Nexperia USA Inc. 74LV1T125GVH

Overview

74LV1T125GVH from Nexperia is a single-supply, 5-pin CMOS level-translating buffer/line driver with 3-state output, supporting bidirectional voltage translation (e.g., 1.8 V ↔ 3.3 V, 3.3 V ↔ 5.0 V) across V_CC = 1.6 V to 5.5 V, operating from –40 °C to +125 °C, and featuring 5 V tolerant inputs for mixed-voltage interconnect in portable and industrial controllers.

For engineers reviewing the 74LV1T125GVH datasheet, 74LV1T125GVH pinout, 74LV1T125GVH application, or 74LV1T125GVH equivalent, this device delivers verified up/down translation capability, sub-5 ns propagation delay at 3.3 V/15 pF, 5 V input tolerance, ±25 mA output drive, and IEC-compliant ESD robustness - critical for low-power interface bridging between legacy and modern logic domains.

Technical Context

The 74LV1T125GVH implements a single-channel non-inverting buffer with active-low 3-state control (OE), where output state is directly referenced to V_CC, enabling precise CMOS-level output generation (1.8 V/2.5 V/3.3 V/5.0 V) independent of input voltage. Its input threshold adapts dynamically: VIH/VIL shift with V_CC to support reliable 1.2 V → 1.8 V up-translation and 5 V → 3.3 V down-translation.

Functional behavior follows a strict truth table: OE = L enables pass-through (A → Y), OE = H forces high-impedance (Z), with no internal latching or clocking. All static and dynamic parameters - including t_pd = 3.8 ns (typ.), t_en/t_dis ≤ 13 ns, and I_I ≤ ±0.1 μA - are fully characterized across –40 °C to +125 °C and V_CC = 1.6 V–5.5 V.

FAQ

Is 74LV1T125GVH pin-compatible with other SOT753 logic buffers?

Yes - the 74LV1T125GVH shares the identical SC-74A (SOT753) 5-pin footprint and pinout (OE-A-GND-Y-V_CC) with industry-standard single-gate buffers like 74LVC1G125 and 74AUP1G125, enabling drop-in replacement in existing layouts without PCB revision.

Can 74LV1T125GVH translate 5 V inputs when powered from 1.8 V?

Yes - its inputs are explicitly rated to –0.5 V to +7.0 V regardless of V_CC, allowing safe 5 V signal reception at V_CC = 1.8 V. Output will swing 0 V to 1.8 V, enabling verified 5 V → 1.8 V down-translation per datasheet Table 4 and Section 2.

What is the maximum capacitive load the 74LV1T125GVH can drive reliably?

The device is characterized up to 30 pF (Table 8), with t_pd = 4.4 ns (max) at V_CC = 3.3 V. For loads >30 pF, propagation delay increases linearly; design margin requires limiting total trace + load capacitance to ≤25 pF for sub-5 ns timing-critical paths.

Does 74LV1T125GVH require external pull-up or pull-down resistors on OE or A?

No - OE and A have CMOS-compatible input structure with ±0.1 μA leakage (Table 7). External resistors are unnecessary unless system-level noise immunity or default-state assurance is required; OE may be tied directly to GND (always enabled) or V_CC (always disabled) as needed.
