DG308ABK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG308ABK is a quad SPST analog switch manufactured by Harris Corporation, now part of Analog Devices. It features four independent single-pole single-throw switches within a single package. The device operates on dual power supplies ranging from ±15V to ±20V. Key electrical parameters include a maximum on-resistance of 100 ohms and a maximum on-resistance matching of 10 ohms. The switch exhibits a maximum turn-on time of 200 ns and a turn-off time of 150 ns. It supports a leakage current of up to 10 nA at +25°C. The component is designed for operation across an industrial temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer source carefully as Harris Corporation assets were acquired by Analog Devices. Confirm the specific suffix 'BK' matches your required package variant. Check for obsolescence status since legacy components may have limited availability. Ensure the datasheet aligns with the intended voltage and speed requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent analog switches are required in a compact form factor. Verify that the ±15V to ±20V supply range fits your system design. Consider the 100 ohm on-resistance limit for signal loss calculations. Compare against modern equivalents if long-term supply stability is a primary concern.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG308 family of quad analog switches. These devices are commonly used in instrumentation where multiple signal lines need to be routed or switched. The technology represents standard bipolar CMOS processes typical for analog switching applications requiring low distortion and high isolation.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Analog Devices offers updated versions such as the ADG308 series. Verify pin compatibility before substitution. Check if newer packages offer improved thermal performance or lower on-resistance.
