74LVC1G17GV,125

Overview

The Nexperia 74LVC1G17GV,125 is a single Schmitt trigger buffer in the LVC logic family. It operates within a supply voltage range of 1.65 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device utilizes IOFF circuitry for partial power-down mode operation, preventing backflow current. It provides an output drive of ±24 mA at VCC = 3.0 V and complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). The component is specified for ambient temperatures from -40 °C to +125 °C and is housed in the SC-74A (SOT753) package.

Feature Summary

• Schmitt-trigger action ensures tolerance to slow input rise and fall times
• IOFF circuitry enables partial power-down mode by disabling outputs
• Direct interface capability with TTL levels
• High noise immunity with CMOS low power dissipation

Applications

• Signal translation between mixed 3.3 V and 5 V environments
• Partial power-down applications requiring backflow current prevention
• Buffering signals with unlimited rise and fall times

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when a single-channel non-inverting buffer with hysteresis is required for noisy or slow-signal environments. The wide supply voltage range supports compatibility with various logic families. Ensure the design accommodates the specified temperature range and power dissipation derating curves for the SC-74A package.

Part Context

This part belongs to the Nexperia 74LVC1G17 series of single Schmitt trigger buffers. The 'GV' designation specifically identifies the SC-74A (SOT753) plastic surface-mounted package variant. Other package options in the series include TSSOP5, XSON6, and X2SON variants, all sharing identical electrical characteristics but differing in physical dimensions and thermal properties.

Replacement Considerations

Compatible substitutes include other 74LVC1G17 variants with different packages, such as 74LVC1G17GW (TSSOP5) or 74LVC1G17GM (XSON6), provided the PCB footprint allows. Cross-family replacements like 74HC1G17 may require voltage level adjustments.
