SN74LS20DR

Inverter Gates Overview

The SN74LS20DR is a dual four-input NAND gate integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 4.75V to 5.25V and features two independent logic channels, each with four inputs. The device utilizes a 14-SOIC surface-mount package and supports propagation delays of up to 15ns at 5V with 15pF load. It maintains low-level output current of 400µA and high-level output current of 8mA, with a maximum static current of 800µA.
