74LVC1G240GSH

Overview

The Nexperia 74LVC1G240GSH is a single inverting buffer and line driver with three-state outputs, housed in an XSON6 package (SOT1202). It operates within a supply voltage range of 1.65 V to 5.5 V and supports input voltages up to 5.5 V. The device features Schmitt-trigger inputs for noise immunity and includes IOFF circuitry to prevent backflow current during partial power-down states. It provides ±24 mA output drive capability at 3.0 V and complies with JEDEC standards for various voltage levels.

Feature Summary

• Provides high-impedance OFF-state via the OE pin when driven HIGH
• Features Schmitt-trigger action on all inputs to tolerate slow signal transitions
• Includes IOFF circuitry to disable outputs and prevent damaging backflow currents during power-down
• Supports direct interfacing with TTL logic levels

Applications

• Translating signals between mixed 3.3 V and 5 V environments
• Driving transmission lines as a line driver
• Partial power-down applications requiring isolation of powered-off circuits

Procurement Notes

Verify that the specific suffix GSH corresponds to the SOT1202 XSON6 package variant. Confirm the operating temperature range matches the design requirements, as the datasheet specifies availability from -40 °C to +125 °C. Ensure ESD protection ratings meet system safety standards before finalizing procurement.

Selection Notes

Select this component when a compact, single-channel inverting buffer with three-state control is required. The wide supply voltage range allows flexibility in low-power designs. Consider the XSON6 package dimensions if board space is constrained. Verify that the propagation delay characteristics align with the target clock frequencies.

Part Context

This device belongs to the 74LVC family of CMOS logic ICs, designed for low-voltage operation. The 74LVC1G240 specifically serves as a 1-bit inverting buffer. Other variants in the series include non-inverting buffers and multi-gate configurations, but this part number denotes the specific inverting function with three-state capabilities.

Replacement Considerations

Check for other 74LVC1G240 variants with different package options such as TSSOP5 or X2SON5 if mechanical fitment changes are acceptable. Ensure any substitute maintains the same SOT1202 footprint and pinout configuration.
