Nexperia USA Inc. 74LV1T86GXH

Overview

74LV1T86GXH from Nexperia is a single-supply, level-translating 2-input XOR gate in X2SON5 (SOT1226-3) package, supporting bidirectional voltage translation between 1.2 V–5.0 V logic domains. It features 5 V-tolerant inputs, operates from −40 °C to +125 °C, and delivers propagation delays as low as 3.4 ns (VCC = 5.0 V, CL = 15 pF), enabling use in mixed-voltage I/O interfacing for portable MCU peripherals.

For engineers reviewing the 74LV1T86GXH datasheet, 74LV1T86GXH pinout, 74LV1T86GXH application, or 74LV1T86GXH equivalent, key selection criteria include its single-supply translation capability, 5 V input tolerance, guaranteed operation across 1.6 V–5.5 V supply range, and thermal-enhanced X2SON5 footprint for space-constrained PCBs.

Technical Context

The 74LV1T86GXH implements a CMOS-based XOR logic function with input thresholds dynamically scaled to VCC, enabling reliable up-translation (e.g., 1.8 V inputs → 3.3 V outputs at VCC = 3.3 V) and down-translation (e.g., 5.0 V inputs → 3.3 V outputs at VCC = 3.3 V). Its 5 V-tolerant inputs eliminate external clamping diodes when interfacing legacy 5 V signals.

Static behavior is characterized by VIH/VIL thresholds that scale with VCC (e.g., VIH ≥ 0.65 × VCC at VCC = 3.0–3.6 V), while output drive strength supports ±5.5 mA at VCC = 3.3 V and ±8 mA at VCC = 4.5 V, ensuring robust signal integrity into 15–30 pF loads across temperature.

FAQ

Is the 74LV1T86GXH pin-compatible with other 5-pin logic gates in X2SON5?

Yes - the 74LV1T86GXH uses the standardized SOT1226-3 (X2SON5) pinout: Pin 1 = B, Pin 2 = A, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC. This matches Nexperia's LV1T-series single-gate portfolio (e.g., 74LV1T04, 74LV1T08), enabling drop-in substitution in layout-constrained designs without footprint changes.

Can the 74LV1T86GXH translate between 1.2 V and 5.0 V in a single direction?

Yes - when VCC = 5.0 V, the device accepts 1.2 V inputs (VIH min = 2.10 V at VCC = 5.5 V, but functional down to 1.2 V per up-translation spec) and outputs full 5.0 V CMOS levels. The datasheet explicitly lists "1.2 V to 1.8 V at VCC = 1.8 V" and "3.3 V to 5.0 V at VCC = 5.0 V", confirming scalable up-translation across the full range.

What is the maximum capacitive load the 74LV1T86GXH can drive reliably at 125 °C?

At +125 °C and VCC = 3.3 V, the device maintains tpd ≤ 7.6 ns into 30 pF (Table 8), and VOL ≤ 0.35 V at IOL = 5.5 mA (Table 7). These specs confirm reliable 30 pF drive capability across the full temperature range, matching typical PCB trace + receiver input capacitance in industrial backplanes.

Does the X2SON5 package require solder paste stencil adjustments compared to TSSOP5?

Yes - X2SON5 (SOT1226-3) has no leads and relies on bottom-terminal soldering. Recommended stencil aperture is 0.25 mm × 0.25 mm with 0.1 mm thickness for each of the five terminals, plus a 0.4 mm × 0.4 mm opening for the thermal pad. Reflow profile must include soak (150–180 °C for 90 s) and peak (245 °C for 10 s) per IPC-7095B guidelines.
