Product details
Overview
DG428DN-E3 from Vishay Siliconix is a single 8-channel latchable analog multiplexer with on-chip TTL-compatible address latches, 55 Ω typical RDS(on), 160 ns transition time, and ±15 V dual-supply operation - used for precision signal routing in microprocessor-controlled data acquisition systems.
For engineers reviewing the DG428DN-E3 datasheet, DG428DN-E3 pinout, DG428DN-E3 application, or DG428DN-E3 equivalent, this device supports bus-interfaced analog switching with break-before-make action, low charge injection (1 pC), and EN-controlled reset for stacked configurations - critical for high-accuracy, multi-channel sampling architectures.
Technical Context
The DG428DN-E3 integrates silicon-gate CMOS switches with parallel n- and p-channel MOSFETs, level-shifting circuitry, and D-type latches driven by WR/RS control signals. Its architecture enables full rail-to-rail analog conduction (±15 V) while maintaining TTL-compatible digital inputs across –40 °C to +85 °C.
Break-before-make switching prevents momentary crosstalk between adjacent channels; on-board latches eliminate external address storage, reducing board space in bus-controlled systems. The EN pin allows global switch-off for cascading multiple DG428DN-E3 units without shared control logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 55 Ω typical - ensures minimal signal attenuation and voltage drop in precision analog paths |
| tTRANS | 160 ns typical - enables high-throughput sampling at >3 MHz channel-switching rates |
| Charge Injection | 1 pC - limits voltage error in sampled-data systems with ≥1 nF hold capacitors |
| Analog Range | ±15 V - supports full-range bipolar signal routing without clamping or distortion |
| Supply Voltage | ±15 V (dual) or 12 V (single) - provides design flexibility for legacy and modern power architectures |
| Off Isolation | –75 dB at 100 kHz - suppresses inter-channel coupling in multi-signal acquisition |
| Logic Compatibility | TTL - interfaces directly with 5 V microprocessor buses without level-shifting circuitry |
Pinout & Package
20-pin PLCC (Plastic Leaded Chip Carrier) package with 0.050″ lead pitch, 10.03 mm × 10.03 mm body, and exposed thermal pad not electrically connected.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | S1–S8 Analog Inputs | Single-ended source terminals; bidirectional conduction path to common output (pin 11) |
| 9 | GND | Digital ground reference for TTL input logic and latch circuitry |
| 10 | V− | Negative supply rail for analog switch core and level shifter |
| 11 | D (Drain) | Common analog output terminal; connects to selected Sx input when enabled |
| 12 | V+ | Positive supply rail for analog switch core and level shifter |
| 13, 14, 15 | A0, A1, A2 | 3-bit binary address inputs controlling channel selection (0–7) |
| 16 | EN | Enable input; latches are active only when EN = high - enables global reset of all switches |
| 17 | WR | Write control; rising edge captures A0–A2 state into internal latches for transparent or latch mode |
| 18 | RS | Reset input; forces all latches low and disables all switches regardless of other controls |
| 19, 20 | NC | No-connect pins - left unconnected per manufacturer specification |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | 8-channel, no on-chip latches; requires external address register; RDS(on) = 60 Ω typical | Lacks integrated latching - increases component count and timing complexity in microprocessor-bus systems | Choose when latch-free operation or lower cost outweighs board-space savings and simplified interface |
| ADG408BRUZ | 8-channel, no latches; faster tTRANS = 100 ns; RDS(on) = 45 Ω typical; same PLCC-20 package | Requires external latch or FPGA logic for persistent channel selection - unsuitable for direct bus-write architectures | Prefer when speed and on-resistance are prioritized over latch integration and microprocessor compatibility |
Compared with MAX4617ESE+ and ADG408BRUZ, the DG428DN-E3 uniquely combines on-chip latches, TTL compatibility, and break-before-make switching - making it optimal for embedded microprocessor-based data acquisition where minimal external logic and deterministic channel control are required.

FAQ
What is the maximum analog signal voltage range supported by the DG428DN-E3?
The DG428DN-E3 supports a full analog signal range of ±15 V when operated with dual supplies (V+ = +15 V, V− = −15 V). It also functions with single-supply operation up to 12 V (V+ = 12 V, V− = 0 V), maintaining rail-to-rail conduction. Exceeding these voltages risks permanent damage, as the absolute maximum rating is ±44 V referenced to V−.
Does the DG428DN-E3 require external latches for microprocessor interface?
No - the DG428DN-E3 integrates on-chip TTL-compatible address latches controlled by WR and EN pins. When WR transitions high, the current states of A0–A2 are captured and held, eliminating the need for external latch ICs. This simplifies bus interfacing and reduces PCB area in systems like data acquisition controllers.
How does the break-before-make feature improve signal integrity in the DG428DN-E3?
The DG428DN-E3 guarantees a minimum 30 ns break-before-make interval (tOPEN) between channel transitions. This prevents momentary short-circuits between adjacent analog inputs - critical in applications such as sensor multiplexing where crosstalk could corrupt measurements or damage upstream sources.
What is the significance of the 1 pC charge injection specification for the DG428DN-E3?
A charge injection of 1 pC means that less than 1 picocoulomb of net charge is transferred to the output node during switching. In sample-and-hold circuits with a 1 nF capacitor, this results in ≤1 mV voltage error - preserving accuracy in high-resolution data acquisition systems where hold capacitor size and settling time are tightly constrained.
Can the DG428DN-E3 be used in single-supply systems?
Yes - the DG428DN-E3 supports single-supply operation with V+ = 12 V and V− = 0 V. In this configuration, the analog signal range is 0 V to 12 V, and RDS(on) remains within 80–150 Ω. All digital inputs remain TTL-compatible, and the EN/RS/WR control logic functions identically, enabling use in industrial PLCs and portable instrumentation without negative rails.
