74ACTQ16543SSC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ16543SSC is a 16-bit registered transceiver featuring 3-STATE outputs, housed in a 56-Lead Shrink Small Outline Package (SSOP). It utilizes FACT Quiet Series technology to ensure quiet output switching and improved dynamic threshold performance. The device contains two sets of D-type registers for temporary data storage, allowing independent control of each byte or full 16-bit operation. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Utilizes Fairchild FACT Quiet Series technology for guaranteed simultaneous switching noise levels and dynamic threshold performance.
• Features independent registers for A and B buses with separate controls for data flow in each direction.
• Provides back-to-back registers for storage and multiplexed real-time and stored data transfers.
• Includes separate control logic for each byte, allowing individual or combined 16-bit operation.

• Multiplex and Fanout applications
• SONET/SDH Clock/Data Multiplexing and Distribution
• Fibre Channel and Gigabit Ethernet Clock/Data Multiplexing
• Servers and Routers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the specific suffix; SSC denotes the SSOP variant. Confirm the presence of the 'X' suffix if tape and reel packaging is required. Ensure the design complies with the recommended operating conditions, specifically the 4.5V to 5.5V supply voltage range. Check for any specific marking specifications or compliance documents if RoHS status is critical for the application.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit registered transceiver with independent byte control is required. It is suitable for designs needing guaranteed pin-to-pin output skew and low simultaneous switching noise. Consider the 56-lead SSOP package constraints regarding board space and thermal management. Verify that the 24 mA source/sink current capability meets the load requirements of the connected circuitry.
