74LVC3G34DP,125

Overview

The Nexperia 74LVC3G34DP,125 is a triple buffer in an 8-lead TSSOP package. It operates with a supply voltage range of 1.65 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device provides ±24 mA output drive at 3.0 V and includes Schmitt-trigger action for noise immunity. Static characteristics include a maximum input leakage current of ±1 μA and a typical supply current of 0.1 μA. Dynamic performance specifies propagation delays ranging from 1.9 ns to 10.8 ns depending on voltage. It supports partial power-down via I_OFF circuitry and complies with JEDEC standards.

Feature Summary

• Triple non-inverting buffer configuration
• Overvoltage tolerant inputs compatible with 5 V logic
• Schmitt-trigger inputs for improved noise immunity
• I_OFF circuitry prevents backflow during power-down

Applications

• Translating signals between mixed 3.3 V and 5 V environments
• Buffering digital signals with slow rise and fall times
• Partial power-down applications requiring backflow prevention

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74LVC3G34 series includes multiple variants such as DC, GT, GN, and GS. Confirm that the temperature range meets application requirements, noting that the DP variant is specified from -40 °C to +125 °C. Ensure design compliance with absolute maximum ratings to prevent permanent damage.

Selection Notes

Select this component when a compact triple buffer is needed for low-voltage CMOS applications. The wide supply range and TTL compatibility make it suitable for interfacing with various logic families. Consider the TSSOP8 package dimensions if board space is constrained. Verify that the output drive capability meets the load requirements for the specific application voltage.

Part Context

This part belongs to the Nexperia 74LVC family of advanced low-voltage CMOS logic devices. The 74LVC3G34 series specifically offers triple buffer functionality in mini packages. These devices are designed for high-speed operation with low power consumption, supporting modern portable and battery-powered electronics.

Replacement Considerations

Direct replacements within the same family include other 74LVC3G34 variants with different packages, such as 74LVC3G34DC (VSSOP8), 74LVC3G34GT (XSON8), 74LVC3G34GN (XSON8), and 74LVC3G34GS (XSON8). Ensure pinout compatibility and thermal derating limits match the new package.
