What this counter is and where it fits
The CD74HC192PWT is a 4-bit synchronous up/down decade counter from the 74HC family. It counts on the positive edge of the clock, with separate up and down clock inputs so you can increment or decrement without external direction logic. The asynchronous reset clears the outputs regardless of the clock state — handy if you need a hard reset on power-up or a fault condition without waiting for a clock edge. It's a single-element, 4-bit counter in a 16-TSSOP surface-mount package, rated across the full military temperature range of -55°C to 125°C. Typical applications include event counting, frequency division, and industrial sequencing where you need a clean, synchronous count with a simple reset.
24 MHz count rate — what it means for the bus
At 24 MHz, this counter can handle fast encoder pulses or high-speed event streams without missing edges.
Lifecycle and sourcing
This part is Active and ROHS3 compliant, so there's no LTB risk and no end-of-life clock ticking. It's a current-production 74HC device from Texas Instruments, available through independent distribution. No stock or price figures here — send an RFQ for the real numbers.
