25 MHz count rate with asynchronous reset
The CD74HCT4024E is a 7-bit binary counter from the 74HCT series, counting up on the negative edge of the clock input at a maximum count rate of 25 MHz. The asynchronous reset pin clears all bits to zero independent of the clock state, which means the counter resets immediately when the reset line is asserted — no need to wait for a clock edge to synchronize the clear.
Through-hole 14-DIP for breadboard and legacy sockets
Housed in a 14-pin DIP (0.300-inch body width, 7.62 mm pitch), the CD74HCT4024E is a through-hole part that drops into standard DIP sockets or solders directly into a PCB. The 14-PDIP supplier package footprint is the same as any 14-pin DIP logic IC — no board respin needed if the existing layout already accepts a 74HCT or 74LS part in the same form factor. The single-element, 7-bit counter occupies one logic position. The negative-edge trigger means the counter advances on the falling edge of the clock, which is the opposite of most 74-series counters that trigger on the rising edge — a detail that matters when cascading multiple counters or interfacing with a system clock that expects positive-edge logic.
