74LV1T34GW-Q100H

Overview

The Nexperia 74LV1T34GW-Q100H is a single supply translating buffer qualified to AEC-Q100 Grade 1. It operates within a supply voltage range of 1.6 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device provides up translation (e.g., 1.8 V to 3.3 V) and down translation (e.g., 3.3 V to 1.8 V). Propagation delay ranges from 3.1 ns to 11.4 ns depending on load capacitance and voltage. Input leakage current is ±1 μA, and supply current is 10 μA.

Feature Summary

• Supports bidirectional level translation between 1.8 V, 2.5 V, 3.3 V, and 5.0 V CMOS levels
• Features 5 V tolerant inputs for safe interfacing with higher voltage logic
• Includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)
• Latch-up performance exceeds 250 mA per JESD 78 Class II

Applications

• Portable applications
• PC and notebooks
• Industrial controller systems
• Telecom equipment

Procurement Notes

Verify the specific package variant during procurement, as the GW suffix denotes the TSSOP5 (SOT353-1) package. Confirm that the component meets the required automotive qualification standards if used in Grade 1 environments. Ensure input transition rates remain below 20 ns/V to maintain specified dynamic characteristics. Check for any recent Product Change Notifications regarding marking or packaging updates.

Selection Notes

Select this component when a single-channel non-inverting buffer is required for translating signals between different voltage domains. It is suitable for connecting controllers or processors operating at varying supply voltages. Consider the propagation delay specifications relative to the system clock speed and load capacitance requirements. Verify that the 5 V tolerant input capability matches the source signal levels.

Part Context

This part belongs to the Nexperia 74LV1T34-Q100 family of single supply translating buffers. It is designed for automotive and industrial applications requiring robust voltage level shifting. The device complements other logic families by providing reliable interface solutions between low-voltage and standard voltage logic circuits.

Replacement Considerations

The 74LV1T34GV-Q100H serves as a direct functional replacement, differing only in package type (SC-74A/SOT753 instead of TSSOP5).
