Nexperia USA Inc. 74LVC2G86DP,125

Overview

74LVC2G86DP,125 from Nexperia is a dual 2-input XOR gate logic IC operating from 1.65 V to 5.5 V, featuring Schmitt-trigger inputs for noise immunity and IOFF circuitry enabling partial power-down mode. It supports mixed-voltage interfacing (3.3 V/5 V), delivers ±24 mA output drive at 3.0 V, and is rated for operation from −40 °C to +125 °C in TSSOP8 (SOT505-2) package.

For engineers reviewing the 74LVC2G86DP,125 datasheet, 74LVC2G86DP,125 pinout, 74LVC2G86DP,125 application, or 74LVC2G86DP,125 equivalent, key selection criteria include voltage translation capability between 3.3 V and 5 V domains, IOFF-enabled system-level power sequencing, Schmitt-trigger input hysteresis for slow-edge signal conditioning, and guaranteed performance across industrial and extended temperature ranges.

Technical Context

This device implements two independent XOR logic functions with fully buffered CMOS outputs. Each gate accepts inputs tolerant up to 5.5 V regardless of supply voltage, enabling bidirectional level shifting without external components. The Schmitt-trigger inputs provide 0.3 V typical hysteresis, improving noise rejection on noisy or slowly transitioning signals.

The IOFF feature disables outputs when VCC = 0 V, blocking backflow current during hot-insertion or partial power-down sequences. Input leakage remains ≤±1 μA and power-off leakage ≤±2 μA over full temperature range, ensuring robustness in multi-rail systems requiring controlled power sequencing.

FAQ

Can the 74LVC2G86DP,125 operate reliably with a 1.8 V supply?

Yes. The device is fully specified from 1.65 V to 5.5 V, with VIH minimum of 0.65×VCC (1.17 V at 1.8 V) and VIL maximum of 0.35×VCC (0.63 V at 1.8 V). Propagation delay is 3.8 ns typical at 1.8 V, and output drive remains functional at ±4 mA, making it suitable for 1.8 V FPGA I/O banks and low-power microcontroller peripherals.

Does the IOFF feature require external circuitry to function?

No. IOFF is fully internal and activates automatically when VCC drops to 0 V. Output terminals enter high-impedance state without pull-up/down resistors or control signals. Measured IOFF leakage is ≤±2 μA at 5.5 V applied to inputs/outputs while VCC = 0 V, satisfying IEC 61000-4-2 system-level ESD immunity requirements.

What is the maximum capacitive load the 74LVC2G86DP,125 can drive at 3.3 V?

At VCC = 3.3 V, the device maintains guaranteed VOL ≤0.55 V and VOH ≥2.62 V while sourcing/sinking 24 mA. With typical CPD = 15.8 pF per gate and tpd = 2.3 ns (typ), it reliably drives ≤50 pF total load (including trace and input capacitance) while meeting setup/hold timing in 100 MHz synchronous logic paths.

How does the Schmitt-trigger input improve noise immunity compared to standard CMOS inputs?

Schmitt-trigger inputs provide ~0.3 V hysteresis (difference between VIH and VIL thresholds), preventing multiple output transitions caused by slow-rising or noisy input signals. At VCC = 3.3 V, VIH ≈2.0 V and VIL ≈0.8 V - meaning an input crossing 2.0 V triggers HIGH, but must fall below 0.8 V to register LOW, rejecting noise spikes within that window.
