DG301A/BCA

Analog Switches, Multiplexers, Demultiplexers Overview

The DG301A/BCA is a single-channel SPDT analog switch manufactured by Rochester Electronics, LLC. It utilizes CMOS technology and is housed in a 10-pin metal can package (MBCY-10). The device operates with a nominal supply voltage of ±15 V, supporting a range from -15 V to +15 V. Key electrical parameters include a maximum on-resistance (Ron) of 75 Ω and a maximum turn-on time of 300 ns. It features break-before-make switching action. The component is rated for an operating temperature range of -55 °C to 125 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Single-pole double-throw (SPDT) signal routing capability within a compact metal can package.
• CMOS construction ensures low power consumption and high input impedance.
• Break-before-make switching action prevents signal shorting during channel transitions.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring isolated signal paths.
• Multiplexing applications in industrial instrumentation.
• Test and measurement equipment signal routing.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix BCA against the manufacturer's datasheet to confirm pinout compatibility and package dimensions. Ensure the procurement source provides traceability documentation, as this part may be a lifecycle-managed product. Confirm that the metal can package meets the environmental sealing requirements for the intended deployment environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single SPDT switch with robust metal packaging is required for harsh environments. The 75 Ω on-resistance and 300 ns switching speed define its performance limits. Compare against plastic-packaged variants if weight or cost is a primary constraint, noting that the metal can offers superior thermal dissipation and shielding characteristics.

Analog Switches, Multiplexers, Demultiplexers Part Context

Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find integrated circuits. The DG301A/BCA is likely a continuation of a legacy Intersil or Harris design. This part belongs to the DG301 family of analog switches, which are widely used in legacy industrial and military applications requiring reliable signal switching.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include the DG301AAA or DG301ABA. Verify that the substitute maintains the same MBCY-10 metal can footprint and pin configuration. Ensure the replacement supports the required ±15 V supply and temperature range specifications.
