MC74LCX16244DTR2

Overview

The MC74LCX16244DTR2 is a 16-bit CMOS buffer and line driver manufactured by onsemi. It operates within a supply voltage range of 2 V to 3.6 V. The device features non-inverting logic polarity and utilizes a TSSOP-48 surface-mount package. Electrical characteristics include a maximum propagation delay of 8 ns, with high-level output current capability of -24 mA and low-level output current of 24 mA. Static current consumption is specified at 5 µA, while operating power supply current reaches 10 µA. The component supports an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides 16-bit buffering for high-speed digital signal transmission
• Operates reliably across a wide 2 V to 3.6 V supply voltage range
• Features low static current consumption for energy-efficient designs

Applications

• High-density data bus buffering in portable electronics
• Clock distribution networks requiring low skew
• Memory interface circuits in consumer devices

Procurement Notes

Verify the exact suffix 'DTR2' against official datasheets to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status through manufacturer documentation. Ensure the TSSOP-48 footprint matches PCB design requirements. Check for end-of-life notices as some LCX series variants face obsolescence. Validate thermal performance for the intended operating environment.

Selection Notes

Select this component when 16-channel buffering is required within a compact TSSOP-48 footprint. It is suitable for systems operating between 2 V and 3.6 V where low power consumption is critical. Compare propagation delay specifications against system timing requirements. Consider pin compatibility if replacing older 74LCX variants in existing designs.

Part Context

This part belongs to the onsemi 74LCX family of low-voltage CMOS logic devices. The LCX series is designed for applications requiring fast switching speeds and low power dissipation. It serves as a bridge between different voltage domains in mixed-signal systems. The 16244 variant specifically provides non-inverting buffering functionality.

Replacement Considerations

Check for direct replacements like MC74LCX16244DTR2G which may have updated packaging or compliance markings. Verify pinout compatibility before substituting with other 16-bit buffers. Ensure voltage levels and drive strength meet original design specifications.
