ET74LVC1G17

Overview

The ET74LVC1G17 is a single non-inverting Schmitt trigger buffer manufactured by ETEK Microelectronics. It is designed for operation with supply voltages ranging from 1.65V to 5.5V. The device features over-voltage tolerant inputs and provides balanced output sink and source capabilities of ±32mA. It exhibits near-zero static supply current, making it suitable for low-power applications. The component is housed in an SC-70-5 package.

Feature Summary

• Single non-inverting Schmitt trigger buffer configuration
• Over-voltage tolerant input structure
• Balanced high-current push-pull output capability
• Ultra-low static power consumption design

Applications

• Mixed-signal level translation between 3.3V and 5V domains
• Signal conditioning for noisy digital environments
• Waveform shaping for slow-rise/fall time signals
• Buffering in portable battery-powered devices

Procurement Notes

Verify the manufacturer part number ET74LVC1G17 against official ETEK Microelectronics documentation to confirm pinout compatibility and electrical specifications. Ensure the SC-70-5 package variant matches your PCB footprint requirements. Cross-reference datasheet revisions to validate operating temperature ranges and I/O voltage tolerances before integration into production designs.

Selection Notes

Select this component when a single-channel buffer with hysteresis is required for signal integrity improvement. The wide supply voltage range supports both low-voltage and standard logic systems. The Schmitt trigger input is essential for cleaning up distorted signals. Verify that the ±32mA drive strength meets the load requirements of the downstream circuitry without exceeding absolute maximum ratings.

Part Context

This component belongs to the 74LVC family of CMOS logic devices, which are known for high-speed operation and low power consumption. The LVC series is widely used in consumer electronics and industrial control systems where interface flexibility between different voltage levels is necessary. The specific '1G' designation indicates a single-gate implementation in a minimal footprint package.

Replacement Considerations

Direct functional substitutes include the Nexperia 74LVC1G17 and Diodes Inc. 74LVC1G17W5-7. These alternatives share the same logical function and similar electrical characteristics. Verify package compatibility (SC-70-5 or equivalent) and ensure that the substitute's voltage tolerance and drive current meet the original design specifications.
