SN74LV161AD Description

The SN74LV161AD from Texas Instruments is a 4-bit synchronous binary counter designed for high-performance digital applications. Operating within a 2 V to 5.5 V supply range, this IC is optimized for low-voltage systems while maintaining a high count rate of 95 MHz. It features synchronous operation, ensuring precise timing coordination with clock signals, and includes an asynchronous reset for immediate clearing of the counter. Packaged in a 16-SOIC tube, the device is RoHS3 compliant and suitable for surface-mount (SMD) applications. Its positive-edge triggering and up-counting direction make it ideal for sequential logic designs.

SN74LV161AD Features
