The 4536 is a CMOS programmable timer IC with a 24-stage binary counter (for longer timing intervals), housed in a 16-pin DIP package. Operating on 3V to 18V, it supports external clock or on-chip RC oscillator inputs for flexible timing. With low power consumption, high noise immunity, and ESD protection, it’s ideal for long-term timing applications across -55°C to 125°C, compatible with TTL/CMOS systems.
