74ACT16543SSCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT16543SSCX is a 16-bit registered transceiver with 3-state outputs, housed in a 56-lead SSOP package. 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 TTL-compatible inputs and provides independent control for data flow direction between A and B buses. Each byte has separate latch enable and output enable inputs, allowing for multiplexed real-time and stored data transfers. Outputs can source or sink up to 24 mA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Independent registers for A and B buses allow for separate control of data flow in each direction.
• Back-to-back registers facilitate temporary storage of data flowing in either direction.
• Separate control logic for each byte enables independent input and output control.
• Outputs provide high drive capability by sourcing and sinking 24 mA.

Buffers, Drivers, Receivers, Transceivers Applications

• Data bus buffering in digital systems
• Temporary storage of data in bidirectional communication interfaces
• Multiplexed real-time and stored data transfer applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'X' indicates tape and reel packaging when sourcing this component. Confirm that the manufacturer documentation aligns with the requested package type and compliance standards. Ensure the procurement channel provides valid datasheets and quality certifications. Check for any specific handling requirements related to electrostatic discharge during storage and installation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional data transfer with latching capability is required. The independent byte control allows for flexible configuration of data paths. Consider the 3-state output feature for bus sharing applications. Verify that the TTL-compatible inputs match the driving logic levels of the system. Evaluate the package size constraints against the available board space.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ACT logic family, known for CMOS operation with TTL-compatible inputs. It is designed for high-speed digital applications requiring reliable data transmission. The registered transceiver architecture distinguishes it from standard bus transceivers by providing internal storage elements. This makes it suitable for applications needing data synchronization or temporary holding.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for equivalent parts from other manufacturers offering the same 16-bit registered transceiver functionality. Ensure pin compatibility and electrical specifications match the original design requirements. Verify that alternative packages are physically compatible with the existing footprint. Review any differences in switching characteristics or power consumption.
