precision counting applications. Operating within a 1.5V to 5.5V supply range, this IC delivers reliable performance with a 90 MHz count rate, making it suitable for high-speed digital systems. The device features synchronous operation, ensuring all state changes occur simultaneously with the clock signal, while its asynchronous reset allows immediate initialization. Packaged in a 16-SOIC and supplied in Tape & Reel (TR), it is optimized for surface-mount assembly. Though marked as obsolete, it remains a robust choice for legacy designs requiring low-power, high-speed counting.
The CD74AC161M96 offers a blend of speed, reliability, and versatility for synchronous counting applications. Its wide voltage range and asynchronous reset make it adaptable to diverse designs, while its high-frequency operation caters to demanding digital systems. Though obsolete, its 74AC-series robustness ensures continued utility in legacy or cost-sensitive projects requiring precision counting. Engineers valuing low-power, high-performance logic will find this IC a pragmatic solution for timing and control tasks.
