DG381CJ

Overview

The DG381CJ is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates with a single supply voltage ranging from 10 V to 30 V or dual supplies from ±5 V to ±18 V. The device features a maximum on-resistance of 50 Ohms and supports a DC switch current of 30 mA. Switching times are specified at a maximum of 300 ns for turn-on and 250 ns for turn-off. It is housed in a 14-pin PDIP package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

Dual SPST configuration providing independent signal path control
CMOS technology enabling low power consumption and high input impedance
Single and dual supply compatibility for flexible system integration

Applications

General-purpose analog signal routing
Data acquisition systems
Audio switching applications

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Check RoHS compliance documentation as the standard version may not meet current environmental regulations. Confirm package integrity upon receipt, as older PDIP units may exhibit handling wear. Validate datasheet revisions against specific design requirements before final procurement decisions.

Selection Notes

Select this component when dual isolated analog channels are required in a DIP package. Ensure supply voltages remain within the 10 V to 30 V single or ±5 V to ±18 V dual ranges. Verify that the 50 Ohm on-resistance meets circuit loss tolerances. Consider thermal dissipation limits if operating near maximum current specifications.

Part Context

This part belongs to the DG381A series of general-purpose analog switches. It shares functional similarities with other Maxim Integrated CMOS switches but is distinguished by its specific PDIP packaging and dual-channel layout. The series is designed for cost-effective signal switching in industrial and consumer electronics.
