Nexperia USA Inc. 74LV1T34GW-Q100H

Overview

74LV1T34GW-Q100 from Nexperia is a single-supply, automotive-grade level-translating buffer supporting bidirectional voltage translation between 1.2 V and 5.0 V logic domains. It functions as a unidirectional signal translator in I/O interface paths, with 5 V tolerant inputs, 1.8–5.0 V CMOS-compatible outputs, and operation across -40 °C to +125 °C. Used in automotive infotainment and ADAS sensor interfaces requiring robust level-shifting under wide supply variation.

For engineers reviewing the 74LV1T34GW-Q100 datasheet, 74LV1T34GW-Q100 pinout, 74LV1T34GW-Q100 application, or 74LV1T34GW-Q100 equivalent, key selection criteria include input voltage tolerance (up to 7.0 V), propagation delay (as low as 3.1 ns at 5.0 V/15 pF), AEC-Q100 Grade 1 qualification, and compatibility with 1.65–5.5 V supply rails for mixed-voltage SoC interfacing.

Technical Context

This device implements a single-channel CMOS buffer with input threshold adaptive to VCC, enabling up-translation (e.g., 1.8 V → 3.3 V) and down-translation (e.g., 5.0 V → 3.3 V) using one supply rail. Its 5 V tolerant inputs operate independently of VCC, allowing safe interfacing with higher-voltage peripherals without external resistors or clamps.

The logic function is non-inverting (A → Y), with static drive strength specified at ±2 mA (VCC = 1.8 V) to ±8 mA (VCC = 4.5 V), and dynamic performance validated up to 50 MHz at 3.3 V with 30 pF load. Input leakage remains ≤±1 μA across full temperature range, ensuring low-power system standby integrity.

FAQ

Is 74LV1T34GW-Q100 pin-compatible with standard 74LVC1T34 variants?

Yes - it shares identical pinout (n.c./A/GND/Y/VCC) and footprint with SOT353-1 packaged 74LVC1T34 devices. However, its input threshold behavior and AEC-Q100 qualification differ: VIH/VIL are VCC-dependent per datasheet Table 7, and it supports wider VCC (1.6–5.5 V) versus typical 1.65–5.5 V. No layout change is needed for drop-in replacement in qualified designs.

Can 74LV1T34GW-Q100 perform bidirectional level translation?

No - it is a unidirectional buffer (A → Y only). The internal architecture lacks bus-hold or direction-control logic. For true bidirectional translation (e.g., I²C), a dedicated dual-supply translator like PCA9306 is required. This device is optimized for point-to-point control signal routing where direction is fixed.

What is the maximum capacitive load this buffer can drive reliably?

It is characterized up to 30 pF load capacitance with guaranteed timing (e.g., 6.3 ns max tpd at 1.8 V/30 pF). Driving >30 pF may increase propagation delay nonlinearly and degrade edge rate; for >50 pF loads, add series termination or consider higher-drive alternatives like 74LV1T125. Layout parasitics must be included in total CL calculation.

Does the n.c. pin require grounding or floating per design guidelines?

Pin 1 (n.c.) must remain unconnected - it is not bonded internally and has no electrical function. Grounding or routing to any potential violates the datasheet specification and may induce parasitic coupling or mechanical stress. Leave it floating with no solder mask opening or trace attachment per Nexperia's SOT353-1 assembly recommendations.
