Analog Switches, Multiplexers, Demultiplexers datasheet and documents for DG421CJ

DG421CJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG421CJ is a dual single-pole/single-throw (SPST) CMOS analog switch featuring latchable logic inputs. It operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. The device guarantees an on-resistance of 35Ω maximum, with a typical value of 20Ω. On-resistance matching between channels is limited to 45Ω maximum, and on-resistance flatness is 5Ω maximum. Charge injection is capped at 15pC, while off-leakage current remains below 10nA across the operating temperature range. Switching times are specified as 250ns for turn-on and 200ns for turn-off. The component is housed in a 16-pin Plastic DIP package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Features latchable logic inputs compatible with TTL and CMOS standards to simplify microprocessor interfacing.
Provides rail-to-rail signal handling capabilities using a silicon-gate process.
Ensures low power consumption suitable for battery-operated applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CJ' corresponds to the 16-pin Plastic DIP package and the 0°C to +70°C commercial temperature grade. Confirm that the ordering information matches the manufacturer's current datasheet revision, as legacy Maxim Integrated products may have transitioned specifications under Analog Devices Inc. management.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPST switching with latched control signals is required. Ensure the application utilizes bipolar supplies or a single supply within the +10V to +30V range. Verify that the 45Ω maximum on-resistance match meets system requirements, as tighter matching is not guaranteed by this specific part number.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG421CJ belongs to the DG421/DG423/DG425 family of improved low-power CMOS analog switches. While the DG423 offers SPDT configurations and the DG425 provides DPST switches, the DG421 specifically contains two independent SPST switches. All variants share the same latchable input architecture and general electrical characteristics.
