The CD4536BDWR is a programmable timer from Texas Instruments, part of the CD45xx logic family, capable of generating precise time delays or frequency outputs from a single RC oscillator or external clock. The count range spans 2 to 2^24 stages, selectable via external pins, giving the designer a wide window from a few cycles to over 16 million counts before the output toggles. Maximum oscillator frequency is 5 MHz, and the device operates from a 3V to 18V supply, drawing only 3 mA typical — suitable for battery-backed or low-power instrumentation.
