DG303ABK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG303ABK is a TTL-compatible CMOS analog switch featuring two single-pole double-throw (SPDT) channels. It operates within an extended temperature range of -25°C to +85°C and utilizes a 14-lead ceramic dual in-line package (CERDIP). The device supports power supplies ranging from ±5V to ±18V, or a single supply from +10V to +30V. Key electrical specifications include a maximum on-resistance of 50Ω, a turn-on time of 300ns, and a turn-off time of 250ns. Supply current is typically 0.5mA at positive voltage and 10µA at negative voltage.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature rating. Ensure compatibility with existing board layouts by checking pin configurations. Confirm component authenticity through authorized distribution channels to avoid counterfeit parts.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPDT switching is required in space-constrained applications utilizing CERDIP packages. Consider the extended industrial temperature range (-25°C to +85°C) for environments exceeding standard commercial limits. Evaluate the 50Ω on-resistance and 300ns switching speed against system timing requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG300A-DG303A family of TTL-compatible CMOS analog switches manufactured by Maxim Integrated, now part of Analog Devices Inc. The series combines low power operation with fast switching times and superior DC and AC characteristics suitable for battery-powered circuitry.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG303ACK serves as a direct replacement variant within the same family, sharing identical electrical specifications but differing only in the operating temperature range (0°C to +70°C instead of -25°C to +85°C).
