Overview
The SN74AHC1G86DBVRG4 is a single-channel, dual-input exclusive-OR (XOR) gate manufactured by Texas Instruments. It belongs to the AHC logic family and utilizes CMOS technology. The device operates within a supply voltage range of 2 V to 5.5 V. It features low input capacitance and high noise immunity. The component is housed in a SOT-23-5 surface-mount package. It supports an operating temperature range from -40°C to +125°C. Propagation delay is typically 7.9 ns at 5 V with 50 pF load.
Feature Summary
- Single-channel XOR logic function for signal comparison
- Wide operating voltage range supporting 2V to 5.5V systems
- High noise immunity and low power consumption characteristics
- Compact SOT-23-5 surface-mount packaging
Applications
- Digital data path switching and routing
- Parity generation and error detection circuits
- Logic level translation between different voltage domains
- Arithmetic logic unit (ALU) components
Procurement Notes
Verify the complete part number including the G4 suffix to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm the specific tape-and-reel quantity matches the production requirements. Check for moisture sensitivity level classifications prior to soldering. Ensure storage conditions adhere to recommended humidity controls to prevent package damage before reflow processing.
Selection Notes
Select this component when a single XOR gate is required in a space-constrained design. The AHC series offers faster switching speeds compared to standard HC logic while maintaining lower power dissipation. The wide voltage range allows compatibility with both 3.3V and 5V logic families. Consider the SOT-23-5 footprint constraints during PCB layout planning.
Part Context
This device is part of Texas Instruments' SN74AHC1Gxx series of single-gate logic ICs. It provides a compact alternative to multi-gate packages like the SN74AHC86. The G4 suffix indicates environmental compliance. It serves as a building block for complex digital logic functions requiring exclusive-OR operations in portable and battery-powered applications.
Replacement Considerations
The SN74AHC1G86DBVR is a compatible non-G4 variant. The SN74AHCT1G86DBVR offers TTL-compatible input thresholds but requires a 4.5V to 5.5V supply. Verify pinout compatibility and electrical specifications before substitution.
