Low-power 555 timer in a through-hole DIP
The Texas Instruments LMC555CN/NOPB is a single 555-type timer/oscillator in an 8-pin DIP package, rated for a maximum frequency of 3 MHz.
The supply current of 150 µA at 5 V means the timer's own power dissipation is negligible in most designs — no heatsinking is needed even at the 3 MHz upper frequency limit.
