ADG774BRQ-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG774BRQ-REEL is a monolithic CMOS device comprising four 2:1 multiplexer/demultiplexers with high impedance outputs, housed in a 16-lead Shrink Small Outline Package (QSOP). It operates from a single 3 V to 5.5 V supply and features a typical on resistance of 2.2 Ω with a maximum of 89 Ω at 3 V operation. The device provides a –3 dB bandwidth of 240 MHz and supports rail-to-rail signal ranges. Key dynamic characteristics include a typical turn-on time of 7 ns and turn-off time of 4 ns at 5 V. It exhibits low quiescent supply current of 1 nA typical and break-before-make switching action to prevent channel shorting.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix REEL against the manufacturer's current documentation to confirm reel quantity and packaging specifications. Ensure the QSOP package variant matches the design footprint requirements. Confirm that the B version temperature rating of –40°C to +125°C aligns with the operational environment constraints before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring wide bandwidth and low distortion in portable systems. The 2.2 Ω typical on resistance and 240 MHz bandwidth support high-speed data signals like USB 1.1. Verify that the 16-lead QSOP package fits the available PCB space. Consider the 3 V to 5.5 V single supply operation compatibility with the system voltage rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG774 series includes variants such as ADG774BR and ADG774ABRQZ, which share similar functional architectures but may differ in package types or specific electrical tolerances. The BRQZ designation indicates a lead-free QSOP package. The REEL suffix denotes tape and reel packaging for automated assembly processes.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the ADG774 family include ADG774BRQ and ADG774BRQZ. Check datasheets for pin compatibility and electrical parameter matching, particularly on resistance and bandwidth, when evaluating alternative packages or lead-free versions.
