Product details
Overview
DG2303DL-T1-E3 from Vishay Siliconix is a high-speed, low rON, single-pole single-throw (SPST) analog bus switch operating from 1.65 V to 5.5 V supply, featuring 7 Ω typical on-resistance at 4.5 V, <1 ns propagation delay, and TTL-compatible control inputs. It enables bidirectional signal routing between ports A and B under OE control in portable, low-voltage logic interface and data path isolation applications.
For engineers reviewing the DG2303DL-T1-E3 datasheet, DG2303DL-T1-E3 pinout, DG2303DL-T1-E3 application, or DG2303DL-T1-E3 equivalent, key selection criteria include supply voltage range (1.65–5.5 V), rON flatness (<6 Ω at 5 V), charge injection (0.5 pC), off-isolation (−50 dB at 10 MHz), and SC-70-5 package compatibility with space-constrained PCB layouts.
Technical Context
The DG2303DL-T1-E3 implements a CMOS transmission gate architecture with sub-micron process technology to achieve low on-resistance and minimal RC-dependent propagation delay. Its OE-controlled switch operates in flow-through mode with zero bounce and supports rail-to-rail analog/digital signal switching across 1.65–5.5 V V+.
It features internally clamped I/Os (−0.3 V to V+ + 0.3 V), 4 pF input capacitance, and 9 pF channel-off capacitance-enabling clean signal integrity in high-frequency data paths up to 200 MHz insertion loss bandwidth. Power supply current remains ≤1.0 µA across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V+ Supply Range | 1.65 V to 5.5 V - supports direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters |
| rON (Typ, 4.5 V) | 7.0 Ω - ensures minimal voltage drop and signal attenuation for 30 mA switched currents |
| tPHL/tPLH (Max, 4.5–5.5 V) | 1 ns - enables sub-nanosecond timing alignment in high-speed parallel bus and clock gating paths |
| Charge Injection | 0.5 pC - limits output voltage glitch during switching, critical for precision ADC/DAC multiplexing |
| Off-Isolation (10 MHz) | −50 dB - suppresses crosstalk between adjacent channels in multi-signal routing applications |
| IOFF Leakage (Max) | ±10 µA - maintains signal integrity in high-impedance sensor or reference paths |
| Input Capacitance | 4 pF - minimizes loading on driving sources in high-frequency digital or analog signal chains |
Pinout & Package
Package: SC-70-5 (SOT-353), 1.25 mm × 2.1 mm footprint, 0.65 mm pitch, RoHS-compliant Pb-free termination (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - V+ | Positive power supply | Bias rail for internal CMOS switch core; must be decoupled locally to minimize noise coupling |
| 2 - OE | Output enable control input | TTL-compatible active-low logic; drives switch ON when low, high-Z when high |
| 3 - A | Bidirectional analog/digital port | One end of transmission gate; connects to source or load depending on system topology |
| 4 - GND | Ground reference | Return path for V+, OE, and signal currents; requires low-inductance connection to minimize ground bounce |
| 5 - B | Bidirectional analog/digital port | Second end of transmission gate; electrically symmetric with A for true bidirectional operation |
Key Features
| Feature | Design Value |
|---|---|
| Low rON flatness | 6 Ω max variation over full 0–V+ signal swing at 5 V - preserves linearity in audio and sensor signal routing |
| Zero-bounce switching | No contact chatter or metastability during OE transitions - eliminates false triggering in synchronous data capture |
| Negligible propagation delay | 1 ns max tPHL/tPLH at 5 V - maintains timing budget in >500 Mbps parallel interfaces |
| Ultra-low ICC | 1.0 µA max supply current - extends battery life in always-on IoT sensor nodes and wearables |
| Rail-to-rail signal handling | Supports signals from GND to V+ without clipping - enables direct interfacing with ADC references and DAC outputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS5A23157DCUR | Lower rON (0.9 Ω typ at 3.3 V), but higher charge injection (12 pC); 6-pin SC70 package | Better for low-loss digital switching; less suitable for precision analog multiplexing due to higher glitch energy | Select TS5A23157DCUR only when ultra-low rON dominates over charge injection in high-speed digital paths |
| ADG701LBRJZ-REEL7 | Higher rON (3.5 Ω typ at 3 V), wider temp range (−40°C to 125°C), same SC-70-5 footprint | Preferred for extended-temperature industrial environments where DG2303DL-T1-E3's 85°C max ambient is insufficient | Choose ADG701LBRJZ-REEL7 when operating beyond 85°C ambient or requiring guaranteed automotive-grade reliability |
Compared with TS5A23157DCUR and ADG701LBRJZ-REEL7, the DG2303DL-T1-E3 delivers optimal balance of speed (1 ns delay), low glitch (0.5 pC), and wide supply range (1.65–5.5 V) in commercial-temperature, space-constrained designs-making it ideal for portable consumer electronics where size, power, and signal fidelity are co-prioritized.

FAQ
What is the maximum operating temperature for DG2303DL-T1-E3?
The DG2303DL-T1-E3 is rated for operation from −40 °C to +85 °C ambient temperature. Absolute maximum junction temperature is limited by power dissipation derating above 70 °C (3.1 mW/°C). Thermal design must ensure junction temperature remains within safe limits under worst-case V+, load current, and PCB copper area conditions. The DG2303DL-T1-E3 datasheet specifies full electrical performance across this industrial temperature range.
Does DG2303DL-T1-E3 support rail-to-rail analog signal switching?
Yes, the DG2303DL-T1-E3 supports rail-to-rail analog signal switching from GND to V+ (1.65 V to 5.5 V). Its CMOS transmission gate architecture allows signals spanning the full supply range without clipping or distortion, provided input voltages remain within the absolute maximum rating of −0.3 V to V+ + 0.3 V. This makes DG2303DL-T1-E3 suitable for interfacing with precision ADCs, DACs, and sensor outputs.
What is the typical on-resistance of DG2303DL-T1-E3 at 3.3 V supply?
At V+ = 3.3 V, the DG2303DL-T1-E3 exhibits a typical on-resistance of 9.0 Ω when VA = 0 V and IB = 24 mA, and 20.0 Ω when VA = 3.3 V and IB = 24 mA. The rON flatness is 12 Ω across the full signal swing, ensuring consistent performance in both low- and high-side signal routing configurations. These values are confirmed in the official Vishay DG2303 datasheet (Doc #72073, Rev. B).
Can DG2303DL-T1-E3 be used in bidirectional signal paths?
Yes, DG2303DL-T1-E3 is inherently bidirectional: ports A and B are electrically symmetric and interchangeable. Signal flow direction is determined solely by external circuit topology-not by internal design-so DG2303DL-T1-E3 functions identically whether driven from A to B or B to A. This symmetry is validated in the functional block diagram and truth table of the DG2303DL-T1-E3 datasheet.
Is DG2303DL-T1-E3 RoHS compliant and lead-free?
Yes, DG2303DL-T1-E3 is RoHS-compliant and lead-free, as indicated by the "E3" suffix in the part number and confirmed in the Vishay ordering information table. The device uses Pb-free terminations and meets exemption requirements under Directive 2011/65/EU. Full compliance documentation, including material declarations and test reports, is available via Vishay's PPAP portal using document number 72073.
