ADG3257BRQ

Signal Switches, Multiplexers, Decoders Overview

The ADG3257BRQ is a quad 2:1 multiplexer/demultiplexer bus switch manufactured on a CMOS process. It operates from a single 3.0 V to 5.5 V supply and features a propagation delay of 0.1 ns (100 ps). The device supports data rates up to 933 Mbps with an on-resistance of 2 Ω at 25°C. Quiescent supply current is typically 1 nA. It functions in the industrial temperature range of -40°C to +85°C and is housed in a 16-lead QSOP package.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix against the manufacturer's official guide, as variants such as REEL or REEL7 indicate different packaging formats. Confirm RoHS compliance status if required by project specifications. Ensure the selected part number matches the required temperature range and package type before finalizing procurement orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for applications requiring low insertion loss and minimal signal distortion due to its 2 Ω on-resistance. Consider the bidirectional nature for interfacing between devices with varying voltage levels. Verify that the control logic inputs align with the system's available voltage rails to ensure proper enable/disable functionality without external level shifting.
