Nexperia USA Inc. 74AHC1G86GW,165

Overview

74AHC1G86GW,165 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 and guaranteed operation from –40 °C to +125 °C. It delivers symmetrical output impedance, balanced propagation delays (typ. 3.4 ns at 5 V, 15 pF), and supports voltage-level translation in mixed-supply systems.

For engineers reviewing the 74AHC1G86GW,165 datasheet, 74AHC1G86GW,165 pinout, 74AHC1G86GW,165 application, or 74AHC1G86GW,165 equivalent, this device serves as a low-power, high-noise-immunity logic gate for digital signal conditioning, parity generation, and interface-level translation in industrial control, sensor interfaces, and embedded microcontroller peripheral logic.

Technical Context

This device implements a standard XOR Boolean function (Y = A ⊕ B) with true TTL-compatible input thresholds only in the AHCT variant; the AHC version uses CMOS-level inputs (VIH ≥ 3.85 V at VCC = 5.5 V). Its overvoltage-tolerant inputs enable safe interfacing between 3.3 V logic domains and 5 V buses without external level shifters.

Dynamic performance is characterized by matched tPLH/tPHL propagation delays (≤ 8.5 ns max at VCC = 5.5 V, CL = 15 pF), low power dissipation capacitance (CPD = 9 pF), and rail-to-rail output swing. Static drive strength is specified at ±8 mA output current with VOL ≤ 0.36 V and VOH ≥ 3.94 V under load at 4.5 V supply.

FAQ

Is the 74AHC1G86GW,165 pin-compatible with the 74AHCT1G86GW,165?

Yes - both share identical TSSOP5 (SOT353-1) pinout, package dimensions, and terminal numbering. The only functional difference lies in input threshold levels: AHC requires CMOS-compatible VIH (≥3.85 V at 5.5 V), while AHCT accepts TTL-level VIH (≥2.0 V). No PCB redesign is needed for substitution.

Can this device safely translate between 3.3 V and 5 V logic domains?

Yes - its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC, enabling direct connection from a 5 V source to a 3.3 V-powered 74AHC1G86GW,165. Output swing remains rail-to-rail (0 V to VCC), so a 3.3 V supply yields 0–3.3 V output compatible with downstream 3.3 V receivers.

What is the maximum capacitive load this gate can drive while maintaining timing specs?

The datasheet specifies timing parameters up to 50 pF load capacitance. At CL = 50 pF and VCC = 5.0 V, tpd is guaranteed ≤ 8.5 ns. Driving >50 pF will increase propagation delay nonlinearly and may cause marginal setup/hold timing in synchronous systems; add a buffer for loads exceeding 60 pF.

Does this part require external pull-up or pull-down resistors on unused inputs?

No - unused inputs must be terminated to a defined logic level (VCC or GND) to prevent floating states that increase dynamic power and risk oscillation. Internal protection diodes and CMOS structure do not provide reliable default biasing; a 10 kΩ resistor to VCC or GND is recommended for each unterminated input.
