Product details
Overview
DG2302DL-T1-E3 from Vishay Siliconix is a high-speed, single-pole single-throw (SPST) analog bus switch with TTL-compatible control, 5 Ω on-resistance at 4.5 V, sub-1 ns propagation delay, and SC-70-5 packaging-used for level-shifting and signal routing in low-voltage digital interfaces.
For engineers reviewing the DG2302DL-T1-E3 datasheet, DG2302DL-T1-E3 pinout, DG2302DL-T1-E3 application, or DG2302DL-T1-E3 equivalent, this device serves as a bi-directional, low-rON, flow-through bus switch enabling fast signal pass-through between A and B ports under OE control in space-constrained logic interface designs.
Technical Context
The DG2302DL-T1-E3 implements a CMOS-based transmission gate architecture with rail-to-rail analog signal handling capability up to V+ = 5.5 V. Its OE-controlled switch operates in flow-through mode with zero bounce and supports bidirectional signal transfer between pins A and B without directionality constraints.
It features TTL-level compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), low dynamic power consumption (I+ ≤ 1.5 mA active, ≤1.0 µA disabled), and minimal capacitive loading (CON = 11 pF, COFF = 5 pF), making it suitable for high-speed digital bus isolation and voltage-level translation between mixed-supply domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance (rON) | 7 Ω max at V+ = 4.5 V, VA = 0 V, IB = 64 mA - ensures minimal voltage drop and signal distortion in 3.3 V/5 V logic paths. |
| Propagation Delay (tPHL/tPLH) | 1 ns max - enables reliable operation in >500 MHz data rate applications with tight timing budgets. |
| Supply Voltage Range (V+) | 4.0 V to 5.5 V - compatible with standard 5 V and 3.3 V system rails when used with level-shifting biasing. |
| Input Logic Compatibility | TTL-level (VIH ≥ 2.0 V, VIL ≤ 0.8 V) - directly interfaces with legacy 5 V TTL and modern 3.3 V CMOS controllers without external level shifters. |
| Channel Capacitance | CON = 11 pF, COFF = 5 pF - reduces signal integrity degradation and crosstalk in high-frequency bus switching. |
| Leakage Current (Ioff) | ±10 µA max at V+ = 5.5 V - maintains signal integrity during off-state in battery-powered or low-power standby modes. |
Pinout & Package
SC-70-5 surface-mount package (2.0 mm × 1.25 mm × 0.95 mm height), moisture sensitivity level 1 (MSL-1), Pb-free and RoHS-compliant per Vishay specification S-70852–Rev. B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - V+ | Positive supply rail | Provides operating power; must be decoupled locally to minimize noise coupling into analog path. |
| 2 - OE | Output enable control input | Active-low logic input; drives internal switch ON when low, places A–B path in high-Z when high. |
| 3 - A | Bi-directional analog/digital port | One end of the switched path; accepts signals up to V+ and tolerates clamping diodes to V+ and GND. |
| 4 - GND | Ground reference | Return path for supply and signal currents; must be connected to system ground plane with low-inductance trace. |
| 5 - B | Bi-directional analog/digital port | Other end of the switched path; functionally identical to pin A; supports full bidirectional signal flow. |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance | 7 Ω max ensures <50 mV drop at 64 mA, preserving logic high/low margins in 3.3 V systems. |
| Sub-1 ns propagation delay | Enables use in high-speed parallel buses (e.g., address/data latching) without adding timing skew. |
| Zero-bounce switching | Eliminates contact chatter artifacts in flow-through mode-critical for glitch-free clock or strobe routing. |
| TTL-compatible control inputs | Accepts standard 5 V TTL outputs directly, removing need for external level translators in mixed-voltage systems. |
| Bi-directional signal path | Supports A→B or B→A signal flow without polarity or direction configuration-simplifies PCB layout and firmware. |
Applications
| PCI Express Signal Routing | USB 2.0 Data Line Switching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS5A23157DGSR | 0.9 Ω rON at 3.3 V, but rated only to 3.6 V V+; higher CON (17 pF); supports 1.65–3.6 V operation. | Better for ultra-low-voltage (1.8 V) systems; unsuitable for 5 V-tolerant designs requiring V+ = 5.5 V operation. | Select TS5A23157DGSR only when supply is strictly ≤3.6 V and sub-1 Ω rON is required; DG2302DL-T1-E3 remains preferred for 5 V compatibility. |
| SN74CBT3244PWR | 8-bit bus switch, 7 Ω rON, same SC-70-5 pinout not available-requires TSSOP-20; higher ICC (3 mA active). | Used where multi-bit parallel switching is needed; not a drop-in replacement due to different channel count and package. | Choose SN74CBT3244PWR for 8-bit wide bus isolation; DG2302DL-T1-E3 is optimal for single-line, space-constrained, low-power point-to-point routing. |
Compared with TS5A23157DGSR and SN74CBT3244PWR, the DG2302DL-T1-E3 uniquely balances 5 V tolerance, SC-70-5 footprint, sub-1 ns speed, and ±10 µA off-leakage-making it the most suitable choice for compact, mixed-voltage, high-speed signal routing where single-channel performance and voltage margin are critical.

FAQ
What is the maximum supply voltage rating for DG2302DL-T1-E3?
The DG2302DL-T1-E3 has an absolute maximum V+ rating of +6.0 V, with recommended operating range from 4.0 V to 5.5 V. Operation beyond 5.5 V risks exceeding safe junction temperature and may trigger internal clamp diode conduction, potentially degrading long-term reliability. The DG2302DL-T1-E3 is optimized for stable performance at 5.0 V nominal supply.
Does DG2302DL-T1-E3 support bidirectional signal flow between pins A and B?
Yes, the DG2302DL-T1-E3 provides fully bidirectional signal conduction between pins A and B when OE is asserted low. There is no intrinsic directionality-the device functions identically regardless of signal source location. This makes the DG2302DL-T1-E3 ideal for applications like USB data line switching or shared ADC input routing where signal direction changes dynamically.
What is the typical on-resistance value of DG2302DL-T1-E3 at 3.3 V supply?
The DG2302DL-T1-E3 is not characterized or guaranteed for operation below 4.0 V V+, and no rON specification is provided at 3.3 V in the official Vishay datasheet (Document Number: 72072, Rev. B). Its specified rON of 7 Ω max applies at V+ = 4.5 V. For 3.3 V systems, consider alternatives explicitly rated down to 1.65 V, such as the TS5A23157.
Is DG2302DL-T1-E3 pin-compatible with other SC-70-5 analog switches?
No documented pin-compatible replacements exist for the DG2302DL-T1-E3 within the SC-70-5 package. While pin count and outline match common 5-lead SC-70 devices, the specific assignment (V+, OE, A, GND, B) differs from industry-standard layouts like the TS5A23157 (which uses V+, GND, IN, EN, OUT). Layout reuse requires verification of both pin mapping and electrical behavior-not just package dimensions.
How does DG2302DL-T1-E3 handle input signals exceeding V+?
The DG2302DL-T1-E3 includes internal ESD protection diodes that clamp signals on pins A, B, or OE to V+ and GND. If a signal exceeds V+ by more than 0.3 V, forward conduction occurs through the V+-clamp diode. Per datasheet Note a, forward diode current must be limited to rated maximums (±50 mA continuous) using external series resistance to prevent latch-up or thermal damage to the DG2302DL-T1-E3.
