The MC74HC390ADR2G from On Semiconductor is a high-performance silicon-gate CMOS dual 4-stage binary ripple counter. This device consists of two independent 4-bit counters, each comprising a divide-by-two and a divide-by-five section. These sections can be cascaded to create various combinations of division ratios, up to a divide-by-100 counter.
The counter features separate clock inputs for each section and asynchronous reset capabilities for each 4-bit counter. Flip-flops within the counters are triggered by high-to-low transitions of the clock input. The device is designed for a wide operating voltage range of 2.0V to 6.0V and supports a count rate of up to 50 MHz.
With an output drive capability of 10 LSTTL loads, the MC74HC390ADR2G directly interfaces with CMOS, NMOS, and TTL logic families. It is available in a 16-SOIC surface mount package, making it suitable for various electronic designs. The operating temperature range is from -55°C to 125°C.
This counter is Pb-free, halogen-free, BFR-free, and RoHS compliant, aligning with modern environmental standards for electronic components.
