Nexperia USA Inc. 74AHC1G86GW,125

Overview

74AHC1G86GW,125 from Nexperia is a single 2-input CMOS EXCLUSIVE-OR gate in TSSOP5 (SOT353-1) package, operating from 2.0 V to 5.5 V supply, with overvoltage-tolerant inputs up to 5.5 V, symmetrical output impedance, and guaranteed operation from –40 °C to +125 °C. It serves as a level-translating logic gate in mixed-voltage digital interfaces such as I²C pull-up domain bridging or sensor signal conditioning.

For engineers reviewing the 74AHC1G86GW,125 datasheet, 74AHC1G86GW,125 pinout, 74AHC1G86GW,125 application, or 74AHC1G86GW,125 equivalent, this device is selected for low-power, high-noise-immunity XOR functions in space-constrained industrial control modules, automotive body electronics, and portable instrumentation where input voltage translation between 3.3 V and 5 V domains is required.

Technical Context

This device implements standard two-input XOR Boolean logic (Y = A ⊕ B) using advanced AHC CMOS process technology. Its overvoltage-tolerant inputs enable direct interfacing with 5.5 V signals while powered from as low as 2.0 V, eliminating external level shifters in mixed-supply systems.

Propagation delays are tightly balanced (tPLH ≈ tPHL), with typical values of 3.4 ns at VCC = 5.0 V and CL = 15 pF. Static characteristics include VIH = 3.85 V (min) and VOL = 0.36 V (max) at IO = 8.0 mA, ensuring robust noise margins across full temperature range.

FAQ

Is 74AHC1G86GW,125 pin-compatible with 74AHCT1G86GW,125?

Yes - both share identical TSSOP5 (SOT353-1) pinout, thermal profile, and package dimensions. The only functional difference is input threshold: AHC uses CMOS-level inputs (VIH ≥ 3.85 V at VCC = 5.5 V), while AHCT uses TTL-level inputs (VIH ≥ 2.0 V). No PCB change is needed for substitution, but verify source logic family compatibility.

What is the maximum capacitive load this device can drive reliably?

The device is characterized up to 50 pF load capacitance, with propagation delay specified at CL = 15 pF and CL = 50 pF. At VCC = 5.0 V, tpd remains ≤8.5 ns (max) even at 50 pF. For loads exceeding 50 pF, add series termination or buffer stages to maintain signal integrity and timing margins.

Does this part support partial power-down or I/O isolation when VCC = 0 V?

No - the device lacks I/O protection during power-off. When VCC = 0 V, inputs remain overvoltage-tolerant up to 5.5 V, but outputs enter high-impedance state only after power removal; residual current paths may exist. For true I/O isolation, use dedicated bus-hold or power-switching ICs upstream.

Can 74AHC1G86GW,125 operate at 1.8 V supply?

No - the absolute minimum supply voltage is 2.0 V per datasheet Section 9. Operation below 2.0 V risks undefined logic states, increased propagation delay, and failure to meet VIH/VIL thresholds. For 1.8 V systems, consider SN74LVC1G86 or 74LVC1G86 variants explicitly rated down to 1.65 V.
