Product details
Overview
DG409DJZ from Renesas Electronics is a differential 4-channel CMOS analog multiplexer with bilateral signal switching, 100Ω max ON resistance at ±15V supplies, <250ns transition time, and operation across -40°C to +85°C for data acquisition and audio routing applications.
For engineers reviewing the DG409DJZ datasheet, DG409DJZ pinout, DG409DJZ application, or DG409DJZ equivalent, this page delivers verified specifications, package mapping, real-world use scenarios, and validated alternative options for industrial and test equipment design.
Technical Context
The DG409DJZ implements a TTL/CMOS-compatible 2-bit decode logic (A0/A1) controlling four matched differential switch pairs (S1A/S1B through S4A/S4B), each with symmetrical ON-resistance and low charge injection (20pC typ). It features independent enable (EN) control and internal 5V reference for stable logic thresholds.
Designed as a drop-in upgrade for DG509A, it uses high-voltage silicon-gate process to achieve lower rDS(ON) variation (<15Ω matching), reduced latch-up risk via epitaxial isolation, and dual-supply support from ±5V to ±20V or single +5V to +34V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Max ON Resistance | 100Ω at ±15V - ensures minimal signal attenuation in precision analog paths |
| Transition Time | <250ns - enables fast channel switching in automated test systems |
| Charge Injection | 20pC typ - reduces error in sample-and-hold circuits without added compensation |
| Analog Signal Range | ±15V (bipolar) or 0–12V (single supply) - supports wide dynamic range sensing |
| Supply Voltage Range | ±5V to ±20V or +5V to +34V - accommodates legacy and modern rail requirements |

Pinout & Package
Package: 16-lead PDIP (Plastic Dual-In-Line), Pb-free, RoHS-compliant (PKG DWG # E16.3), suitable for through-hole wave solder only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, A0 | Logic Decode Input (LSB) | Selects channel pair 0–3 when combined with A1; drives internal decoder |
| 2, EN | Enable Input | High-active control: disables all switches when low, enabling multi-device bus sharing |
| 3, V− | Negative Supply Terminal | Bias reference for analog path; must be ≤ V+ − 44V per absolute max rating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG409BRZ | 16-lead SOIC; 75Ω max rDS(ON); 180ns tTRANS; requires ±15V or +12V single supply | Lower ON resistance but no PDIP option; higher leakage (10nA max ID(OFF)) at full temp range | Preferred for space-constrained PCBs where SOIC fits and tighter rDS(ON) tolerance is critical |
| MAX4052ACPP+ | 16-lead PDIP; 120Ω max rDS(ON); 200ns tTRANS; ±15V or +5V to +30V supply | Higher ON resistance and wider rDS(ON) spread (ΔrDS(ON) = 35Ω); same pinout but different truth table (active-low EN) | Acceptable for cost-sensitive designs where 120Ω rDS(ON) and inverted EN logic are acceptable |
Compared with ADG409BRZ and MAX4052ACPP+, the DG409DJZ offers superior channel matching (≤15Ω ΔrDS(ON)), industry-standard PDIP packaging, and guaranteed 100Ω rDS(ON) performance across −40°C to +85°C - making it optimal for legacy-compatible, high-precision analog routing.

FAQ
What is the maximum analog signal voltage range supported by the DG409DJZ?
The DG409DJZ supports an analog signal range of ±15V under bipolar supply conditions (V+ = +15V, V− = −15V) and 0–12V under single-supply operation (V+ = 12V, V− = 0V). These ranges are specified in the Electrical Specifications table on page 4 of the FN3283 datasheet and reflect the device's ability to pass signals without distortion or clipping within those bounds. The DG409DJZ maintains low ON-resistance and low leakage across these full ranges.
Does the DG409DJZ require external pull-up resistors on its digital control lines?
No, the DG409DJZ does not require external pull-up resistors on A0, A1, or EN. Its digital inputs are TTL/CMOS compatible with guaranteed logic thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) and low input current (±10μA max), allowing direct connection to microcontroller GPIOs or FPGA outputs. The internal 5V reference and protection diodes eliminate the need for external biasing - confirmed in the "Digital Input Characteristics" section of the FN3283 datasheet.
Can the DG409DJZ be used with a single +5V supply?
Yes, the DG409DJZ operates with a single +5V supply (V+ = +5V, V− = 0V), supporting analog signals from 0V to approximately +3.5V. While the datasheet specifies full performance (e.g., 100Ω rDS(ON), <250ns tTRANS) at ±15V or +12V, the Absolute Maximum Ratings confirm V+ to V− ≤ 44V and minimum functional supply of +5V. Page 5 lists single-supply test conditions confirming functionality at +12V; +5V operation is viable but may increase rDS(ON) and reduce bandwidth.
What is the thermal resistance (θJA) of the DG409DJZ in its PDIP package?
For the DG409DJZ in its 16-lead PDIP package (PKG DWG # E16.3), the typical junction-to-ambient thermal resistance (θJA) is 90°C/W, as specified in the "Thermal Information" table on page 4 of the FN3283 datasheet. This value assumes mounting on an evaluation PCB in free air and is critical for calculating junction temperature rise under load - for example, at 1mA channel current and 100Ω rDS(ON), power dissipation remains well below thermal limits even at +85°C ambient.
How does the DG409DJZ differ from the DG408DJZ in terms of channel architecture?
The DG409DJZ implements a differential 4-channel architecture (four matched switch pairs: S1A/S1B through S4A/S4B feeding two outputs DA and DB), whereas the DG408DJZ is a single-ended 8-channel multiplexer (eight inputs S1–S8 feeding one output D). This structural difference makes the DG409DJZ ideal for noise-immune differential signaling, while the DG408DJZ suits unbalanced, high-channel-count routing. Pinouts, truth tables, and internal decode logic are distinct - confirmed in Figures 1A/B and Truth Tables on pages 2–3 of FN3283.
