Quad 2-input XOR in the 4000B family
The CD4030BM96 is a quad 2-input XOR gate from Texas Instruments' 4000B series, in a 14-SOIC package. It operates from 3V to 18V supply, draws 1 µA quiescent current max, and covers the full military temperature range of -55°C to 125°C. Typical use includes parity generation, data comparison, and signal gating in industrial controls, avionics, and battery-powered instrumentation where the wide supply tolerance and low static power matter more than nanosecond switching.
Supply range and logic compatibility
The 3V to 18V supply range lets this gate interface directly with 5V TTL, 12V industrial rails, and 3.3V CMOS without level shifters. Input logic low is 1.5V to 4V; high is 3.5V to 11V — so a 5V logic high from a 74HCT output is comfortably above the threshold. At 15V and 50 pF load, propagation delay is 100 ns — fine for sub-1 MHz buses and debounced switch inputs, but not for fast memory or clock distribution.
Temperature grade and environment
Rated -55°C to 125°C operating, this part is suited for avionics, satellite, downhole instrumentation, and outdoor telecom cabinets where the ambient can swing beyond industrial limits.
Output drive and static power
Each output sources or sinks 3.4 mA — enough to drive one standard CMOS load or a low-current LED indicator, but not a relay coil or bus transceiver without a buffer. The 1 µA max quiescent current makes it a strong choice for always-on monitoring circuits in battery gear: the gate draws essentially nothing until it switches.
Sourcing and lifecycle
No direct second-source cross-reference is listed, but the 4000B family is broadly second-sourced across manufacturers; verify pin-compatibility if substituting.
