74ACTQ16646MTDX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ16646MTDX is a 16-bit bidirectional registered bus transceiver with 3-state outputs. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. The device features independent registers for A and B buses, allowing multiplexed real-time and stored data transfers. It utilizes FACT Quiet Series technology for improved dynamic threshold performance and guaranteed simultaneous switching noise levels. The component is housed in a 56-lead Thin Shrink Small Outline Package (TSSOP).

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Utilizes FACT Quiet Series technology for quiet output switching and improved dynamic threshold performance.
• Provides independent registers for A and B buses to support multiplexed real-time and stored data transfers.
• Features separate control logic for each byte, enabling flexible configuration for full 16-bit operation.

Buffers, Drivers, Receivers, Transceivers Applications

• Multiplexed transmission of data directly from input bus or internal storage registers.
• Bidirectional registered bus transceivers requiring controlled data flow direction.
• Systems requiring guaranteed pin-to-pin output skew and simultaneous switching noise management.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering code suffix 'X' confirms tape and reel packaging availability. Confirm that the manufacturer designation aligns with current onsemi product lines, as historical documentation references Fairchild Semiconductor. Ensure compliance with RoHS standards and check for any relevant PCN announcements regarding manufacturing changes or material composition updates before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit bidirectional data transfer with integrated storage capabilities. It is suitable for applications needing independent byte control and low noise performance via FACT Quiet Series technology. Consider the TSSOP-56 package constraints and the 4.5V to 5.5V operating voltage range during circuit design. Evaluate the propagation delay specifications against system timing requirements for clock-to-bus and bus-to-bus transitions.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ACTQ series of high-speed CMOS logic components. It serves as a 16-bit version of the ACTQ646, offering expanded channel count while maintaining similar functional characteristics. The part integrates both transceiver and register functions into a single package, simplifying board layout for complex data bus architectures requiring synchronized data handling.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ACTQ16646MTD is the non-reel variant of this component. Verify pin compatibility if substituting with other 16-bit transceivers from the same family, such as the 74LVTH16646, noting differences in voltage levels and technology nodes.
