74HCT1G86GW,125

Overview

The Nexperia 74HCT1G86GW,125 is a single 2-input EXCLUSIVE-OR gate housed in a TSSOP5 (SOT353-1) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL input levels, CMOS low power dissipation, and high noise immunity. Static characteristics include a maximum supply current of 20 µA at 5.5 V. Dynamic performance specifies a propagation delay of up to 27 ns at 4.5 V with 50 pF load capacitance.

Feature Summary

• Provides exclusive-OR logic functionality with balanced propagation delays
• Features inputs compatible with TTL logic levels for direct interfacing
• Includes clamp diodes on inputs to allow operation with voltages exceeding VCC when using current limiting resistors

Applications

• Digital signal processing circuits requiring XOR operations
• Logic level translation between mixed voltage systems
• General purpose digital logic applications

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the HCT series designation aligns with the target system's TTL input requirements rather than standard HC CMOS levels. Ensure the operating environment remains within the specified -40 °C to +125 °C temperature range to maintain guaranteed electrical parameters.

Selection Notes

Select this component when a single XOR gate is needed with TTL-compatible inputs. The TSSOP5 package offers a compact surface-mount solution suitable for space-constrained designs. Consider the 27 ns propagation delay limit for timing-sensitive paths. Verify that the 5.5 V maximum supply voltage meets the design constraints.

Part Context

This part belongs to the Nexperia 74HCT1Gxx family of single-function gates. It shares the same logical function as the 74HC1G86 but utilizes HCT technology for TTL compatibility. The GW suffix specifically denotes the TSSOP5 plastic thin shrink small outline package with five leads.

Replacement Considerations

The 74HC1G86GW,125 serves as a functional substitute if the application can accommodate CMOS input levels instead of TTL levels.
