Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the packaging format and lead-free status. The REEL7 designation indicates tape and reel packaging intended for automated assembly processes. Ensure compatibility with standard surface mount placement equipment. Confirm that the component meets RoHS directives if required by your manufacturing standards. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single channel SPST configuration is required within tight space constraints. The 6-lead SC-70 package offers a small footprint ideal for dense PCB layouts. Consider the 2 Ω on resistance for applications demanding minimal signal attenuation. Verify that the 1.8 V minimum supply voltage aligns with your system's power architecture. Evaluate the 200 MHz bandwidth against your highest frequency signal requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG741/ADG742 family of low voltage CMOS switches. The ADG742 variant specifically denotes the SPST configuration, distinct from the multiplexer structure found in other series members. It shares the same physical package and electrical characteristics as the ADG741 but differs in internal logic configuration. The family is designed for general-purpose switching applications requiring high speed and low power consumption.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional equivalents within the same package include the ADG741BKSZ-REEL7. Other Analog Devices parts in the SC-70 form factor may serve as alternatives if pinout compatibility is maintained. Verify that substitute components meet the same 200 MHz bandwidth and 1.8 V to 5.5 V supply specifications.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum analog signal range supported by the ADG742?

The analog signal range extends from ground (0 V) to the positive supply voltage (VDD), enabling rail-to-rail operation.

How does the on resistance vary with temperature?

The on resistance remains relatively stable across the industrial temperature range of −40°C to +85°C, with a maximum specified value of 4 Ω at 25°C and up to 6 Ω at lower temperatures depending on the supply voltage.

Is the device sensitive to electrostatic discharge?

Yes, the ADG742 is an ESD-sensitive device. Although it includes proprietary protection circuitry, proper handling precautions are necessary to prevent permanent damage or performance degradation.
