SN74LVC1404DCUR

Specialty Logic Overview

The SN74LVC1404DCUR is a single oscillator driver from Texas Instruments designed for crystal oscillators or ceramic resonators. It operates within a supply voltage range of 1.65V to 3.6V and utilizes a 5-pin SC-70 surface-mount package. The device features low power consumption with a maximum static current of 10µA and supports output drive currents of up to 24mA. It functions reliably across an extended temperature range from -40°C to +85°C, ensuring stable performance in various electronic applications.

Specialty Logic Feature Summary

• Integrated oscillator driver architecture optimized for direct connection to crystal oscillators or ceramic resonators
• Low-power CMOS technology providing minimal static current consumption during operation
• Robust output drive capability supporting high-speed signal transitions for clock generation

Specialty Logic Applications

• Crystal oscillator circuits requiring dedicated driving components
• Ceramic resonator interfaces in embedded systems
• Clock generation modules for microcontrollers and digital logic

Specialty Logic Procurement Notes

Verify the specific suffix 'DCUR' corresponds to the SC-70 package and tape-and-reel quantity when sourcing. Confirm that the operating voltage requirements align with your system's 1.65V to 3.6V rail specifications. Ensure thermal management meets the -40°C to +85°C ambient temperature constraints defined in the datasheet.

Specialty Logic Selection Notes

Select this component when a dedicated driver is required for crystal or ceramic resonator applications rather than general-purpose inverters. Compare against the SN74LVC1GX04 series if alternative packaging or slightly different electrical characteristics are needed. Ensure the SC-70 footprint fits your PCB layout constraints compared to larger packages like SOT-353.

Specialty Logic Part Context

This part belongs to the SN74LVC1404 family of oscillator drivers manufactured by Texas Instruments. It is distinct from standard logic gates, serving specifically as a driver for frequency control elements. The DCUR designation indicates the specific SC-70 surface-mount package variant within this product line.

Specialty Logic Replacement Considerations

The SN74LVC1GX04 is a documented substitute within the same manufacturer's portfolio offering similar oscillator driver functionality.
