Product details

Overview

DG428DJ-E3 from Vishay Siliconix is a single 8-channel latchable analog multiplexer IC designed for microprocessor-controlled data acquisition systems. It features TTL-compatible address latches, break-before-make switching, 55 Ω on-resistance, 160 ns transition time, and ±15 V dual-supply operation - enabling precise channel selection in test equipment and avionics signal routing.

For engineers reviewing the DG428DJ-E3 datasheet, DG428DJ-E3 pinout, DG428DJ-E3 application, or DG428DJ-E3 equivalent, this device supports bus-interfaced analog switching with latch retention, low charge injection (1 pC), high off-isolation (–75 dB), and robust rail-to-rail analog signal handling up to ±15 V.

Technical Context

The DG428DJ-E3 integrates on-chip TTL-compatible address latches, level shifters, and CMOS transmission gates built with parallel n- and p-channel MOSFETs. Its logic interface operates from an internal +5 V reference, decoupling digital control from analog supply rails.

Break-before-make timing (30 ns min) prevents crosstalk during channel transitions; enable (EN) and reset (RS) pins allow system-level stacking and synchronous initialization. All control inputs (A0–A2, EN, WR, RS) meet full-temperature-range TTL voltage thresholds (VAL ≤ 0.8 V, VAH ≥ 2.4 V).

Key Specifications

Parameter	Value and Actual Design Meaning
Channel Count	8 single-ended analog channels with common output
R_DS(on)	55 Ω typical at ±15 V supplies - ensures minimal signal attenuation and gain error in precision measurement paths
t_TRANS	160 ns typical - enables high-throughput sampling in automated test equipment (ATE) at >3 MHz channel-switching rates
Charge Injection	1 pC typical - limits voltage glitch on sampled capacitive nodes, critical for ADC front-end accuracy
Off Isolation	–75 dB at 100 kHz - suppresses crosstalk between inactive and active channels in multi-signal systems
Analog Range	±15 V (dual supply) or 0–12 V (single supply) - supports industrial sensor interfaces and bipolar signal conditioning
Supply Voltage Range	±5 V to ±20 V (dual); 5–20 V (single) - accommodates legacy and modern supply architectures without level-shifting

Pinout & Package

Package: 18-pin plastic DIP (Dual-In-Line), 0.300" wide body per Vishay Doc #71263. Pin pitch: 1.27 mm (0.050"), row spacing: 7.62 mm (0.300"). RoHS-compliant, halogen-free construction.

Pin	Circuit Role	Design Meaning
1 (S1)	Analog Input 1	First of eight bidirectional analog input terminals; conducts equally in both directions when selected
2 (S2)	Analog Input 2	Second analog input; shares common drain (D) output path with S1–S8
3 (S3)	Analog Input 3	Third analog input; fully isolated from other channels when off (±100 nA leakage max)
4 (S4)	Analog Input 4	Fourth analog input; supports rail-to-rail signal swing up to V+ and V−
5 (S5)	Analog Input 5	Fifth analog input; clamped by internal diodes if driven beyond supply rails
6 (S6)	Analog Input 6	Sixth analog input; matched R_DS(on) within 5% across all channels ensures consistent gain
7 (S7)	Analog Input 7	Seventh analog input; low off-capacitance (11 pF) minimizes loading on high-Z sources
8 (S8)	Analog Input 8	Eighth analog input; identical electrical characteristics to S1–S7
9 (D)	Common Analog Output	Bidirectional output node shared by all eight channels; connects to ADC, amplifier, or signal processor
10 (GND)	Digital Ground Reference	Logic ground for TTL-compatible inputs; separate from analog ground in mixed-signal layouts
11 (V−)	Negative Supply Rail	Connects to negative analog supply (e.g., –15 V); defines lower bound of analog signal range
12 (V+)	Positive Supply Rail	Connects to positive analog supply (e.g., +15 V); defines upper bound of analog signal range
13 (A0)	Address Bit 0	LSB of 3-bit binary address; latched on rising edge of WR to select channel 0–7
14 (A1)	Address Bit 1	Middle bit of 3-bit address; transparent when WR = low, latched when WR transitions high
15 (A2)	Address Bit 2	MSB of 3-bit address; determines channel 4–7 vs. 0–3; requires t_S ≥ 100 ns setup before WR
16 (EN)	Enable Control	Active-high latch enable; ties address latches to WR; allows hardware reset of all switches to OFF state
17 (WR)	Write Strobe	Edge-triggered latch control; rising edge captures A0–A2 and EN states for channel selection
18 (RS)	Reset Strobe	Active-high master reset; clears all latches regardless of WR/EN state, forcing all switches OFF

Key Features

Feature	Design Value
On-board TTL-compatible address latches	Eliminates external latch ICs and reduces PCB area in microprocessor-bus systems like data acquisition and ATE

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX4617CPE+	8-channel, no on-chip latches; requires external address register; R_DS(on) = 60 Ω (typ), t_TRANS = 125 ns	Lacks integrated latches - increases component count and layout complexity in microprocessor-bus systems	Select when faster switching is prioritized over latch integration and board space savings
ADG408BNZ	8-channel, no latches; TTL-compatible but no RS/EN; R_DS(on) = 45 Ω (typ); charge injection = 25 pC	Higher charge injection degrades precision sampling; lacks reset and enable for stacked configurations	Prefer for simple, non-latched switching where low R_DS(on) outweighs latch convenience and low-injection needs

FAQ

What is the maximum analog signal voltage range supported by the DG428DJ-E3?

The DG428DJ-E3 supports a full analog signal range from V− to V+, with absolute maximum supply ratings of ±44 V. In standard dual-supply operation at ±15 V, it handles analog signals from –15 V to +15 V. In single-supply mode (e.g., V+ = 12 V, V− = 0 V), the range is 0 V to 12 V. This rail-to-rail capability eliminates external level-shifting for most sensor and actuator interfaces.

Does the DG428DJ-E3 require external latches for microprocessor interface?

No, the DG428DJ-E3 does not require external latches. It integrates on-chip TTL-compatible address latches for A0–A2 and EN inputs, allowing direct connection to microprocessor data/address buses. The WR strobe captures address states on its rising edge, and RS provides hardware reset - reducing external logic and PCB footprint in bus-controlled systems.

How does the break-before-make feature of the DG428DJ-E3 prevent crosstalk?

The DG428DJ-E3 guarantees a minimum break-before-make interval of 30 ns (t_OPEN) during channel transitions. This ensures that the previously selected channel is fully disconnected before the next channel closes, eliminating momentary conduction paths between adjacent analog inputs. This is critical in multi-signal systems like ATE or avionics where signal integrity and isolation must be preserved.

Can the DG428DJ-E3 operate from a single 5 V supply?

Yes, the DG428DJ-E3 supports single-supply operation down to 5 V (V+ = 5 V, V− = 0 V). However, its specified R_DS(on) increases to 150 Ω (max) and t_TRANS extends to 350 ns under these conditions. For optimal performance - especially in precision applications - dual ±15 V or single 12 V operation is recommended per the datasheet specifications.

What is the purpose of the RS (Reset) pin on the DG428DJ-E3?

The RS (Reset) pin on the DG428DJ-E3 is an active-high master reset that forces all internal address latches to zero and turns OFF all eight analog switches, regardless of the state of WR, EN, or address lines. This provides deterministic initialization at power-up or system fault recovery, and enables safe stacking of multiple DG428DJ-E3 devices in larger multiplexer arrays.
