SN7400NSRE4

Overview

The SN7400NSRE4 is a quadruple 2-input positive-NAND gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a commercial temperature range from 0°C to +70°C. The device features four independent NAND gates, each with two inputs, housed in a 14-pin TSSOP package. Key electrical characteristics include a low-level output current of 16 mA and a high-level output current of -400 µA. The propagation delay is specified at 11 ns.

Feature Summary

Integrates four independent 2-input NAND logic gates for complex digital circuit design
Provides robust low-level sink current capability for driving loads
Compatible with standard 5V TTL logic families

Applications

Digital logic signal processing
Microcontroller input/output interfacing
General-purpose switching circuits

Procurement Notes

Verify the specific suffix 'SRE4' corresponds to the TSSOP-14 package and tape-and-reel packaging configuration. Confirm RoHS compliance status as indicated by the E4 suffix. Ensure the operating temperature range meets the application requirements. Cross-reference the manufacturer part number with official TI documentation to confirm pinout and electrical specifications match the intended design.

Selection Notes

Select this component when a quad 2-input NAND function is required in a surface-mount TSSOP-14 package. It serves as a direct replacement for other SN7400 variants with compatible pinouts. Consider the propagation delay and output drive strength relative to the system speed requirements. Verify that the 5V logic level compatibility aligns with the surrounding circuitry.

Part Context

The SN7400 series represents a foundational family of quadruple 2-input NAND gates widely used in digital electronics. The SN7400NSRE4 variant specifically utilizes Texas Instruments' lead-free manufacturing process and surface-mount packaging technology. This component belongs to the standard 7400 logic family, ensuring broad compatibility with existing digital designs and legacy systems requiring NAND logic functionality.
