Quad 2-input XNOR gate for automotive logic — what it is, what it does
Each of the four independent circuits performs the Boolean XNOR function: output is high when both inputs are equal. The Schmitt-trigger inputs provide noise immunity on slowly changing or noisy signals, making the part suitable for sensor interfaces, switch debouncing, and control logic in automotive body electronics, powertrain, and industrial environments where signal integrity matters.
The supply range spans 2V to 6V, covering both 3.3V and 5V logic rails common in automotive ECUs. Quiescent current is 2 µA maximum — negligible in battery-backed or always-on modules. Output drive is 7.8 mA sink and source at rated conditions, enough to drive downstream CMOS logic inputs or low-power LEDs directly. Propagation delay is 16 ns at 6V, 50 pF load — fast enough for control loops and state machines running at moderate clock speeds.
Mounting and integration notes
Surface-mount 14-TSSOP package, 0.173" (4.40 mm) body width. The supplier device package is 14-TSSOP. CT is for prototypes or small builds. No special thermal management is needed; the 2 µA quiescent current keeps self-heating negligible across the temperature range.
