Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering code suffix against manufacturer documentation to confirm package type and lead-free status. Confirm availability as this component may be subject to lifecycle changes. Ensure the selected variant matches the required JEDEC package standard for your PCB layout.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when low simultaneous switching noise and high dynamic threshold performance are critical. It offers faster propagation delays compared to standard ACT245 devices. Ensure the system design meets the recommended operating conditions for VCC and input edge rates to maintain reliability.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACTQ245 family, which integrates advanced silicon-gate CMOS technology. It is functionally compatible with standard 74ACT logic families but includes enhanced noise reduction features. The MSA20 package designation indicates a 20-Lead Shrink Small Outline Package (SSOP).

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check datasheets for 74ACT245 variants from other manufacturers to verify pinout compatibility and electrical parameter alignment. Ensure substitute components support the same SSOP package dimensions and thermal characteristics.
