74LCX16821MTD

Overview

The 74LCX16821MTD is a dual 10-bit bus driver from the LVC/LCX/Z series manufactured by Texas Instruments. It features true output polarity and utilizes a TSSOP-56 plastic package measuring 6.10 mm in width. The device supports a maximum operating frequency of 150 MHz at nominal supply voltage, with a load capacitance specification of 50 pF. It operates within a temperature range up to 85 °C and provides a maximum output current of 24 mA.

Feature Summary

• Dual 10-bit architecture providing two independent bus driver functions
• True output polarity for non-inverting signal transmission
• High-speed operation capability supporting frequencies up to 150 MHz
• Robust drive strength with 24 mA maximum output current capability

Applications

• Parallel data bus interfacing between logic levels
• Memory bus address and data line drivers
• High-speed digital signal routing in consumer electronics
• I/O expansion modules requiring level translation

Procurement Notes

Verify manufacturer designation as Texas Instruments despite initial Fairchild association in some databases. Confirm TSSOP-56 package dimensions and lead finish specifications match design requirements. Ensure RoHS compliance status aligns with project constraints, noting potential discrepancies in legacy documentation regarding environmental certification.

Selection Notes

Select this component for applications requiring dual-channel 10-bit bus driving with high speed. Compare against single-bit alternatives for pin count efficiency. Verify supply voltage compatibility with target system rails. Consider thermal performance within the 85 °C limit for enclosed designs.

Part Context

Part of the LCX family offering low-voltage CMOS performance. Designed for portable and battery-operated systems due to low power consumption. Provides interface solutions between different logic families while maintaining signal integrity at high speeds.

Replacement Considerations

Check for direct cross-reference part numbers from Texas Instruments or onsemi. Verify pinout compatibility before substitution. Ensure electrical parameters such as propagation delay and output current meet original design specifications.
