DG303ABWE

Analog Switches, Multiplexers, Demultiplexers Overview

The DG303ABWE is a TTL-compatible CMOS analog switch featuring two single-pole double-throw (SPDT) channels in a 16-lead wide SOIC package. It operates with dual supplies from ±5V to ±18V or a single supply of +10V to +30V. The device provides an on-resistance of less than 50Ω, which remains constant over the analog signal range. Key electrical parameters include a maximum turn-on time of 300ns and a maximum turn-off time of 250ns at +25°C. Charge injection is typically 12pC. The component supports continuous currents up to 30mA and functions within a temperature range of -25°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm pinout compatibility and environmental ratings. Confirm that the 16-lead Wide SOIC package dimensions match the target PCB footprint. Ensure the selected variant meets the required operating temperature range for the intended deployment environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPDT switching is required with low power consumption and fast response times. Verify that the analog signal voltage range falls within the specified V+ to V- limits. Consider the thermal dissipation capabilities of the Wide SOIC package if multiple switches are active simultaneously under load.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG300–DG303A family of TTL-compatible CMOS analog switches. These devices share electrical characteristics and pin configurations with original manufacturer equivalents. The 'B' suffix indicates an extended industrial temperature range compared to commercial variants.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG303ACWE serves as a direct replacement for lower temperature requirements. Other members of the DG300 series may be compatible depending on the specific channel configuration needed.
