74LCXP16245MEAX

Overview

The 74LCXP16245MEAX is a 16-bit bus transceiver manufactured by onsemi, belonging to the LCXP logic family. It features bidirectional data flow with two independent circuits and includes a bus-hold function for level retention. The device operates within a supply voltage range of 2 V to 3.6 V and supports LVTTL or TTL input levels while providing LVCMOS output levels. Key electrical parameters include a propagation delay of 5.2 ns, low-level output current of 24 mA, and high-level output current of -24 mA. It is housed in a TSSOP-48 package and functions as a non-inverting transceiver with three-state outputs.

Feature Summary

• Integrates a bus-hold feature to maintain signal levels when inputs are disconnected
• Provides bidirectional data transmission across 16 channels
• Supports mixed voltage operation between LVTTL/TTL inputs and LVCMOS outputs

Applications

• High-density data buses in embedded systems
• Memory interface buffering
• I/O expansion modules

Procurement Notes

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Ensure design compatibility with specified voltage ranges and thermal limits before integration into final assemblies.

Selection Notes

Select this component for applications requiring 16-bit bidirectional communication with bus-hold capabilities. Verify that the system operates within the 2 V to 3.6 V supply range. Consider the TSSOP-48 footprint for PCB layout planning. Ensure input drivers support LVTTL or TTL levels for proper signal interfacing.

Part Context

This part belongs to the LCXP series of CMOS bus transceivers designed for low-voltage applications. It shares functional similarities with other 16-bit transceivers but distinguishes itself through integrated bus-hold functionality. The LCXP family targets high-speed digital interfaces where signal integrity and voltage translation are critical requirements.

Replacement Considerations

Consult official substitution guides for compatible parts. Verify pinout compatibility and electrical specifications before replacing. Ensure any substitute maintains the same bus-hold feature and voltage operating range.
