Nexperia USA Inc. 74HC2G86DP,125

Overview

74HC2G86DP from Nexperia is a dual 2-input EXCLUSIVE-OR gate in TSSOP8 package, operating from 2.0 V to 6.0 V supply, delivering propagation delay as low as 9.0 ns at 6.0 V and supporting industrial temperature range up to +125 °C. It features CMOS-level inputs, ±20 mA clamping current capability, and is used in digital logic arbitration, parity generation, and signal comparison circuits.

For engineers reviewing the 74HC2G86DP datasheet, 74HC2G86DP pinout, 74HC2G86DP application, or 74HC2G86DP equivalent, this device serves as a low-power, high-noise-immunity XOR logic building block for embedded control, interface translation, and data path conditioning where precise timing and rail-to-rail compatibility are required.

Technical Context

This device implements two independent XOR gates with fully buffered outputs and input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Each gate exhibits symmetrical propagation delay (tPLH = tPHL) and transition time (tTLH = tTHL), ensuring predictable timing behavior across temperature and voltage.

The logic function follows standard XOR truth table (L/L→L, L/H→H, H/L→H, H/H→L), with VIH/VIL thresholds defined per supply voltage - e.g., VIH ≥ 4.2 V at VCC = 6.0 V for HC version - and output drive strength rated at ±4.0 mA for VOH/VOL compliance under load.

FAQ

What is the maximum clock frequency supported by 74HC2G86DP?

The device does not operate on a clock; it is combinational logic. Its usable toggle rate depends on propagation delay and load. With 10 pF load and VCC = 6.0 V, tpd = 9.0 ns (typ), enabling reliable operation up to ~50 MHz for repetitive XOR patterns. System-level timing must account for input rise/fall times and output loading.

Can 74HC2G86DP interface directly with 3.3 V microcontroller GPIOs?

Yes. At VCC = 3.3 V, VIH(min) = 2.1 V and VIL(max) = 1.35 V per datasheet Table 7, matching standard 3.3 V CMOS logic levels. Outputs swing rail-to-rail (VOH ≥ 3.15 V, VOL ≤ 0.26 V at 4 mA), ensuring noise margins > 0.7 V in typical PCB environments.

Is thermal derating required for continuous operation at +125 °C?

Yes. For SOT505-2 package, total power dissipation derates linearly at 4.6 mW/K above 96 °C. At +125 °C, maximum allowed Ptot drops to ~130 mW (250 mW − 4.6 mW/K × 29 K). This supports typical logic operation (<10 mW) but limits simultaneous high-speed switching across both gates under heavy capacitive load.

Does 74HC2G86DP support hot-swap or live-insertion?

No. The device lacks powered-off protection circuitry. Applying input signals before VCC stabilization risks forward-biasing internal clamp diodes, causing excessive current flow. Always ensure VCC is stable and within specification before applying inputs - use power sequencing controllers in hot-swap systems.
