Nexperia USA Inc. 74LV1T04GXH

Overview

74LV1T04GXH from Nexperia is a single-supply, level-translating inverting buffer IC designed for voltage domain bridging between mixed-voltage logic systems. It supports bidirectional level translation (up and down), operates across 1.6 V to 5.5 V supply, features 5 V tolerant inputs, and delivers CMOS-compatible output levels at 1.8 V, 2.5 V, 3.3 V, or 5.0 V - enabling direct interface between 1.8 V microcontrollers and 3.3 V peripherals in portable embedded designs.

For engineers reviewing the 74LV1T04GXH datasheet, 74LV1T04GXH pinout, 74LV1T04GXH application, or 74LV1T04GXH equivalent, this device is selected for low-pin-count, space-constrained voltage translation where supply rail flexibility, input tolerance, and guaranteed propagation delay under load are critical selection criteria.

Technical Context

The 74LV1T04GXH implements a single-stage CMOS inverter with input threshold voltages dynamically scaled to VCC (e.g., VIH ≈ 0.7×VCC, VIL ≈ 0.3×VCC), enabling reliable switching across its full 1.6–5.5 V operating range. Its 5 V tolerant inputs allow safe connection to higher-voltage buses without external resistors or clamping diodes.

It performs true level translation: when VCC = 1.8 V, it accepts 3.3 V inputs and outputs 1.8 V logic; when VCC = 3.3 V, it accepts 1.8 V inputs and outputs 3.3 V logic. Propagation delay is load- and supply-dependent - e.g., 3.7 ns typical at VCC = 3.3 V, CL = 15 pF - and remains stable over -40 °C to +125 °C.

FAQ

Is the 74LV1T04GXH pin-compatible with other 74LV1T04 variants like GW or GV?

Yes - all 74LV1T04 variants (GW/TSSOP5, GV/SC-74A, GX/X2SON5) share identical pin 1 indexing and functional pinout: Pin 1 (n.c.), Pin 2 (A), Pin 3 (GND), Pin 4 (Y), Pin 5 (VCC). Mechanical dimensions and thermal characteristics differ, but electrical behavior and PCB footprint assignment are consistent across packages.

Can the 74LV1T04GXH translate 5 V inputs down to 1.8 V outputs?

No - while its inputs tolerate up to 7.0 V, the output swing is strictly referenced to VCC. To generate 1.8 V outputs, VCC must be set to 1.8 V. At VCC = 1.8 V, it accepts 3.3 V or 5 V inputs and outputs 1.8 V logic; however, 5 V → 1.8 V translation is not characterized or guaranteed in the datasheet.

What is the maximum capacitive load the 74LV1T04GXH can drive while maintaining timing specs?

The datasheet specifies propagation delay up to CL = 30 pF across all VCC conditions (e.g., 4.3 ns typ at VCC = 3.3 V, CL = 30 pF). Driving >30 pF increases delay nonlinearly and may violate setup/hold margins; for >50 pF loads, a buffer stage or lower-impedance driver is recommended.

Does the 74LV1T04GXH require external pull-up or pull-down resistors on unused pins?

Pin 1 is n.c. (no-connect) and must remain unconnected - no pull-up/pull-down required. Inputs (Pin 2) and outputs (Pin 4) should never float in operation; unused inputs must be tied to VCC or GND via ≤10 kΩ resistors to prevent oscillation and excess current draw.
