This datasheet provides detailed information on the SN74LV21A device, including functionality, operating voltage range, maximum tpd, typical VOLP, typical VOHV, Ioff, Latch-Up performance, ESD protection, etc.
The SN54LV21A and SN74LV21A are dual 4‑input positive‑AND gates designed for 2 V to 5.5 V VCC operation. They implement the Boolean function Y = A·B·C·D in positive logic and support partial‑power‑down mode to prevent back‑flow current when powered down.
The datasheet provides absolute maximum ratings, recommended operating conditions, electrical and switching characteristics, noise performance, and detailed package options (D, DB, DGV, J, NS, PW, W). Ordering information, mechanical dimensions, and packaging material specifications are also included.
They perform the Boolean function Y = A·B·C·D (positive logic).
The device is offered in D, DB, DGV, J, NS, PW and W packages.
