Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DLR' corresponds to the TSSOP-56 surface-mount package configuration. Confirm that the ACT logic family specifications align with the target system's voltage requirements. Ensure compatibility with the required operating temperature range of -40°C to +85°C before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit registered transceiver with three-state outputs is required. The ACT series offers faster switching speeds compared to standard LS or HC families. Verify that the 4.5 V to 5.5 V supply voltage range matches the system design constraints and that the TSSOP-56 package fits the available PCB footprint.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74ACT logic family, designed for high-speed digital applications. It serves as a registered transceiver variant within the broader 74xx series ecosystem.
