Overview
The SN7400NE4 is a standard plastic DIP-14 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 an operating temperature range of 0°C to 70°C. The device features TTL-compliant inputs with a high-level input voltage (VIH) of 2 V and a low-level input voltage (VIL) of 0.8 V, allowing compatibility with 3.3-V or 2.5-V logic inputs. Electrical characteristics include a maximum low-level output current (IOL) of 16 mA and a typical propagation delay of 15 ns at 5 V.
Feature Summary
- Contains four independent 2-input NAND gates performing the Boolean function Y = A.B in positive logic.
- Inputs are TTL compliant and can accept 3.3-V or 2.5-V logic inputs.
- Available in standard plastic DIP package options.
Applications
- AV Receivers
- Portable Audio Docks
- Blu-Ray Players
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type, lead finish, and environmental compliance status. Ensure the selected variant matches the required operating temperature range and pin configuration for your design implementation.
Selection Notes
Select this component when a standard quad 2-input NAND gate is required for general-purpose digital logic applications. Consider the PDIP-14 package for through-hole mounting requirements and verify that the 0°C to 70°C commercial temperature range meets the system's operational environment specifications.
Part Context
This part belongs to the SNx4xx00 family of quadruple 2-input positive-NAND gates produced by Texas Instruments. The family includes variants such as SN5400, SN54LS00, SN54S00, SN74LS00, and SN74S00, which differ in speed, power consumption, and military-grade temperature ratings while maintaining similar logical functionality.
Replacement Considerations
Compatible substitutes include SN7400N, SN7400D, and SN74LS00N. Verify pinout compatibility and electrical parameter alignment before substitution.
FAQ
Can the SN7400NE4 accept 3.3-V logic inputs?
Yes, the inputs are TTL compliant and can accept 3.3-V or 2.5-V logic inputs.
What is the recommended bypass capacitor value for the power supply?
A 0.1 µF bypass capacitor is recommended for devices with a single supply, placed as close to the power pin as possible.
