DG508BEY-T1-E3 contains a single 8-channel multiplexer/demultiplexer and is a member of the DG508 family of CMOS multiplexers/demultiplexers. This device is especially well suited for analog and digital switching applications.

Application Field

The DG508BEY-T1-E3 is used in applications where the input signal needs to be multiplexed from an analog source to a single output. The channels can be individually set to either a low state logic (GND) or high logic level (VCC) and enabled with a logic low pulse on the channel select pins.

This particular IC also includes an enable pin (EN) which allows users to turn off all analogue switches in the IC with a single signal. This efficiency can be useful in situations where noise immunity is important, and this IC is often used in low power circuits where its low ON resistance helps conserve energy.

Working Principle

The DG508BEY-T1-E3 consists of eight independent, single-pole/single-throw (SPST) analog switches. These switches are designed to provide low ON resistance and fast switching times in order to support different applications.

The device works by connecting the input pins to a common output pin. The channel select pin determines which pin is connected to the output. When a logic low pulse is applied to the select pin, the corresponding switch closes, allowing a signal to pass from the input to the output.

The on-resistance (R_ON) of the switch is typically low, and is constant over the temperature range of the device being used. This is desirable in applications where precision is important.

The enable pin can be used to disable all switches in one go. This can be useful in situations where noise immunity is important since the disabled chips will not be transmitting any signals while they are in a disabled state.

Conclusion

The DG508BEY-T1-E3 is a low-power CMOS analog multiplexer/demultiplexer with an enable pin. This IC is especially well suited for analog and digital switching applications where low on-resistance is required for precision switching. It has a low on-resistance which is constant over the temperature range and is suitable for applications where noise immunity is important.
