Product details
Overview
DG4157EDN-T1-GE4 from Vishay Siliconix is a single-pole, double-throw (SPDT) analog switch optimized for 1.65 V to 5.5 V single-supply operation, delivering 0.86 Ω on-resistance at 4.5 V, −64 dB off-isolation at 1 MHz, and 152 MHz −3 dB bandwidth - enabling high-fidelity signal routing in portable medical sensors and smartphone audio paths.
For engineers reviewing the DG4157EDN-T1-GE4 datasheet, DG4157EDN-T1-GE4 pinout, DG4157EDN-T1-GE4 application, or DG4157EDN-T1-GE4 equivalent, key selection criteria include powered-off isolation integrity, sub-1 Ω on-resistance stability across voltage/temperature, break-before-make timing control, and μDFN-6L footprint compatibility with space-constrained PCB layouts.
Technical Context
The DG4157EDN-T1-GE4 implements CMOS-based SPDT switching with guaranteed 1.8 V logic-high threshold up to 5.5 V supply, enabling direct interfacing with 1.8 V/3.3 V microcontrollers without level shifting. Its break-before-make architecture prevents signal shorting during state transitions, and integrated powered-off protection blocks current flow from COM to V+ when unpowered.
It supports bidirectional analog/digital signal transmission up to V+, exhibits low charge injection (−5 pC), and maintains <0.0055% THD+N over 20 Hz–20 kHz - critical for precision instrumentation front-ends and low-noise audio multiplexing where signal integrity must be preserved across rail-to-rail voltage swings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 0.86 Ω typical at V+ = 4.5 V, IO = 100 mA - ensures minimal insertion loss and voltage drop in signal path |
| Supply range | 1.65 V to 5.5 V single rail - supports direct integration with Li-ion battery-powered systems and mixed-voltage SoCs |
| Off-isolation | −64 dB at 1 MHz - suppresses crosstalk between inactive channels in multi-sensor data acquisition |
| Bandwidth | 152 MHz −3 dB - enables clean switching of high-speed video, USB 2.0, or RF test signals |
| Charge injection | −5 pC - minimizes glitch-induced offset in precision ADC input multiplexers and sample-hold circuits |
| Logic threshold | Guaranteed VINH ≥ 1.8 V across full supply range - ensures reliable activation from 1.8 V GPIOs without external biasing |
| ESD rating | 7 kV HBM - provides robust handling margin during automated assembly and field service in handheld devices |
Pinout & Package
Package: μDFN-6L (1.0 mm × 1.0 mm × 0.35 mm), ultra-compact leadless package with wettable flanks for automated optical inspection and high-density layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Control input | Active-high digital select line - connects B0 to A when low, B1 to A when high per truth table |
| 2 (A) | Common terminal | Bidirectional analog/digital I/O port - accepts signals up to V+ and routes to selected Bx output |
| 3 (B0) | Normally closed path | First SPDT throw - connected to A when S = 0; isolated when S = 1 |
| 4 (GND) | Ground reference | System ground return for internal logic and switch substrate - must be low-impedance for noise immunity |
| 5 (B1) | Normally open path | Second SPDT throw - connected to A when S = 1; isolated when S = 0 |
| 6 (V+) | Positive supply | Single power rail for analog and digital sections - powers internal CMOS switches and logic circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Powered-off isolation | Prevents backfeed current from COM to V+ during system power-down - eliminates risk of damaging downstream circuitry |
| Break-before-make switching | Guaranteed tBBM ≥ 1 ns - avoids momentary short-circuit between B0 and B1 during transition, protecting sensitive sources |
| Low on-resistance flatness | 0.05 Ω typical at V+ = 4.5 V - ensures consistent gain and linearity across full analog input voltage range (0–V+) |
| Ultra-low leakage | ±3 nA max switch-off current at full temperature range - preserves accuracy in high-impedance sensor interfaces |
| Logic-overvoltage tolerance | Control inputs accept up to 5.5 V regardless of V+ - allows direct connection to higher-voltage controllers without clamping diodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TS5A23157DCUR | 0.9 Ω on-resistance (typ), 1.65–5.5 V supply, but only 50 MHz bandwidth and no powered-off isolation circuit | Lacks powered-off protection - unsuitable where COM may be biased during V+ removal | Select when cost sensitivity outweighs need for fail-safe isolation and bandwidth >100 MHz |
| Analog Devices ADG849YRMZ-REEL7 | 0.5 Ω on-resistance (typ), 1.8–5.5 V supply, but requires minimum 1.8 V logic and offers no overvoltage-tolerant control inputs | No VINH guarantee below 1.8 V - incompatible with 1.65 V–1.8 V logic domains without level shifters | Select when ultra-low on-resistance is critical and system uses ≥1.8 V GPIOs with tight thermal constraints |
Compared with TS5A23157DCUR and ADG849YRMZ-REEL7, the DG4157EDN-T1-GE4 uniquely combines sub-1 Ω on-resistance, 152 MHz bandwidth, powered-off isolation, and 1.8 V logic threshold across its full 1.65–5.5 V supply range - making it optimal for battery-powered, safety-critical, or mixed-voltage signal routing where reliability and signal fidelity are non-negotiable.

FAQ
What is the maximum operating temperature range for the DG4157EDN-T1-GE4?
The DG4157EDN-T1-GE4 is specified for continuous operation from −40 °C to +85 °C ambient temperature, with a maximum junction temperature of 125 °C under normal bias conditions. This range is validated per JEDEC JESD22-A104 and supports deployment in automotive cabin modules, industrial edge sensors, and portable medical devices without derating.
Does the DG4157EDN-T1-GE4 support bidirectional signal flow?
Yes, the DG4157EDN-T1-GE4 supports fully bidirectional analog and digital signal transmission - signals up to V+ can pass from A to B0/B1 or from B0/B1 to A without polarity restriction. This capability is inherent to its CMOS transmission gate architecture and is confirmed in the functional description and truth table of the DG4157EDN-T1-GE4 datasheet.
What is the purpose of the powered-off isolation feature in the DG4157EDN-T1-GE4?
The powered-off isolation feature in the DG4157EDN-T1-GE4 prevents abnormal current flow from the COM (A) pin to V+ when the device is unpowered - a critical safeguard in systems where analog sensors remain biased while the host MCU or power rail is shut down. This function is implemented via an internal protection circuit and is explicitly verified in the Absolute Maximum Ratings and Applications sections of the DG4157EDN-T1-GE4 datasheet.
Can the DG4157EDN-T1-GE4 be used with a 1.65 V supply?
Yes, the DG4157EDN-T1-GE4 is fully operational at 1.65 V supply, with on-resistance characterized at 2.7 V and 4.5 V, and logic thresholds guaranteed down to the minimum supply. At 1.65 V, typical on-resistance rises to ~1.6 Ω (per DC Characteristics table), and switching times increase modestly - all parameters remain within specification across the full −40 °C to +85 °C range.
Is the DG4157EDN-T1-GE4 pin-compatible with the SC-70-6 variant DG4157EDL-T1-GE3?
No, the DG4157EDN-T1-GE4 (μDFN-6L) and DG4157EDL-T1-GE3 (SC-70-6) share identical electrical functionality and pin functions but differ in physical layout and solder pad geometry. The μDFN-6L uses a bottom-exposed thermal pad and 0.35 mm pitch, while SC-70-6 has gull-wing leads and 0.65 mm pitch - requiring separate PCB footprints and reflow profiles.
