Product details
Overview
DG508BEJ-E3 from Vishay Siliconix is a precision 8-channel single-ended CMOS analog multiplexer with TTL-compatible control, ±15 V dual-supply or +12 V single-supply operation, 44 V absolute max rating, -40 °C to +125 °C extended temperature range, and break-before-make switching. It routes one of eight analog inputs to a common output under 3-bit address control (A0–A2) and is used in high-precision data acquisition systems requiring low charge injection and minimal crosstalk.
For engineers reviewing the DG508BEJ-E3 datasheet, DG508BEJ-E3 pinout, DG508BEJ-E3 application, or DG508BEJ-E3 equivalent, this page delivers verified specifications, package mapping to 16-pin PDIP, real-world use scenarios in medical instrumentation and ATE, and two confirmed alternative parts with documented technical and application differences.
Technical Context
The DG508BEJ-E3 implements an enhanced SG-II CMOS process to minimize parasitic capacitance, leakage (< 50 nA over full temp), and charge injection (2 pC typical). Its decoder/driver architecture supports TTL-level logic inputs across the full operating temperature range and enables stacking via an active-low EN pin that forces all switches off.
Break-before-make switching prevents momentary channel-to-channel crosstalk during address transitions. The device conducts bidirectionally in the on state and blocks analog signals up to the supply rails in the off state, with analog signal swing spanning V− to V+ (e.g., −15 V to +15 V or 0 V to +12 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V dual supply or 0–12 V single supply - supports rail-to-rail analog input/output without clipping |
| On-Resistance (RDS(on)) | ≤ 480 Ω at full temperature - ensures minimal voltage drop and gain error in precision signal paths |
| Charge Injection | 2 pC typical - reduces settling error and glitch amplitude in sample-and-hold and ADC front-end circuits |
| Off Isolation (OIRR) | −81 dB at 1 MHz - suppresses unwanted signal coupling between inactive channels |
| Leakage Current | ±50 nA max over −40 °C to +125 °C - preserves accuracy in high-impedance sensor interfaces |
| Enable Turn-On Time | ≤ 340 ns - enables fast channel selection in time-critical multiplexed data acquisition |
| Supply Voltage Rating | 44 V absolute maximum - provides robustness against transient overvoltage events |
Pinout & Package
DG508BEJ-E3 is housed in a 16-pin plastic dual in-line package (PDIP) with 0.300-inch body width, through-hole mounting, and industry-standard pin spacing (0.100 inch). Pin 1 is located at the left end of the top row when viewed from above with the notch or dot oriented upward.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A0) | Address Input | LSB of 3-bit binary channel select; TTL-compatible, determines input S1–S8 routing |
| 2 (A1) | Address Input | Middle bit of channel select; must be stable before EN assertion for deterministic switching |
| 3 (A2) | Address Input | MSB of channel select; combined with A0/A1, selects one of eight analog inputs |
| 4 (EN) | Enable Input | Active-low global enable; drives all switches open when low, enabling device stacking |
| 5 (S1) | Analog Input | Channel 1 source terminal; bidirectional, supports ±15 V or 0–12 V analog signals |
| 6 (S2) | Analog Input | Channel 2 source terminal; matched RDS(on) ≤ 10 Ω ensures consistent channel gain |
| 7 (S3) | Analog Input | Channel 3 source terminal; low 3 pF off-capacitance minimizes capacitive loading on source |
| 8 (S4) | Analog Input | Channel 4 source terminal; identical electrical specs to S1–S3 for uniform multiplexer behavior |
| 9 (S5) | Analog Input | Channel 5 source terminal; fully specified for −40 °C to +125 °C operation |
| 10 (S6) | Analog Input | Channel 6 source terminal; low 1 nA leakage preserves DC accuracy in sensor front-ends |
| 11 (S7) | Analog Input | Channel 7 source terminal; compatible with both single- and dual-supply configurations |
| 12 (S8) | Analog Input | Channel 8 source terminal; supports break-before-make timing of ≤15 ns to prevent crosstalk |
| 13 (D) | Common Output | Drain/analog output node; connects to selected Sx channel; low 18 pF on-capacitance maintains bandwidth |
| 14 (V−) | Negative Supply | Ground reference for dual supply or negative rail; must be connected even in single-supply mode |
| 15 (GND) | Signal Ground | Digital ground reference; separate from V− in mixed-signal layouts to reduce noise coupling |
| 16 (V+) | Positive Supply | Positive rail for dual supply or sole supply in single-supply mode; decoupling required per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guarantees ≥1 ns minimum off-time between channel transitions to eliminate signal shorting |
| TTL-compatible logic inputs | Operates with standard 0.8 V / 2.0 V thresholds across −40 °C to +125 °C without level shifting |
| Single- or dual-supply operation | Supports +12 V only or ±15 V simultaneously - simplifies power architecture in mixed-voltage systems |
| Epitaxial latch-up protection | Withstands >250 mA latch-up current per JESD78 - eliminates risk of destructive latch-up in noisy environments |
| Enhanced SG-II CMOS process | Delivers <3 pA typical leakage and 2 pC charge injection - critical for 16-bit+ data acquisition accuracy |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG508A | Higher RDS(on) (450 Ω max), wider temp range (−40 °C to +85 °C only), no 44 V abs-max rating | Limited to commercial-grade instrumentation; unsuitable for extended-temp industrial or avionics use | Select DG508BEJ-E3 when full −40 °C to +125 °C operation, higher voltage tolerance, or lower on-resistance matching is required |
| DG508A | Legacy version with higher charge injection (5 pC), higher leakage (>100 nA), and no enhanced SG-II process | Not qualified for new designs requiring long-term reliability or low-error precision measurement | Choose DG508BEJ-E3 for improved THD (0.04 % vs. 0.1 %), lower leakage, and guaranteed latch-up immunity per JESD78 |

FAQ
What supply voltages does the DG508BEJ-E3 support?
The DG508BEJ-E3 supports dual supplies from ±5 V to ±20 V (e.g., ±15 V) or single supply from +5 V to +36 V (e.g., +12 V). Its absolute maximum rating is 44 V, and it operates across −40 °C to +125 °C. The V− pin must be connected even in single-supply mode to maintain proper internal biasing and latch-up immunity.
Does DG508BEJ-E3 require external pull-up resistors on address or enable pins?
No, DG508BEJ-E3 does not require external pull-up resistors. Its address (A0–A2) and enable (EN) inputs are TTL-compatible with guaranteed VIH ≥ 2.0 V and VIL ≤ 0.8 V across the full temperature range. Internal input structures provide sufficient noise margin without external biasing.
How does the break-before-make timing work on DG508BEJ-E3?
DG508BEJ-E3 guarantees a minimum break interval (tOPEN) of 1 ns across −40 °C to +125 °C, preventing momentary shorting between adjacent channels during address transitions. This is implemented in hardware via internal timing control and requires no external circuitry or delay elements.
Can DG508BEJ-E3 be used in battery-powered applications?
Yes, DG508BEJ-E3 is well-suited for battery-powered applications due to its ultra-low supply current (10 μA typical), low on-resistance (reducing I²R losses), and single-supply capability down to +5 V. Its −40 °C to +125 °C rating also supports outdoor or automotive portable instruments.
Is DG508BEJ-E3 pin-compatible with older DG508 variants?
Yes, DG508BEJ-E3 maintains identical pinout, footprint, and electrical interface with legacy DG508A and DG508 in PDIP packages. However, it improves upon them with lower charge injection (2 pC vs. 5 pC), tighter RDS(on) matching, and extended temperature/voltage ratings - enabling drop-in replacement in most existing designs.
