SN7400NSR

Overview

The SN7400NSR is a quad 2-input NAND gate integrated circuit manufactured by Texas Instruments. It utilizes standard CMOS technology and operates within a supply voltage range of 2V to 6V. The device features push-pull outputs with maximum low-level output current of 5.2mA and maximum high-level output current of -5.2mA. Propagation delay varies based on supply voltage, reaching 15ns at 6V, 18ns at 4.5V, and 90ns at 2V. It is housed in a 14-pin Small Outline Package (SOP) and supplied in tape and reel format.

Feature Summary

• Contains four independent 2-input NAND logic gates
• CMOS process technology for low power consumption
• Push-pull output configuration
• Wide operating supply voltage range

Applications

• General-purpose digital logic circuits
• Signal gating and switching applications
