74LVC1G34GF000

Overview

The 74LVC1G34GF000 is a single non-inverting buffer manufactured by NXP USA Inc., belonging to the LVC/LCX/Z series. It utilizes high-performance, low-voltage Si-gate CMOS technology and operates within a supply voltage range of 1.65 V to 5.5 V. The device features Schmitt-trigger inputs for noise tolerance and I_OFF circuitry to prevent backflow current during partial power-down. It supports mixed 3.3 V and 5 V environments and complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36.

Feature Summary

• Schmitt-trigger action at all inputs provides high tolerance to slower input rise and fall times.
• I_OFF circuitry disables the output to prevent damaging backflow current when powered down.
• Inputs can be driven from either 3.3 V or 5 V devices, enabling use in mixed voltage environments.

Applications

• Mixed 3.3 V and 5 V system interfacing
• Partial power-down applications requiring backflow prevention
• Signal buffering in low-voltage CMOS logic circuits

Procurement Notes

Verify the specific package type associated with the GF000 suffix against official NXP documentation, as standard datasheets list XSON, TSOP, or TSSOP options. Confirm RoHS compliance status directly with the manufacturer, as some legacy records indicate non-compliance for similar variants. Ensure the ordering part number matches the required thermal and mechanical specifications for your PCB layout.

Selection Notes

Select this component when a single-channel non-inverting buffer is required for low-voltage digital signals. It is suitable for designs needing Schmitt-trigger input hysteresis to mitigate noise on slow-rising signals. The wide supply range allows flexibility in systems operating between 1.65 V and 5.5 V. Consider the I_OFF feature if the design requires safe operation during standby or partial power states.

Part Context

This part belongs to the 74LVC1G34 family of single buffers from NXP (formerly Nexperia/Philips). The family offers various package options including XSON, TSOP, and TSSOP. The LVC series is designed for low-power applications while maintaining compatibility with TTL levels. The GF000 designation specifies a particular package variant within this broader logical family.

Replacement Considerations

The 74LVC1G34GV,125 is a documented substitute part number available from Nexperia. Verify pinout and package dimensions before substitution, as the GF000 suffix implies a specific physical form factor that may differ from the GV or GM variants.
