CD54HC4017F3A

The CD54HC4017F3A from Texas Instruments is a high-speed silicon-gate CMOS 5-stage Johnson counter featuring ten decoded outputs. Each output sequentially goes high on the low-to-high transition of the clock input and remains high for one clock period of the ten-clock cycle.

This device operates fully statically and features buffered inputs, a common reset, and positive-edge clocking. It offers balanced propagation delay and transition times, along with high noise immunity. The operating voltage range is from 2V to 6V, and it is characterized for operation over the full military temperature range of -55°C to 125°C.

The CD54HC4017F3A is packaged in a 16-pin Ceramic DIP (CDIP) package. The terminal count output can be used with the clock enable input to cascade multiple stages, with the clock enable disabling counting when high. The master reset input sets all decoded outputs, except 0, to low when taken high.

This counter is suitable for various digital logic applications requiring sequential output generation and counting functions within a wide temperature range.
