Overview
The SN74ACT00NSR is a quadruple 2-input positive-NAND gate from the Texas Instruments SN74ACT series. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs with CMOS outputs. The device provides low-level output current of 24 mA and high-level output current of -24 mA, with a typical propagation delay of 9.5 ns. Designed for surface-mount applications, it is housed in an SOIC-14 package and supports industrial temperature ranges.
Feature Summary
- Integrates four independent 2-input NAND logic gates in a single package
- Features TTL-compatible input thresholds for direct interfacing with TTL logic systems
- Provides robust drive capability with 24 mA sink and source output currents
- Operates reliably across extended industrial temperature ranges
Applications
- General-purpose digital logic signal processing
- Data acquisition system input conditioning
- Microcontroller peripheral interface gating
- Memory address decoding circuits
Procurement Notes
Verify the specific suffix NSR indicates the SOIC-14 surface mount package configuration. Confirm the ACT logic family designation matches the required 4.5V to 5.5V operating voltage window. Ensure the manufacturer is Texas Instruments to guarantee specified electrical characteristics and reliability standards are met for the design.
Selection Notes
Select this component when TTL-compatible inputs are required alongside CMOS output drive capabilities. The SN74ACT00NSR is suitable for designs needing moderate speed performance with standard noise margins. Consider the SOIC-14 footprint constraints and ensure the application voltage remains strictly within the 4.5V to 5.5V operational limits defined by the datasheet specifications.
Part Context
This part belongs to the SN74ACT logic family, which bridges the gap between older TTL standards and modern CMOS technology. It offers improved switching speeds compared to legacy LS variants while maintaining backward compatibility with existing TTL input levels. The series is widely used in general-purpose digital electronics requiring reliable logic inversion functions.
Replacement Considerations
SN74ACT00N is a pin-compatible through-hole alternative. SN74AHC00NSR offers similar functionality with lower voltage operation. SN74ACT00NE4 is a lead-free variant of the DIP package.
