Overview
The IDT 74LVCH16543AXPA is a 16-bit registered bus transceiver designed for low-voltage CMOS operation. It supports mixed-mode signal environments, allowing compatibility between 3.3-V and 5-V systems. The device features independent output enables for each direction of data flow and includes latch-enable inputs to register data. It is housed in a 56-pin Thin Shrink Small-Outline (TSSOP) package.
Feature Summary
- Supports mixed-mode signal operations with 5-V tolerant inputs and outputs while operating at 3.3 V
- Provides independent control over data flow direction via separate latch-enable and output-enable inputs
- Includes bus hold circuitry on data inputs to eliminate the need for external pull-up or pull-down resistors
Applications
- High-density memory modules requiring bidirectional data transfer
- Clock drivers and buffered oscillators
- Bus-oriented communications systems
Procurement Notes
Verify the specific suffix 'XPA' against manufacturer documentation to confirm pinout and package dimensions. Ensure the component meets required moisture sensitivity levels for your assembly process. Confirm RoHS compliance status as it may vary by production batch. Cross-reference the ordering part number with official distributors to ensure authenticity and traceability.
Selection Notes
Select this component when designing systems that require 16-bit wide data paths with latching capabilities. It is suitable for applications needing interface bridging between 3.3-V logic and legacy 5-V devices. Consider the TSSOP-56 package constraints regarding PCB space and thermal management during layout.
Part Context
This device belongs to the LVCH series of high-speed CMOS logic components. It functions as a registered transceiver, combining buffering with data storage. The technology allows for low power consumption while maintaining high switching speeds, making it appropriate for portable and battery-operated electronics.
Replacement Considerations
SN74LVCH16543ADL from Texas Instruments is a documented alternative.
