74LVCH16646APAG

Overview

The IDT 74LVCH16646APAG is a 16-bit bus transceiver and register featuring 3-state outputs, manufactured by Integrated Device Technology Inc. It operates within a voltage range of 2.7 V to 3.6 V and utilizes LVTTL input and output levels. The device provides bidirectional data transmission with independent control capabilities, supporting both registered and real-time data modes. Packaged in a 56-pin TSSOP format, it is designed for surface-mount applications and supports non-inverting logic functions.

Feature Summary

• Provides 16-bit bidirectional data transmission with integrated registration capability
• Features 3-state outputs for effective bus line management
• Supports independent direction control for multiplexed data transmission

Applications

• High-density memory interface systems
• Buffering and bus-oriented circuits
• Clock drivers and buffered splits

Procurement Notes

Verify the specific manufacturer source, as IDT was acquired by Renesas Electronics. Confirm that the component matches the original IDT specifications rather than generic equivalents. Ensure the package type corresponds exactly to the 56-TFSOP or TSSOP variant required for your PCB footprint. Check RoHS compliance status if environmental regulations apply to your assembly process.

Selection Notes

Select this component when a 16-bit wide data path with latching functionality is required. It is suitable for designs needing low voltage operation between 2.7 V and 3.6 V. Consider its 3-state output capability for shared bus architectures. Verify that the TSSOP-56 package dimensions fit your board space constraints before finalizing the design.

Part Context

This part belongs to the LVCH series of high-speed CMOS logic devices. It serves as a critical interface component in digital systems requiring reliable data transfer between microprocessors and peripheral devices. The integration of registers allows for synchronized data handling, distinguishing it from simple transceivers.

Replacement Considerations

Cross-reference with SN74ABT16646DLR for similar 16-bit transceiver functions. Compare pinouts and electrical characteristics carefully to ensure compatibility.
