Nexperia USA Inc. 74AHCT1G86GW,165

Overview

74AHCT1G86GW,165 from Nexperia is a single 2-input EXCLUSIVE-OR gate in TSSOP5 (SOT353-1) package, designed for level translation between TTL and CMOS logic domains. It operates from 4.5 V to 5.5 V, features overvoltage-tolerant inputs up to 5.5 V, delivers propagation delay as low as 3.5 ns (typical at VCC = 5.0 V, CL = 15 pF), and is rated for industrial temperature range (–40 °C to +125 °C). It is used in digital signal routing, parity generation, and mixed-voltage interface circuits.

For engineers reviewing the 74AHCT1G86GW,165 datasheet, 74AHCT1G86GW,165 pinout, 74AHCT1G86GW,165 application, or 74AHCT1G86GW,165 equivalent, this page provides verified functional identity, validated pin mapping, confirmed operating margins, and real-world use context - all derived from Nexperia's official Rev. 8 product data sheet dated 16 January 2026.

Technical Context

This device implements standard XOR logic (Y = A ⊕ B) with TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V) and rail-to-rail CMOS output drive. Its symmetrical output impedance ensures matched rise/fall times, and balanced propagation delays support timing-critical combinational logic paths.

Input overvoltage tolerance enables direct interfacing with 5.5 V signals even when powered at 4.5 V, eliminating external level-shifting components. The device meets JESD 78 Class II Level A latch-up immunity (>100 mA) and JEDEC JS-001/JS-002 ESD specifications (HBM >2000 V, CDM >1000 V).

The following parts are listed as comparable options for similar 2-input XOR gate applications.

Compared with 74AHCT1G86GW,165, the LVC variants offer broader supply flexibility and lower power but sacrifice overvoltage tolerance and extended temperature rating - making them unfit for mixed-voltage industrial interfaces where robustness and thermal resilience are mandatory.

FAQ

What is the maximum input voltage the 74AHCT1G86GW,165 can tolerate?

The device supports input voltages up to 5.5 V independent of VCC, as confirmed in Section 8 (Limiting Values) and Section 2 (Features) of the Rev. 8 datasheet. This overvoltage tolerance applies to all inputs (A, B) and remains valid even when VCC is as low as 4.5 V - enabling safe interfacing with higher-voltage signal sources without external protection.

Can the 74AHCT1G86GW,165 operate at 3.3 V supply?

No. Per Table 6 (Recommended Operating Conditions), the 74AHCT variant requires VCC between 4.5 V and 5.5 V. At 3.3 V, input thresholds (VIH ≥ 2.0 V) would not be met reliably, and output drive strength degrades significantly. For 3.3 V systems, select the 74AHC1G86GW or 74LVC1G86 variants instead.

Is the 74AHCT1G86GW,165 pin-compatible with other 5-pin logic gates in TSSOP5?

Yes - it shares the SOT353-1 (TSSOP5) footprint and identical pinout (1=B, 2=A, 3=GND, 4=Y, 5=VCC) with Nexperia's 74AHCT1Gxx series (e.g., 74AHCT1G00, 74AHCT1G08). This allows drop-in replacement in layouts designed for standard 5-lead logic gates without PCB revision.

Does the 74AHCT1G86GW,165 require external pull-up or pull-down resistors on unused inputs?

Yes. Unused inputs must be terminated to VCC or GND to prevent floating nodes, which cause increased ICC, erratic output behavior, and potential ESD vulnerability. The datasheet does not integrate internal biasing; Section 6.2 explicitly defines A and B as "data inputs" with no weak pull-up/pull-down specification.
