MC14001BCPG Description

The MC14001BCPG from onsemi is a quad 2-input NOR gate IC belonging to the 4000B series, designed for robust digital logic applications. Housed in a 14-pin DIP package, this through-hole-mount device operates across a wide 3V to 18V supply range, making it versatile for both low-voltage and industrial-level designs. With a maximum propagation delay of 80ns at 15V/50pF, it balances speed and power efficiency, drawing a quiescent current of just 1µA (max). The IC features 4 independent NOR gates, each with 2 inputs, and delivers symmetrical output drive capability (8.8mA sink/source). Its CMOS technology ensures compatibility with TTL levels while offering superior noise immunity.
