IC timers are semiconductor circuits that generate or set timing for electronics circuits

Specialty IC timing devices are specialty or proprietary products related to IC timing devices.

Electronic counters and electronic timers are completely electronic units for performing a variety of counter or timer functions

IC phase-locked loops (PLL) are closed-loop frequency controls that are based on the phase difference between the input signal and the output signal of a controlled oscillator.

Time delay relays and solid state timers use solid state electronic devices to provide a time delay

Counter and timer boards are computer cards that perform digital counting and/or timing functions

Flip-flops are digital logic devices that synchronize changes in output state (1 or 0) according to a clocked input.
