Product details
Overview
DG408MY/PR+T from Maxim Integrated is a precision 1-of-8 CMOS analog multiplexer/demultiplexer designed for high-fidelity signal routing in demanding environments. It delivers guaranteed 100Ω max on-resistance, 8Ω max channel-to-channel on-resistance matching, and 15pC max charge injection - enabling accurate sampling in data-acquisition systems operating across -55°C to +125°C. Its rail-to-rail analog signal handling supports ±5V to ±20V dual supplies or +5V to +30V single supply.
For engineers reviewing the DG408MY/PR+T datasheet, DG408MY/PR+T pinout, DG408MY/PR+T application, or DG408MY/PR+T equivalent, key selection criteria include guaranteed on-resistance flatness (9Ω max), low input off-leakage (<5nA at +85°C), TTL/CMOS-compatible digital control, and ESD protection >2000V per MIL-STD-883 Method 3015.7.
Technical Context
The DG408MY/PR+T implements a fully decoded 3-bit address logic (A0/A1/A2) with active-low enable (EN) to select one of eight bidirectional analog channels (S1–S8) to a common drain (D). Its CMOS transmission-gate architecture ensures symmetrical conduction and rail-to-rail signal swing without polarity constraints.
It operates across extended temperature (-55°C to +125°C) with guaranteed performance parameters including 125Ω max rDS(ON) at TA = TMIN to TMAX under ±15V dual supply, and maintains <100nA total off-leakage (IS(OFF)/ID(OFF)) at +85°C - critical for low-drift sample-and-hold and high-impedance sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (rDS(ON)) | 100Ω max at +25°C, ±15V - ensures minimal signal attenuation and gain error in precision gain-setting or sensor front-end paths |
| On-Resistance Matching | 8Ω max between any two channels - enables multichannel measurement systems with consistent channel-to-channel gain and offset |
| Charge Injection | 15pC max - limits voltage glitch and settling error in sample-and-hold circuits using typical 1nF hold capacitors |
| Analog Signal Range | ±10V with ±15V supplies - supports full-rail operation across industrial sensor outputs and DAC ranges |
| Supply Voltage Range | +5V to +30V single or ±5V to ±20V dual - allows direct interface with legacy ±15V op-amp rails and modern 5V/12V systems |
| Input Leakage Current | 5nA max at +85°C - preserves accuracy in high-impedance pH, thermocouple, or piezoelectric sensor conditioning |
| ESD Protection | >2000V per MIL-STD-883 Method 3015.7 - enhances robustness in test equipment and field-deployable instrumentation |
Pinout & Package
DG408MY/PR+T is supplied in a 16-pin SO (Small Outline) package, 3.9mm body width, with standard JEDEC MO-153 footprint and gull-wing leads.

| 2 | EN | Active-low enable; device disabled when high, all switches open regardless of address state |
| 3 | V− | Negative supply rail; must be connected for dual-supply operation or tied to GND for single-supply use |
| 4–7, 9–12 | S1–S4, S5–S8 | Bidirectional analog channel inputs; electrically identical, no preferred directionality |
| 8 | D | Common bidirectional analog output/input terminal; connects to selected Sx channel when enabled |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRUZ | 16-TSSOP, 100Ω max rDS(ON), but only rated −40°C to +85°C; 20pC charge injection (vs. 15pC) | Lacks extended temperature qualification; higher charge injection increases hold-step error in precision S/H | Select ADG408BRUZ only for commercial-temp industrial controls where cost outweighs thermal margin |
| TS5A23157DCUR | 6-pin SC70, dual SPDT, 0.9Ω typical rDS(ON); not pin-compatible, no 8-channel configuration | Requires board redesign; suitable only for low-voltage (1.8–5.5V), low-on-resistance, space-constrained apps | Choose TS5A23157DCUR only for battery-powered portable test gear needing ultra-low Ron and small footprint |
Compared with ADG408BRUZ and TS5A23157DCUR, DG408MY/PR+T uniquely combines extended temperature operation (−55°C to +125°C), guaranteed 8Ω channel matching, and pin compatibility with legacy DG408 footprints - making it the sole option for mil-aero and high-reliability industrial upgrades requiring zero layout change.

FAQ
What is the operating temperature range of the DG408MY/PR+T?
The DG408MY/PR+T is specified for continuous operation from −55°C to +125°C. This extended temperature grade is confirmed in the Ordering Information table and supported by guaranteed electrical characteristics across that full range, including leakage current, on-resistance, and switching timing parameters - making DG408MY/PR+T suitable for aerospace, downhole, and military applications where ambient extremes are routine.
Is DG408MY/PR+T pin-compatible with the original DG408?
Yes, DG408MY/PR+T is a pin-compatible plug-in upgrade for the industry-standard DG408. The pin configuration - including A0/A1/A2 address inputs, EN enable, S1–S8 channel terminals, D common terminal, V+, V−, and GND - matches exactly per the DG408 functional diagram and pin description tables. No PCB layout changes are needed when replacing legacy DG408 variants with DG408MY/PR+T.
What supply voltages can DG408MY/PR+T operate with?
DG408MY/PR+T supports both dual-supply (±5V to ±20V) and single-supply (+5V to +30V) configurations. When using single supply, V− must be connected to GND. The device maintains guaranteed performance across this full range, including 100Ω max on-resistance at +12V single supply and ±15V dual supply - enabling flexible integration into legacy ±15V systems and modern 5V/12V platforms alike.
How does the charge injection specification of DG408MY/PR+T impact sample-and-hold design?
DG408MY/PR+T specifies 15pC max charge injection, directly limiting hold-step error in sample-and-hold circuits. For example, with a standard 1nF hold capacitor, this yields a worst-case voltage glitch of 15mV - sufficient for stable 12-bit acquisition (LSB = 2.44mV at 10V full scale). This value is guaranteed across temperature and supply conditions, allowing deterministic hold capacitor sizing without derating margins.
Does DG408MY/PR+T require external protection diodes for overvoltage tolerance?
No, DG408MY/PR+T does not require external blocking diodes for normal operation within its Absolute Maximum Ratings. However, if power-supply sequencing cannot be controlled (e.g., V+ applied after V−), Maxim recommends adding two small-signal diodes in series with V+ and V− pins - which reduces analog signal range by 1V but preserves DG408MY/PR+T's core low-leakage and low-Ron performance without altering functionality.
