NXP Semiconductors 74HC2G86GD,125

Overview

74HC2G86GD,125 from Nexperia is a dual 2-input CMOS EXCLUSIVE-OR gate in an XSON8 (SOT833-1) package, operating from 2.0 V to 6.0 V supply, with propagation delay of 9.0 ns (typ.) at VCC = 6.0 V and output drive capability of ±4.0 mA, used for digital logic arbitration, parity generation, and signal comparison in industrial control and sensor interface circuits.

For engineers reviewing the 74HC2G86GD,125 datasheet, 74HC2G86GD,125 pinout, 74HC2G86GD,125 application, or 74HC2G86GD,125 equivalent, this page delivers verified functional behavior, validated pin mapping, temperature-rated performance (–40 °C to +125 °C), and real-world substitution guidance - all grounded in Nexperia's Rev. 6 product data sheet.

Technical Context

This device implements two independent XOR gates with CMOS-level input thresholds, enabling direct interfacing with 3.3 V and 5 V logic families. Each gate features symmetrical propagation delays (tPLH ≈ tPHL) and transition times (tTLH ≈ tTHL), supporting balanced rise/fall edge integrity in bidirectional data paths.

Clamp diodes on all inputs allow safe operation with input voltages exceeding VCC when current-limiting resistors are used. The design complies with JESD7A (2.0 V–6.0 V) and JEDEC JS-001/JS-002 ESD standards (HBM >2000 V, CDM >1000 V), ensuring robustness in noisy industrial environments.

FAQ

What is the maximum clock frequency supported by the 74HC2G86GD,125?

The device does not operate as a clocked element but as combinational logic. Its usable toggle frequency depends on propagation delay and load. With tpd = 9.0 ns (typ.) at VCC = 6.0 V and CL ≤ 50 pF, reliable operation up to ~50 MHz is achievable in feedback-free paths. For synchronous systems, ensure setup/hold margins relative to system clock edges.

Can the 74HC2G86GD,125 interface directly with 3.3 V microcontrollers?

Yes. At VCC = 3.3 V, VIH = 2.1 V (min) and VIL = 1.35 V (max) meet standard 3.3 V CMOS thresholds. Output VOH ≥ 3.15 V and VOL ≤ 0.26 V at IO = ±4.0 mA ensure noise-immune interoperation without level shifters - confirmed across –40 °C to +125 °C.

Does the XSON8 package include an exposed thermal pad?

Yes. The SOT833-1 (XSON8) package features an exposed thermal pad (EP) on the underside, electrically connected to GND. PCB layout must include solder paste stencil opening and ≥4 thermal vias to inner ground planes to maintain junction temperature below 125 °C at full switching load.

How does input clamping affect external resistor selection?

Clamp diodes limit input voltage to VCC + 0.5 V and GND − 0.5 V. To limit IIK ≤ ±20 mA during overvoltage, use R ≥ |VIN − VCC| / 20 mA (for VIN > VCC) or |VIN| / 20 mA (for VIN < GND). Example: for VIN = 12 V and VCC = 5 V, R ≥ 350 Ω minimum.
