8-bit synchronous down counter with asynchronous reset
The Texas Instruments CD74HCT40103M is an 8-stage synchronous down counter from the 74HCT logic family, designed for frequency division, timing generation, and event counting in 5 V systems. It counts down on each positive clock edge and clears asynchronously when the reset input is asserted.
14 MHz count rate — timing budget for 5 V systems
The 14 MHz maximum count rate sets the upper frequency for reliable down-counting. In a typical divide-by-N application, the input clock must stay below this limit to avoid missing edges. At 5 V ± 0.5 V supply, the HCT family provides LSTTL-compatible inputs and CMOS outputs, so it interfaces directly with 5 V microcontrollers and legacy TTL logic without level translation. The positive-edge trigger simplifies synchronization with most clock sources.
