Nexperia USA Inc. 74LV1T34GV-Q100H

Overview

74LV1T34GV-Q100 from Nexperia is a single-supply, automotive-qualified level-translating buffer supporting bidirectional voltage translation across 1.8 V, 2.5 V, 3.3 V, and 5.0 V CMOS logic domains. It performs up-translation (e.g., 1.8 V input → 3.3 V output at VCC = 3.3 V) and down-translation (e.g., 5.0 V input → 3.3 V output at VCC = 3.3 V), features 5 V tolerant inputs, operates from −40 °C to +125 °C, and is used in automotive infotainment power sequencing interfaces.

For engineers reviewing the 74LV1T34GV-Q100 datasheet, 74LV1T34GV-Q100 pinout, 74LV1T34GV-Q100 application, or 74LV1T34GV-Q100 equivalent, key selection criteria include supply-voltage-dependent VIH/VIL thresholds, propagation delay vs. load capacitance (e.g., 3.7 ns typ. at 3.3 V/15 pF), 5 V input tolerance, AEC-Q100 Grade 1 qualification, and SC-74A (SOT753) package compatibility with space-constrained PCB layouts.

Technical Context

This device implements a single-channel unidirectional buffer with input threshold levels dynamically scaled to VCC - enabling reliable recognition of low-voltage logic (e.g., 1.8 V inputs at VCC = 3.3 V) while maintaining 5 V tolerant inputs. Its internal structure avoids external biasing or dual supplies, simplifying integration into mixed-voltage automotive subsystems.

Logic behavior follows standard non-inverting truth table (A → Y), with static drive strength specified at ±2 mA (VCC = 1.8 V) to ±8 mA (VCC = 5.0 V), and dynamic performance characterized across temperature and capacitive loads up to 30 pF. ESD robustness meets HBM >2000 V and CDM >1000 V per JEDEC JS-001/JS-002.

FAQ

Is pin 1 of the 74LV1T34GV-Q100 marked on the package?

Yes, pin 1 is identified by a dot or notch located on the lower-left corner of the SC-74A (SOT753) package, directly below the "SQ" marking code. This physical indicator aligns with the functional pin diagram showing pin 1 as n.c., ensuring correct orientation during automated placement and manual inspection.

Can the 74LV1T34GV-Q100 translate 5 V inputs down to 1.8 V outputs?

No - the device supports down-translation only to output voltages equal to VCC. To generate a 1.8 V output from a 5 V input, VCC must be set to 1.8 V. At that condition, the 5 V tolerant input is valid, and the output swings between 0 V and 1.8 V, satisfying 1.8 V CMOS logic thresholds.

What is the maximum capacitive load the 74LV1T34GV-Q100 can drive reliably?

The device is characterized up to 30 pF load capacitance across all VCC options, with propagation delay increasing predictably (e.g., 4.3 ns typ. at 3.3 V/30 pF). Driving >30 pF may exceed timing margins in high-speed applications and is not validated - external buffering is recommended beyond this limit.

Does the 74LV1T34GV-Q100 require external pull-up or pull-down resistors on its inputs?

No - the input has defined VIH and VIL thresholds across VCC range (e.g., VIH = 1.35 V min at VCC = 3.3 V), and input leakage is ≤±1 μA. Resistors are unnecessary unless specific noise immunity or default-state biasing is required by system architecture - not inherent to device operation.
