Product details
Overview
DG444CJ from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) analog switch IC designed for precision signal routing in bipolar and single-supply systems. It features 85Ω max on-resistance, 4Ω max on-resistance matching between channels, <5nA off-leakage at +85°C, 10pC max charge injection, and rail-to-rail analog signal handling up to ±15V. It is used in test equipment, audio signal routing, and military radios where low distortion and channel-to-channel consistency are critical.
For engineers reviewing the DG444CJ datasheet, DG444CJ pinout, DG444CJ application, or DG444CJ equivalent, key selection considerations include its NC logic configuration, 16-pin plastic DIP package, guaranteed RON flatness (9Ω max), TTL/CMOS-compatible control inputs, and operation across ±4.5V to ±20V or +10V to +30V supplies.
Technical Context
The DG444CJ implements four independent SPST switches with normally closed topology, controlled by active-low logic inputs (IN1–IN4). Its silicon-gate 44V process enables robust bipolar supply operation and low leakage over temperature. The device guarantees matched on-resistance (≤4Ω) and flat on-resistance (≤9Ω) only under bipolar-supply conditions, with analog signal range spanning ±15V.
Switching performance is characterized by tON < 250ns and tOFF < 70ns at ±16.5V supplies, while dynamic parameters include 100dB crosstalk rejection and 60dB off-isolation at 1MHz. Charge injection (≤10pC) and low power consumption (≤35µW) support high-fidelity sample-and-hold and battery-operated applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4674CPE+ | Quad SPST, normally open (NO), 60Ω RON, 16-pin PDIP, −40°C to +85°C | Requires inverted logic drive; lower RON but no NC default state | Select when NO behavior and wider temp range are required; verify logic polarity compatibility |
| ADG1414BNZ | Quad SPST, NC, 9Ω RON, 16-pin PDIP, −40°C to +125°C, 30V max supply | Lower RON and wider temperature range, but higher charge injection (15pC) | Prefer for ultra-low RON designs where 15pC charge injection is acceptable |
Compared with DG444CJ, MAX4674CPE+ offers lower on-resistance and extended temperature range but lacks NC default behavior, while ADG1414BNZ provides significantly lower RON and broader thermal operation at the cost of higher charge injection-critical for sample-and-hold fidelity.

FAQ
What is the logic configuration of the DG444CJ?
The DG444CJ is a quad, normally closed (NC) SPST analog switch: each switch conducts by default when its IN pin is logic low (0V), and opens when IN is logic high (≥2.4V). This NC behavior ensures signal continuity during power-down or logic faults, making DG444CJ suitable for fail-safe routing in critical systems like military radios and test instrumentation.
Does the DG444CJ support single-supply operation?
Yes, the DG444CJ supports single-supply operation from +10V to +30V, with V− tied to ground. In this mode, the analog signal range is 0V to V+, and VL must be connected to +5V for TTL compatibility. However, key specifications-including RON matching (4Ω max) and RON flatness (9Ω max)-are guaranteed only under bipolar-supply conditions (±4.5V to ±20V).
What is the maximum analog signal voltage the DG444CJ can handle?
The DG444CJ supports an analog signal range of ±15V when operated with ±15V supplies. Absolute maximum ratings allow V+ up to +44V and V− down to −44V (referenced to V−), but the usable linear signal range remains bounded by the supply rails. Exceeding ±15V on S/D pins risks exceeding the specified RON flatness and leakage performance.
How does the DG444CJ compare to the DG445CJ?
The DG445CJ is the normally open (NO) counterpart to the DG444CJ: both share identical package, temperature grade (0°C to +70°C, 16-pin DIP), electrical specs (RON, leakage, charge injection), and pinout-but differ in default switch state. DG444CJ closes on logic low; DG445CJ opens on logic low. System designers select DG444CJ when default conduction is required, such as in safety-critical signal paths.
Is the DG444CJ RoHS compliant?
Yes, the DG444CJ (plastic DIP package) is RoHS compliant per Maxim's product change notices and packaging documentation. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and meets EU Directive 2011/65/EU requirements for restriction of hazardous substances in electrical and electronic equipment.
