74LCXZ16245MTDX

Overview

The onsemi 74LCXZ16245MTDX is a low-voltage 16-bit bidirectional bus transceiver featuring three-state outputs. It operates within a supply voltage range of 2.0 V to 3.6 V and supports LVTTL or TTL input levels with LVCMOS output levels. The device provides a propagation delay of 5.2 ns, with low-level and high-level output currents of 24 mA and -24 mA respectively. Packaged in a 48-pin TSSOP, it functions as two non-inverting 8-bit elements.

Feature Summary

• Provides sixteen non-inverting bidirectional buffers with three-state outputs for bus-oriented applications.
• Features bus hold functionality to maintain data states during invalid input conditions.
• Supports low-voltage operation compatible with LVTTL and TTL input logic levels.

Applications

• Bus-oriented memory and disk drive controller systems
• High-density data acquisition and transmission systems
• Consumer electronics requiring low-voltage signal translation

Procurement Notes

Verify component authenticity through authorized distributors due to the prevalence of counterfeits in the logic IC market. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions before final integration into production designs.

Selection Notes

Select this component when designing systems requiring 16-bit bidirectional data transfer at low voltages. Ensure the system power supply remains within the 2.0 V to 3.6 V range. Verify that the required output current capability of 24 mA meets load requirements. Consider the TSSOP-48 package constraints for PCB layout and thermal management.

Part Context

This part belongs to the LCXZ series of low-voltage CMOS logic devices from onsemi. It is functionally similar to other 16-bit bus transceivers but optimized for lower voltage operation compared to standard 5V variants. The MTDX suffix indicates the specific tape-and-reel packaging configuration for automated assembly.

Replacement Considerations

Check for direct equivalents such as the 74LVT16245 for higher voltage compatibility or the 74LCXH16245 for slight parameter variations. Verify pinout compatibility and electrical specifications against alternative manufacturers' parts before substitution.
