Nexperia USA Inc. 74HC2G86DC,125

Overview

74HC2G86DC,125 from Nexperia is a dual 2-input EXCLUSIVE-OR gate in VSSOP8 (SOT765-1) package, operating from 2.0 V to 6.0 V supply, delivering propagation delay as low as 9.0 ns at VCC = 6.0 V and 11 ns at 4.5 V, with ±20 mA output drive capability and -40 °C to +125 °C temperature rating - used in digital logic arbitration, parity generation, and signal-level XOR mixing in industrial control interfaces.

For engineers reviewing the 74HC2G86DC,125 datasheet, 74HC2G86DC,125 pinout, 74HC2G86DC,125 application, or 74HC2G86DC,125 equivalent, key selection criteria include CMOS input compatibility, dual-gate integration in sub-3 mm body width, guaranteed timing performance across full industrial temperature range, and compliance with JESD7A/JESD8C voltage standards.

Technical Context

This device implements two independent XOR logic functions in a single monolithic CMOS IC, with inputs featuring integrated clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Each gate exhibits symmetrical propagation delays for both rising and falling edges (tPLH = tPHL).

It supports mixed-voltage system interfacing via configurable input thresholds: 74HC2G86DC accepts CMOS-level inputs (VIH ≥ 0.7×VCC), while its HCT variant uses TTL-compatible thresholds (VIH = 2.0 V min at VCC = 4.5–5.5 V). Output stages are designed for rail-to-rail swing with VOH ≥ 4.18 V and VOL ≤ 0.26 V at IO = ±4.0 mA.

FAQ

What is the maximum recommended supply voltage for continuous operation?

The absolute maximum supply voltage is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V. Operation above 6.0 V risks exceeding static and dynamic power limits, especially at elevated temperatures, and violates JEDEC JESD7A compliance. Sustained use at 6.5 V may cause accelerated parametric drift or latch-up under transient conditions.

Can 74HC2G86DC,125 interface directly with 5 V TTL outputs?

No - the 74HC2G86DC variant has CMOS input thresholds (VIH ≥ 0.7×VCC), so at VCC = 5 V, VIH min = 3.5 V, which is insufficient for standard TTL VOH (2.4 V min). Use the 74HCT2G86DC variant instead, whose VIH is specified at 2.0 V min for VCC = 4.5–5.5 V, ensuring reliable recognition of TTL logic highs.

Is the VSSOP8 package RoHS and REACH compliant?

Yes - the SOT765-1 package used for 74HC2G86DC,125 is lead-free, halogen-free, and fully compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Nexperia's material declarations confirm absence of SVHC substances above threshold limits and full conformity with Annex XIV sunset provisions.

How does input clamping affect external resistor selection?

Clamp diodes conduct when input voltage falls below GND −0.5 V or rises above VCC + 0.5 V. To limit clamp current to ≤±20 mA, series resistors must be ≥|(VIO − VCC)/20 mA| for overvoltage cases. For example, interfacing a 12 V signal to VCC = 5 V requires R ≥ (12 − 5.5)/0.02 = 325 Ω minimum; 1 kΩ is typical for margin and noise filtering.
