Programmable timer with wide count range
The Texas Instruments CD4536BPW is a programmable timer IC in the Clock & Timing ICs category, capable of generating time delays from a count of 2 up to 2²⁴ (16,777,216) at a maximum frequency of 5 MHz. Operating from a 3V to 18V supply and drawing only 3 mA, it fits designs where a single IC must handle both wide voltage tolerance and low power draw across industrial or military temperature spans.
Package and temperature grade
Rated for -55°C to 125°C operating temperature, this is the military-grade range — suitable for avionics, downhole instrumentation, or satellite power-on sequencing where the ambient envelope extends beyond commercial or industrial limits.
