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.","metaTitle":"Texas Instruments CD74HCT4024E 7-bit Binary Counter, 25 MHz","metaDescription":"Texas Instruments CD74HCT4024E 7-bit binary counter, 25 MHz count rate, asynchronous reset, -55°C to 125°C, 14-DIP.

The 4024E counts up to 128 states (2^7) on one element; the 390E counts 0-9 per decade on two independent elements. The 4024E uses a negative-edge trigger; the 390E also uses negative-edge trigger. Both are asynchronous reset, through-hole 14-DIP, and operate over -55°C to 125°C. They are not pin-compatible — the 4024E has a single clock and reset, while the 390E has two clock inputs and two reset inputs."},{"question":"What compliance documentation does Texas Instruments provide for CD74HCT4024E?","answer":"The CD74HCT4024E is ROHS3 compliant.
