74LCX16543MTDX

Overview

The Fairchild Semiconductor 74LCX16543MTDX is a low-voltage CMOS device containing sixteen non-inverting transceivers with two sets of D-type registers for temporary data storage. It supports bidirectional data flow and features three-state outputs. The component operates within a supply voltage range of 2V to 3.6V, utilizing a 56-pin TSSOP package.

Feature Summary

• Contains sixteen non-inverting transceivers with integrated D-type registers for temporary data storage
• Supports bidirectional data flow between two distinct bus interfaces
• Features three-state outputs to facilitate efficient bus line driving

Applications

• Bidirectional bus drivers in low-voltage systems
• Temporary data storage applications using integrated registers
• Memory interface circuits requiring level translation

Procurement Notes

Verify the specific suffix 'D' indicates the tape-and-reel packaging configuration when sourcing. Confirm the manufacturer origin, as this part may be listed under ON Semiconductor following corporate restructuring. Ensure the datasheet matches the 56-TSSOP physical dimensions and electrical characteristics for your design requirements.

Selection Notes

Select this component for designs requiring bidirectional data transfer with built-in latching capabilities at low voltages. The integrated D-type registers simplify timing control by providing temporary storage during direction changes. Verify that the 2V to 3.6V operating range aligns with the system power rails and that the 56-pin form factor fits the PCB layout constraints.

Part Context

This device belongs to the LCX family of low-voltage CMOS logic components. It serves as a bridge between different voltage domains while managing data directionality. The inclusion of registers distinguishes it from standard transceivers by allowing data retention during mode switches, enhancing reliability in complex digital interfaces.

Replacement Considerations

The 74LCX16543MEA is a documented alternative variant. Verify pin compatibility and electrical specifications before substitution.
