Product details
Overview
DG2503DB-T2-GE1 from Vishay Siliconix is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, operating from 1.8 V to 5.5 V single supply. It delivers 200 Ω max RDS(on) at 3 V, <1 nA leakage at +85 °C, and guaranteed break-before-make timing-ideal for precision sample-and-hold and portable medical sensor signal routing.
For engineers reviewing the DG2503DB-T2-GE1 datasheet, DG2503DB-T2-GE1 pinout, DG2503DB-T2-GE1 application, or DG2503DB-T2-GE1 equivalent, key selection criteria include its WCSP16 package footprint, rail-to-rail analog voltage handling (0 V to V+), dual NO/NC channel configuration, and low 2.7 pF CD(off) for high-frequency signal integrity in battery-powered instrumentation.
Technical Context
The DG2503DB-T2-GE1 integrates four independent analog switches on a monolithic silicon die, each with matched on-resistance (ΔRon ≤13 Ω over temperature) and guaranteed break-before-make operation-critical for multiplexer-based signal path switching without transient shorts. Its control logic accepts TTL/CMOS inputs with VINH = 1.4 V (at V+ = 3 V) and VINL = 0.4 V, enabling direct interfacing with low-voltage microcontrollers.
Designed for full-rail analog signal handling, it supports bidirectional conduction with analog voltage range spanning GND to V+, while maintaining low charge injection (–2 pC typical at 5 V) and off-isolation of –84 dB at 1 MHz-enabling accurate low-distortion sampling in healthcare front ends and automatic test equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) max | 200 Ω at 3 V supply - ensures minimal signal attenuation in low-power sensor interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUB+ | SO-10 package; higher RDS(on) (350 Ω max); no guaranteed break-before-make | Less suitable for medical multiplexing due to lack of BBM assurance and larger footprint | Select when board space allows SOIC and BBM is not safety-critical |
| ADG712BRUZ | 16-lead TSSOP; 4.5 Ω typical RDS(on); 5 V only; no NC/NO mix | Requires external logic for dual-mode behavior; incompatible with 1.8 V microcontrollers | Prefer for high-precision, fixed-configuration 5 V systems where ultra-low Ron dominates |
Compared with MAX4617EUB+ and ADG712BRUZ, DG2503DB-T2-GE1 uniquely combines WCSP16 miniaturization, dual NO/NC topology, guaranteed BBM, and 1.8 V compatibility - making it the only option meeting all four requirements for next-gen portable medical sensor hubs.

FAQ
What is the maximum allowable supply voltage for DG2503DB-T2-GE1?
The absolute maximum supply voltage (V+) for DG2503DB-T2-GE1 is +6 V referenced to GND. However, the device is fully specified and characterized for reliable operation from 1.8 V to 5.5 V. Operation above 5.5 V may cause permanent damage and is not recommended, even for transient conditions. The 6 V rating is a stress limit only, not an operational specification.
Does DG2503DB-T2-GE1 support rail-to-rail analog signal switching?
Yes, DG2503DB-T2-GE1 supports true rail-to-rail analog signal handling: its analog input range extends from GND to V+, with full functionality across the entire supply range. This is confirmed in the Electrical Characteristics tables for both 3 V and 5 V supplies, where VANALOG is specified as 0 to V+ under all operating temperatures.
How many of the four switches in DG2503DB-T2-GE1 are normally open versus normally closed?
DG2503DB-T2-GE1 contains two normally open (NO) switches and two normally closed (NC) switches. This configuration is explicitly defined in the Ordering Information table and Truth Table section of the datasheet, distinguishing it from DG2501 (quad NC) and DG2502 (quad NO).
Is DG2503DB-T2-GE1 pin-compatible with DG2501DB-T2-GE1 or DG2502DB-T2-GE1?
Yes, DG2503DB-T2-GE1 shares identical WCSP16 pinout, package dimensions, and bump layout with DG2501DB-T2-GE1 and DG2502DB-T2-GE1. All three variants use the same mechanical footprint and electrical pin assignments-only the internal switch configuration (NO/NC mapping) differs. No PCB redesign is required when substituting within this family.
What is the guaranteed break-before-make time for DG2503DB-T2-GE1?
The guaranteed minimum break-before-make (BBM) time for DG2503DB-T2-GE1 is 10 ns over the full operating temperature range (–40 °C to +85 °C), as specified in the Electrical Characteristics tables for both 3 V and 5 V supplies. This parameter applies specifically to the DG2503 variant and is not guaranteed for DG2501 or DG2502.
