SNJ54LS20FK TI Logic Gates | Dual 4-Input NAND | Military Temp, -55 to +125°C

Product Overview

The SNJ54LS20FK is a dual 4-input NAND gate from Texas Instruments, part of the 54LS series designed for military and high-reliability applications. It operates over the full military temperature range of -55°C to +125°C and is available in a ceramic flat package (FK). This device provides the logic function Y = A·B·C·D with two independent gates, each with four inputs. It features low power consumption typical of LS logic, with a propagation delay of 15 ns and a fan-out of 10 LS loads. The SNJ54LS20FK is ideal for use in harsh environments where reliability and performance are critical.
