SN74ALVCH162260DL

Overview

The SN74ALVCH162260DL is a registered bus exchanger manufactured by Texas Instruments. It operates within a supply voltage range of 1.65V to 3.6V and supports bidirectional data transfer between two buses with independent control for each direction. The device features D-type flip-flops that register data on the positive edge of the clock signal, providing high noise immunity and low power consumption typical of the ALVCH series. It is housed in a 56-pin SSOP package and is designed for surface-mount applications.

Feature Summary

• Registered bus exchange functionality with independent output enable for each direction
• Positive-edge triggered D-type flip-flops for data registration
• Bidirectional data transfer capability between two buses

Applications

• High-density data routing systems
• Bus isolation and buffering in embedded controllers
• Data acquisition systems requiring registered bus interfaces

Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to confirm pinout compatibility and electrical specifications. Ensure the procurement source provides valid traceability and authenticity guarantees, as counterfeit components may exhibit incorrect logic states or failure to meet specified voltage ranges.

Selection Notes

Select this component when registered bus isolation is required rather than transparent latching. Confirm that the system design utilizes a positive-edge triggered clock signal compatible with the ALVCH series timing requirements. Verify that the 56-pin SSOP package dimensions fit the target PCB layout constraints.

Part Context

This device belongs to the Texas Instruments 74ALVCH162260 family of registered bus exchangers. It is distinct from transparent latch variants like the 74ALVCH16260, offering data storage capabilities at the bus interface. The DL suffix indicates the 56-lead thin shrink small-outline package (SSOP) configuration.
