Overview
The SN74H87N3 is a high-speed CMOS quad exclusive-OR gate manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and features low power consumption typical of the H-series logic family. The device utilizes a 14-pin DIP package, providing four independent XOR gates for digital logic applications. It offers improved switching speeds compared to standard TTL equivalents while maintaining compatibility with existing system architectures.
Feature Summary
- High-speed operation suitable for complex digital systems
- Low power dissipation characteristics inherent to CMOS technology
- Quad configuration provides multiple independent logic functions in a single package
Applications
- Digital arithmetic circuits requiring parity generation or checking
- Data comparison logic in microprocessor interfaces
- Error detection mechanisms in communication systems
Procurement Notes
Verify the specific manufacturer marking and date code on the component body to ensure authenticity. Confirm that the package type matches the required footprint for your PCB design. Check for any RoHS compliance documentation if environmental regulations apply to your manufacturing process. Ensure storage conditions prevent electrostatic discharge damage prior to installation.
Selection Notes
Select this component when a compact solution for multiple XOR operations is needed in low-power environments. Consider the operating voltage range to ensure compatibility with your system's power rails. Evaluate pin count requirements against other available packages if space constraints exist. Verify signal integrity needs against the specified propagation delays for your clock frequencies.
Part Context
This part belongs to the Texas Instruments SN74H series, which represents high-speed CMOS logic. The 'N' suffix typically denotes a plastic dual-in-line package variant. This series bridges the performance gap between older TTL technologies and modern ultra-low-power CMOS options, offering a balance of speed and efficiency for general-purpose digital logic tasks.
Replacement Considerations
Compatible substitutes include the SN74HCT87N for TTL-compatible input levels or the SN74HC87N for broader voltage ranges. Verify pinout compatibility before substitution. Ensure electrical characteristics such as input threshold voltages match your circuit requirements to avoid logic errors.
