Nexperia USA Inc. 74LV1T34GVH

Overview

74LV1T34GV from Nexperia is a single-supply CMOS level-translating buffer supporting bidirectional voltage translation across 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic domains. It features 5 V tolerant inputs, operates from 1.6 V to 5.5 V supply, delivers propagation delays as low as 3.1 ns (VCC = 5.0 V, CL = 15 pF), and is qualified for -40 °C to +125 °C ambient operation. It enables interface bridging between mixed-voltage subsystems in portable power management circuits.

For engineers reviewing the 74LV1T34GV datasheet, 74LV1T34GV pinout, 74LV1T34GV application, or 74LV1T34GV equivalent, key selection criteria include input threshold compatibility with 1.8 V drivers at 3.3 V VCC, output drive strength at 2.5 V/3.3 V, thermal performance in SC-74A packaging, and ESD robustness per JS-001 Class 2 (>2000 V HBM).

Technical Context

The device implements a single-channel unidirectional buffer with input thresholds dynamically scaled 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 only one supply rail. Its 5 V tolerant inputs allow direct connection to legacy 5 V logic without external resistors or clamping diodes.

Static input thresholds are specified across VCC range: VIH = 0.65 V (min) at VCC = 3.0 V, VIL = 0.80 V (max) at VCC = 5.5 V; output drive capability supports ±5.5 mA at 3.3 V and ±8 mA at 5.0 V while maintaining VOL ≤ 0.35 V and VOH ≥ 4.5 V under load.

FAQ

What is the maximum input voltage the 74LV1T34GV can tolerate when VCC = 2.5 V?

The 74LV1T34GV supports input voltages up to 5.5 V regardless of VCC setting, per Table 5 (Limiting Values). At VCC = 2.5 V, this enables safe down-translation from 3.3 V or 5.0 V sources without external protection - verified by 5 V tolerant input specification and JESD78 Class II latch-up immunity.

Can the 74LV1T34GV be used for bidirectional level translation?

No - the 74LV1T34GV is strictly unidirectional (input A → output Y). Its functional diagram and truth table confirm single-path operation. For bidirectional use, consider the SN74LVC1T45, which includes direction-control logic and auto-sensing capability not present in this device.

Does the n.c. pin (Pin 1) require any PCB layout treatment?

Pin 1 is internally not connected and must remain unbonded and floating. No PCB trace, via, or solder mask opening is needed. Leaving it unconnected avoids parasitic capacitance or unintended coupling that could degrade high-speed edge integrity in adjacent signal paths.

How does the 74LV1T34GV handle input transition rates, and what is the impact on timing?

The device specifies a maximum input transition rate of 20 ns/V (Δt/ΔV) across its full VCC range. Exceeding this may cause metastability or increased propagation delay variation. At VCC = 3.3 V, input edges slower than 66 ns (3.3 V × 20 ns/V) are guaranteed to meet datasheet timing specs - critical for reliable operation with slow-rising microcontroller reset signals.
