Overview
The MC14528B, specifically the MC14528BDG, is a dual, retriggerable, resettable monostable multivibrator produced by onsemi. This integrated circuit can be triggered from either edge of an input pulse and generates an output pulse with a duration determined by external timing components, CX and RX. It is designed to operate within a supply voltage range of 3.0 Vdc to 18 Vdc and is capable of driving two low-power TTL loads or one low-power Schottky TTL load over the rated temperature range. For new designs requiring pulse widths less than 10 µs, the MC14528B is an ideal choice, while for pulse widths greater than 10 µs, the pin-for-pin compatible MC14538 is recommended.
