74ACTQ16646SSCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ16646SSCX 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 utilizes FACT Quiet Series technology for improved dynamic threshold performance and guaranteed simultaneous switching noise levels. It features independent registers for A and B buses, allowing multiplexed real-time and stored data transfers. Outputs can source or sink 24 mA, with propagation delays ranging from 3.3 ns to 10.4 ns depending on the path and load conditions.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering code matches the SSOP package variant. Confirm the manufacturer origin, as this component was originally produced by Fairchild Semiconductor before acquisition by onsemi. Ensure compatibility with existing system voltage levels and thermal requirements before integration into new designs.

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 simultaneous switching noise performance and low pin-to-pin skew. Consider the 56-lead SSOP package constraints and ensure the application operates within the specified 4.5V to 5.5V supply voltage range.

Buffers, Drivers, Receivers, Transceivers Part Context
