ADG774BRQZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG774BRQZ-REEL7 is a monolithic CMOS device comprising four 2:1 multiplexer/demultiplexers with high impedance outputs. It operates from a single 3 V to 5.5 V supply and features a –3 dB bandwidth of 240 MHz. The B version supports an automotive temperature range of –40 °C to +125 °C. Key electrical parameters include a typical on resistance (RON) of 2.2 Ω at 5 V, maximum 89 Ω at 3 V, and on resistance flatness typically less than 0.5 Ω. Switching times are characterized by tON of 7 ns typ and tOFF of 4 ns typ at 5 V. Quiescent supply current is typically 1 nA. The device utilizes a 16-lead Shrink Small Outline Package (QSOP).

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix REEL7 confirms tape and reel packaging rather than tube. Confirm the BRQZ designation indicates lead-free construction and the QSOP package type. Ensure the B version grade matches the required –40 °C to +125 °C automotive temperature range specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for applications requiring wide bandwidth and low distortion for fast signals like USB or Ethernet. Compare against the ADG774ABRQZ if lower on resistance at 3 V is critical, noting the A version has different RON characteristics. Verify that the 16-pin QSOP footprint fits the target PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG774 belongs to Analog Devices' family of CMOS analog switches designed for high-speed signal routing. The BRQZ variant specifically denotes the shrink small outline package form factor. This series is engineered to balance low power consumption with high performance metrics suitable for portable and industrial electronics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG774BRQ is listed as obsolete with direct substitutes available within the same manufacturer portfolio. Verify pinout compatibility before substituting with other quad 2:1 mux devices.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the break-before-make time delay?

The break-before-make time delay (tD) is typically 5 ns and has a minimum guaranteed value of 1 ns under specified test conditions.

How does the on resistance vary with voltage?

The on resistance is typically 2.2 Ω at 5 V and increases to 4 Ω at 3 V, remaining relatively flat across the analog signal range.

Is the device suitable for video signal switching?

Yes, the combination of fast switching speed and high signal bandwidth greater than 200 MHz makes it suitable for video signal switching.
