74LVC1G125DBVTE4

Overview

The SN74LVC1G125DBVTE4 is a single bus buffer gate with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and accepts input voltages up to 5.5 V. The device features non-inverting logic, low power consumption with a maximum static current of 10 µA, and supports output drive currents of ±32 mA at 3.3 V. Propagation delay is specified as 4.5 ns at 3.3 V and 4 ns at 5 V. It is housed in an SOT-23-5 package and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Supports 5-V VCC operation while accepting inputs up to 5.5 V
• Enables partial-power-down mode via Ioff circuitry to prevent backflow
• Provides high-output drive capability for bus driving applications

Applications

• Portable consumer electronics requiring level shifting
• Memory and flash card interfaces
• High-speed data transmission lines

Procurement Notes

Verify the complete ordering part number against official Texas Instruments documentation to ensure correct suffixes for packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead-free manufacturing details directly from the manufacturer's datasheet or authorized distributor catalogs prior to procurement.

Selection Notes

Select this component when a single-channel, non-inverting buffer with three-state control is required for 1.65-V to 5.5-V systems. Consider its 5.5-V tolerant inputs for interfacing between different voltage domains. Evaluate the SOT-23-5 package constraints for space-limited designs and verify that the propagation delay meets system timing requirements.

Part Context

This device belongs to the SN74LVC1G125 series of single bus buffers. It utilizes Texas Instruments' NanoStar or NanoFree package technologies, which integrate the die directly into the package structure for minimal footprint. The LVC logic family provides compatibility with standard CMOS levels while offering improved speed and lower power consumption compared to older logic families.

FAQ

Does the device support partial-power-down mode?

Yes, the Ioff circuitry disables the outputs when the device is powered down, preventing damaging current backflow through the device.

What is the maximum input voltage tolerance?

The inputs accept voltages up to 5.5 V, allowing operation with 5-V VCC supplies even if the device itself operates at lower voltages.
