HCC/HCF40192B is a presettable BCD up/down counter (dual clock), 40192B is BCD type, 40193B is binary type. The counters can be used alone or cascaded in multiple stages. The counters have high speed asynchronous reset and preset capabilities, and the output terminals use standard symmetrical output characteristics.
The HCC/HCF40192B (BCD) and HCC/HCF40193B (binary) are presettable up/down counters available in 16‑lead plastic or ceramic packages. Each device contains four synchronously clocked D‑type flip‑flops and provides individual clock, preset, carry, and borrow signals for flexible counting and cascading.
The document lists absolute maximum ratings, recommended operating conditions, electrical characteristics such as supply voltage, power dissipation, propagation delays, and mechanical dimensions. It also shows functional and timing diagrams, truth tables, and instructions for cascading multiple packages.
