Product details
Overview
DG408MY/PR from Maxim Integrated is a high-reliability, 1-of-8 CMOS analog multiplexer/demultiplexer designed for precision signal routing in harsh environments. It features guaranteed 100Ω max on-resistance, 8Ω max channel-to-channel matching, 15pC max charge injection, and operates across -55°C to +125°C with ±5V to ±20V dual supplies or +5V to +30V single supply. It serves in aerospace guidance systems requiring rail-to-rail analog signal handling and low leakage.
For engineers reviewing the DG408MY/PR datasheet, DG408MY/PR pinout, DG408MY/PR application, or DG408MY/PR equivalent, this page delivers verified electrical specs, thermal-grade package details (16-pin SO), functional truth table alignment, and direct alternatives for extended-temperature analog switching designs.
Technical Context
The DG408MY/PR implements a CMOS transmission-gate architecture with integrated decoder logic, enabling single-ended 8:1 analog signal selection via three address lines (A0–A2) and an active-low enable (EN). Its switch design guarantees monotonic on-resistance flatness (9Ω max) over the full ±10V analog range under ±15V supplies.
It supports bidirectional signal flow with rail-to-rail analog voltage handling (±20V dual, +30V single), TTL/CMOS-compatible digital control inputs, and ESD protection exceeding 2000V per MIL-STD-883 Method 3015.7 - critical for avionics and industrial test equipment where supply sequencing and transient immunity are non-negotiable.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRZ | 100Ω typical RON, but only specified over -40°C to +85°C; no guaranteed 8Ω channel matching | Not qualified for -55°C or +125°C operation; lacks MIL-STD-883 ESD validation | Select DG408MY/PR when extended temperature range and guaranteed matching are mandatory |

FAQ
What is the maximum allowable supply voltage for DG408MY/PR in dual-supply mode?
The DG408MY/PR supports dual-supply operation from ±5V to ±20V. Absolute maximum ratings specify V+ up to 44V referenced to V−, but functional operation is guaranteed only within the ±5V to ±20V range. Exceeding ±20V risks violating the guaranteed on-resistance flatness and leakage specifications, and may compromise long-term reliability in extended-temperature applications.
Does DG408MY/PR support single-supply operation, and how is it configured?
Yes, DG408MY/PR operates with a +5V to +30V single supply. To configure, tie V− to GND and apply the positive supply to V+. The analog signal range then extends from 0V to V+, preserving rail-to-rail functionality. Digital inputs remain TTL/CMOS-compatible, and all key specs-including 100Ω max RON and 15pC max charge injection-remain valid per the datasheet's single-supply characterization.
Is DG408MY/PR pin-compatible with the original DG408, and what does that mean for legacy designs?
Yes, DG408MY/PR is explicitly documented as a pin-compatible plug-in upgrade for the industry-standard DG408. This means identical 16-pin SO footprint, matching pin functions (A0–A2, EN, S1–S8, D, V+, V−, GND), and backward-compatible timing and logic thresholds. No PCB layout changes or firmware modifications are required to upgrade from legacy DG408 variants to DG408MY/PR.
What is the significance of "guaranteed 8Ω max channel matching" for DG408MY/PR?
Guaranteed 8Ω max channel matching means the difference between the highest and lowest on-resistance values across all eight switched channels remains ≤8Ω under specified conditions (e.g., ±15V supplies, TA = TMIN to TMAX). This ensures consistent gain and offset behavior when sequentially measuring multiple sensors - critical for ratiometric bridge measurements, multi-channel thermocouple cold-junction compensation, and calibrated test equipment where channel-to-channel uniformity directly impacts measurement accuracy.
How does the -55°C to +125°C temperature rating of DG408MY/PR impact its use in automotive or aerospace applications?
The -55°C to +125°C rating qualifies DG408MY/PR for under-hood automotive ECUs, jet engine monitoring systems, and satellite payload electronics where ambient temperatures exceed commercial or industrial grade limits. Unlike standard-grade muxes, DG408MY/PR maintains guaranteed leakage (<5nA at +85°C), on-resistance flatness (9Ω max), and ESD robustness (>2000V) across this full range - eliminating derating assumptions and enabling first-pass design success in thermally aggressive environments.
