Overview
The SN74AHCT86RGYRG4 is a quadruple 2-input exclusive-OR gate from the Texas Instruments SNx4AHCT86 family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -40°C to +125°C. The device features TTL-compatible inputs with specified high-level input voltage (VIH) of 2 V and low-level input voltage (VIL) of 0.8 V. Electrical characteristics include a maximum propagation delay of 9 ns at 50 pF load capacitance, balanced output drive currents of ±8 mA, and a typical power dissipation capacitance of 18 pF.
Feature Summary
- TTL-voltage compatible inputs allow for direct interface with legacy logic standards.
- Low-drive CMOS architecture minimizes output ringing and overshoot on bus interfaces.
- ESD protection exceeds JESD 22 standards with 2000-V Human-Body Model tolerance.
Applications
- Server systems
- Network switches
- Telecom infrastructures
Procurement Notes
Verify the specific ordering suffix 'RGYRG4' corresponds to the VQFN package and lead finish requirements. Confirm moisture sensitivity level (MSL) ratings align with your reflow soldering profile. Ensure the component status is listed as active production rather than obsolete or preproduction before finalizing procurement plans.
Selection Notes
Select this component when TTL compatibility is required alongside modern CMOS performance. The RGY package offers a compact footprint suitable for space-constrained designs. Verify that the 5 V supply voltage requirement matches your system architecture, as the device does not support lower voltage operation.
Part Context
This part belongs to the SNx4AHCT86 series of quadruple 2-input exclusive-OR gates. The RGY suffix indicates a 14-pin VQFN package variant. The G4 suffix denotes compliance with environmental directives. The device implements the Boolean function Y = A × B in positive logic.
