It delivers four independent XOR functions on a single chip, each with two inputs, for general-purpose logic gating in mixed-voltage or high-temperature boards. ## What the key ratings mean on the bench Quiescent current maxes at 1 µA across the full supply range — the gate draws essentially nothing when idle, so it won't eat into a sleep-mode budget on a low-power sensor node or a coin-cell-powered data logger. Output drive is rated 3.4 mA source and sink at the same figure — symmetrical drive means the high and low edges into a 50 pF load have similar rise/fall times, which simplifies timing margin in a clock or data path. Propagation delay is 100 ns max at 15V with a 50 pF load, so this is a medium-speed CMOS gate, not a high-speed logic family. Input logic thresholds scale with supply: low-level threshold is 1.5V to 4V, high-level is 3.5V to 11V (at Vdd=10V). This means the gate interprets a 3.3V logic-high from a microcontroller as a valid '1' when running on a 5V or higher supply, but may not see it as a '1' at a 3V supply — check the threshold against your driver's Voh at the operating Vdd. ## Package, rework, and board-fit Supplied in Tape & Reel (TR) and Cut Tape (CT) options — the TR format is the production-volume carrier; CT suits prototype or low-volume builds without committing to a full reel.","metaTitle":"CD4070BMT Texas Instruments XOR Gate, 14-SOIC, 3V-18V","metaDescription":"Texas Instruments CD4070BMT quad 2-input XOR gate in 14-SOIC. 3V-18V supply, -55°C to 125°C range, 1 µA quiescent.
