It performs the logical equivalence function — output is high when both inputs match — across a supply range of 3V to 18V. The wide 3V to 18V supply tolerance means this gate can interface directly between 5V and 12V or 15V logic domains without a level translator, simplifying mixed-voltage board layouts. Rated for -55°C to 125°C operation, the CD4077BMT suits avionics, downhole instrumentation, and engine-bay electronics where the ambient temperature exceeds the commercial or industrial range. Maximum quiescent current is 1 µA across the full supply range — the gate's own draw is negligible in battery-powered sensor nodes or energy-harvesting designs where every microamp matters. Propagation delay is specified as 100 ns maximum at 15V supply with a 50 pF load. At lower supply voltages the delay increases; the input logic levels shift accordingly — low threshold is 1.5V to 4V, high threshold is 3.5V to 11V — so the timing margin must be checked at the actual operating voltage. Output drive capability is 3.4 mA for both source and sink at rated supply — sufficient for driving CMOS inputs on the same board, but a buffer is needed for longer traces or higher capacitive loads. ## Active lifecycle and compliance documentation No other regulatory certifications (UL, IEC, AEC-Q) are listed in the available documentation.","metaTitle":"TI CD4077BMT XNOR Gate, 4000B, 3-18V, 14-SOIC","metaDescription":"Texas Instruments CD4077BMT quad 2-input XNOR gate, 4000B series, 3V to 18V supply, -55°C to 125°C, 1µA quiescent.
