CD4001BM SOP-14 Quad 2-Input NOR Gate CMOS IC (5-Pack)

The CD4001BM is a quad 2-input NOR gate in a surface-mount SOP-14 package, built on CMOS technology for wide supply voltage operation (3V–18V). Each package contains four independent NOR gates — the complement to the CD4011BM NAND gate — and is a fundamental building block for digital logic, RS latches, oscillators, and signal conditioning circuits.

Why Choose CD4001BM?

Universal Logic Gate — NOR gates implement any Boolean function (NOR is functionally complete)
Wide Supply Range — 3V–18V covers 3.3V, 5V, 9V, and 12V systems
CMOS Technology — Ultra-low quiescent current for battery-powered designs
SOP-14 SMD Package — Compact footprint for PCB-level integration
DIP-Compatible Logic — Same function as CD4001BE (DIP-14)

Typical Applications

RS latch (Set-Reset flip-flop) using two NOR gates
Combinational logic circuits (AND, OR, NOT, NAND from NOR)
Schmitt trigger oscillator and clock generator
Signal inversion and buffering
Debounce circuit for mechanical switches
Low-power IoT sensor interface logic

FAQ

Q: How do I make an RS latch with CD4001BM?
A: Cross-couple two NOR gates: output of gate 1 → input of gate 2, output of gate 2 → input of gate 1. Apply S (Set) to gate 1 free input, R (Reset) to gate 2 free input.

Q: Can CD4001BM replace CD4001BE?
A: Yes — electrically identical, different package (SOP-14 SMD vs DIP-14 through-hole).
