SN74ALVCH16601DL

Overview

The SN74ALVCH16601DL is an 18-bit universal bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and utilizes CMOS technology from the ALVCH logic series. The device features 3-state outputs and is housed in a 56-pin SSOP package. It supports bidirectional data transfer with independent control for each direction. The component functions as a registered bus transceiver, ensuring data integrity through clocked operation. It is designed for surface-mount installation and complies with RoHS standards.

Feature Summary

• Provides 18-bit bidirectional data transmission capability
• Features registered architecture for synchronized data handling
• Supports 3-state outputs for effective bus isolation
• Operates across a wide voltage range from 1.65 V to 3.6 V

Applications

• High-density data bus interfaces
• Memory-to-memory data transfers
• System-level register buffering
• General-purpose universal bus exchange

Procurement Notes

Verify the specific suffix 'DL' corresponds to the 56-SSOP package variant when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the supplier provides valid traceability for the Texas Instruments manufacturer part number. Check for any specific handling requirements related to the CMOS technology family during storage and assembly.

Selection Notes

Select this component for applications requiring 18-bit width with registered output capabilities. The ALVCH series offers performance suitable for low-voltage systems operating between 1.65 V and 3.6 V. Consider the 56-SSOP package constraints for PCB layout. Verify that the bidirectional nature and 3-state outputs align with the system's bus topology requirements.

Part Context

This device belongs to the Texas Instruments SN74ALVCH16601 family of universal bus transceivers. It shares functional similarities with other 18-bit bus devices but is distinguished by its registered output structure. The ALVCH series is designed for low-voltage CMOS applications, offering compatibility with various digital logic families while maintaining high-speed performance characteristics typical of advanced bus interface components.

Replacement Considerations

The SN74ALVC16601DL serves as a non-registered alternative within the same package footprint. The SN74ALVCHR16601GR is a registered variant available in a TSSOP-56 package. Cross-referencing with NXP's 74ALVT16601DL may require voltage level verification due to different supply specifications.
