The CD4009UBPWR from Texas Instruments is a 14-stage Static CMOS Counter/Divider with a Carrier Detect feature. It consists of five synchronous 4-bit counters, a complementary four-bit latch and logic for synchronous reset, gated zero reset, and carry in. Each of the synchronous counters can be cascaded to operate as an 8-bit, 12-bit, or 14-stage counter/divider. The dynamic logic keeps the active count value at the outputs of each counter and at the inputs of the next counter. The CD4009UBPWR also includes a Carrier Detect circuit. The CD4009UBPWR is a power limited rating device, specified over an operating temperature range of -55°C to 125°C.
