High Speed CMOS Logic 4-Bit Binary Counter with Asynchronous Reset The HC161, HCT161, HC163, and HCT163 are pre-adjustable synchronous counters, which use a look-ahead transfer logic for use in high-speed counting applications. The HC161 and HCT161 are asynchronous resettable decades and respectively Decades or Binary counters with asynchronous reset; the HC163 and HCT163 are decade and respectively Binary counters that are reset synchronously with the clock cycle. Counting and parallel presetting are both done synchronously with the negative-positive transition of the clock generator. https://elecena.pl/product/23625222/cd74hct161e-counter-binary-up-4-bit-dip-16 2023-06-09 https://elecena.pl/product/23625222/cd74hct161e-counter-binary-up-4-bit-dip-16 2023-09-02 https://elecena.pl/product/23625222/cd74hct161e-counter-binary-up-4-bit-dip-16 2025-12-12 https://elecena.pl/product/23625222/cd74hct161e-counter-binary-up-4-bit-dip-16 2026-01-25
