Overview
The SN74AHCT00NSR is a quadruple 2-input positive-NAND gate from the Texas Instruments SN74AHCT00 series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a TSSOP-14 package. The device provides four independent NAND gates with eight inputs and four outputs. Key electrical parameters include a propagation delay of 5.5 ns, low-level output current of 8 mA, and high-level output current of -8 mA. It supports surface mount installation and functions reliably across an operating temperature range of -55°C to +125°C.
Feature Summary
- Contains four independent 2-input NAND logic gates for complex digital circuit implementation
- Compatible with standard TTL input levels while utilizing CMOS technology
- Designed for high-speed signal processing with specified propagation delay characteristics
Applications
- Digital logic control systems requiring NAND functionality
- Signal gating and switching applications in industrial equipment
- Data acquisition systems interfacing with microcontrollers
Procurement Notes
Verify the specific suffix NSR indicates the tape-and-reel packaging format compatible with automated surface-mount assembly processes. Confirm that the SN74AHCT00NSR designation aligns with the required TSSOP-14 package dimensions and pinout configuration for your PCB layout. Ensure the component meets the necessary RoHS compliance standards for your manufacturing region. Cross-reference the manufacturer part number against official datasheets to validate the exact electrical specifications and thermal performance ratings before finalizing procurement orders.
Selection Notes
Select this component when a quad 2-input NAND gate is required with compatibility to TTL logic levels. The AHCT series is suitable for designs needing operation at 5V with robust noise immunity. Consider the TSSOP-14 package if space constraints favor surface-mount technology over through-hole alternatives. Evaluate the -55°C to +125°C temperature range against your environmental operating conditions to ensure reliability under extreme thermal stress scenarios.
Part Context
This component belongs to the SN74AHCT00 family of single-function logic gates manufactured by Texas Instruments. The AHCT series bridges the gap between older TTL logic families and modern CMOS technologies, offering improved power consumption and speed. The SN74AHCT00NSR specifically denotes the non-commercial grade version packaged in a reel for high-volume surface-mount production lines.
