ET74LVCSZ17

Overview

The ET74LVCSZ17 is a single non-inverting Schmitt trigger buffer manufactured by ETEK Microelectronics. It operates within a supply voltage range of 1.65V to 3.6V and features over-voltage tolerant inputs capable of accepting voltages up to 5.5V. The device provides balanced output sink and source currents of ±24mA. It is housed in an SC-70-5 surface-mount package, designed for low-power applications requiring signal conditioning and noise immunity.

Feature Summary

• Single-channel non-inverting buffer configuration with Schmitt trigger input characteristics
• Over-voltage tolerant inputs allowing compatibility with 5.5V logic levels despite lower supply operation
• Balanced output drive capability providing symmetric source and sink current performance

Applications

• Signal buffering in low-voltage digital systems
• Noise filtering and waveform shaping via Schmitt trigger action
• Level shifting interfaces between 1.8V/3.3V logic and 5V tolerant peripherals

Procurement Notes

Verify the specific suffix code on the component marking against the official ETEK datasheet to confirm pinout and electrical specifications. Ensure the SC-70-5 package variant matches the design footprint requirements. Confirm RoHS compliance status through the manufacturer's latest documentation before integration into production.

Selection Notes

Select this component when a single-channel buffer with hysteresis is required for noisy environments. The over-voltage tolerance simplifies interface design with mixed-voltage systems. Verify that the 24mA drive strength meets the load requirements of the destination circuitry without exceeding absolute maximum ratings.

Part Context

This part belongs to the 74LVCSZ series of low-voltage CMOS logic devices from ETEK Microelectronics. The series focuses on high-speed, low-power performance suitable for portable and battery-operated electronics. The LVCSZ designation indicates specific voltage ranges and packaging options distinct from standard 74LVC or HC families.

Replacement Considerations

Direct substitutes include other single non-inverting Schmitt buffers in SC-70-5 packages such as the SN74LVCSZ17 from Texas Instruments. Verify pin compatibility and electrical parameters like propagation delay and output current before substitution.
