Quad 2-input NAND gate from the 4000B family
The CD4011BM96: It integrates four independent NAND gates in a single 14-SOIC package, each with two inputs. Typical applications include general-purpose logic gating, oscillator circuits, and interface level translation in industrial control, automotive, and defense electronics where the wide supply tolerance and temperature range are essential.
Supply range and temperature — where this part earns its keep
The 3V to 18V supply range means the CD4011BM96 can be powered directly from an unregulated battery or a loosely regulated rail without needing a separate LDO. The 1 µA quiescent current makes it suitable for battery-backed or always-on logic where every microamp matters. Output drive is rated 3.4 mA for both high and low states, enough to drive a standard CMOS load or a low-power LED indicator.
Propagation delay — not for high-speed buses
Maximum propagation delay is 90 ns at 15V supply with a 50 pF load. That is fine for control signals, pushbutton debounce, or slow clock division.
The 4000B series has been in continuous production for decades, and this part remains a standard catalog item. For dual-sourcing, the CD4025BM96 is a triple 3-input NOR gate sharing the same supply range and temperature grade.
