74LVC1G240DBVTG4

Overview

The SN74LVC1G240DBVTG4 is a single buffer and line driver from the Texas Instruments LVC logic family. It features one input and one output with inverting polarity and three-state output capability. The device operates within a supply voltage range of 1.65 V to 5.5 V, drawing a maximum static current of 10 uA. It provides high drive strength with output currents of -32 mA (high) and 32 mA (low). Propagation delay is specified at 4.2 ns at 5 V. It functions reliably across an extended temperature range from -40°C to +125°C and is housed in a compact SOT-23-5 surface-mount package.

Feature Summary

• Provides single-channel buffering and line driving with inverting logic functionality.
• Features three-state outputs for effective bus management and isolation.
• Supports wide supply voltage operation from 1.65 V to 5.5 V.
• Delivers strong drive capability with ±32 mA output current.

Applications

• Portable systems requiring low-voltage operation
• Battery-powered consumer electronics
• Cellular phones and handheld devices
• PDA and laptop computers

Procurement Notes

Verify the complete part number including the TG4 suffix to ensure RoHS compliance and green material status as specified by Texas Instruments. Confirm the SOT-23-5 package type matches your PCB footprint requirements. Check the datasheet for specific handling precautions related to electrostatic discharge sensitivity during assembly and storage processes.

Selection Notes

Select this component when a single inverting buffer with three-state control is required in space-constrained designs. The LVC series offers a balance of speed and power consumption suitable for 1.8V, 2.5V, and 3.3V systems. Ensure the application does not require non-inverting logic, in which case the 74LVC1G125 or similar variants should be considered instead.

Part Context

This device belongs to the SN74LVC1G240 family of single buffer/drivers. It shares functional similarities with other single-gate logic ICs but is distinct due to its specific inverting polarity and three-state output configuration. The LVC technology is designed for low-voltage applications, offering performance comparable to older CMOS families while consuming significantly less power.

Replacement Considerations

For pin-compatible replacements, consider other SN74LVC1G240 variants with different packaging options such as SN74LVC1G240DSFR or SN74LVC1G240YZPR. Verify that any substitute maintains the same inverting logic function and three-state output characteristics to ensure circuit compatibility.
