74LCXZ16245MTDX

Overview

The Fairchild Semiconductor 74LCXZ16245MTDX is a dual 16-bit bus transceiver from the 74LCX logic family. It features non-inverting polarity and operates within a supply voltage range of 2 V to 3.6 V. The device utilizes TSSOP-48 surface-mount packaging with 48 pins. Key electrical parameters include a maximum propagation delay of 5.2 ns at 50 pF load capacitance, and output drive capabilities of ±24 mA. Input levels support LVTTL and TTL standards, while outputs provide LVCMOS levels. The component functions across an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Dual 16-bit bidirectional data path architecture
• Bus hold functionality for signal stability
• LVTTL/TTL input compatibility with LVCMOS outputs
• Low power CMOS technology implementation

Applications

• High-density memory bus interfacing
• Clock distribution networks
• Data acquisition systems
• Mobile communication equipment

Procurement Notes

Verify the specific suffix 'Z' against official Fairchild or onsemi datasheets, as standard listings typically use 'MTDX'. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to procurement. Ensure the supplier provides traceable documentation matching the exact part number to avoid receiving generic LCX equivalents.

Selection Notes

Select this component when designing systems requiring 32-channel bidirectional data transfer in a compact footprint. The 74LCX series offers superior speed compared to older HC/HCT families while maintaining low power consumption. Verify that the system's I/O voltage requirements align with the specified 2V to 3.6V operating range and that the 5.2ns delay meets timing constraints.

Part Context

This device belongs to the 74LCX family of advanced low-voltage CMOS logic devices. Manufactured originally by Fairchild Semiconductor, which was acquired by onsemi, these components are widely used in portable electronics and high-speed digital interfaces. The MTDX suffix indicates a tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

The 74LCXH16245MTDX is a documented similar alternative offering comparable performance characteristics. Other compatible options may include variants from the 74LVCH series depending on specific voltage and speed requirements.
