74LV1T34GVH

Overview

The Nexperia 74LV1T34GVH is a single supply translating buffer housed in an SC-74A (SOT753) package. It supports a supply voltage range of 1.6 V to 5.5 V and features 5 V tolerant inputs. The device facilitates level translation between 1.8 V, 2.5 V, 3.3 V, and 5.0 V CMOS logic levels. Propagation delay ranges from 3.9 ns to 11.4 ns depending on the supply voltage and load capacitance. Operating temperature spans from -40 °C to +125 °C.

Feature Summary

• Supports up-translation from lower voltages such as 1.2 V to 1.8 V or 1.8 V to 3.3 V
• Enables down-translation from 3.3 V or 5.0 V sources to lower output levels
• Features 5 V tolerant input pins for interfacing with higher voltage logic
• Provides latch-up protection exceeding 250 mA per JESD 78 Class II

Applications

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

Procurement Notes

Verify the specific ordering suffix 'H' against the manufacturer's current documentation to confirm packaging details and reel specifications. Ensure the component matches the required SC-74A package variant. Confirm RoHS compliance status and check for any recent product change notifications that may affect pinout or marking codes before finalizing procurement orders.

Selection Notes

Select this component when a single-channel buffer is needed for mixed-voltage environments. It is suitable for connecting controllers or processors operating at different logic levels. Consider the propagation delay requirements relative to the system clock speed. Verify that the input signal levels fall within the specified thresholds for the chosen supply voltage configuration.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices manufactured by Nexperia. The 74LV1T34 family includes variants with different packages such as TSSOP5 and X2SON5. The GVH designation specifically identifies the SC-74A surface-mount package version. These buffers are designed for general-purpose level shifting in digital circuits.

Replacement Considerations

Direct substitutes include other 74LV1T34 variants like 74LV1T34GW or 74LV1T34GX if package compatibility allows. Cross-referencing with similar single-buffer translators from other manufacturers requires verifying pinout alignment and electrical parameter equivalence.
