Product details
Overview
DG2502DB-T2-GE1 from Vishay Siliconix is a quad SPST analog switch with normally open (NO) configuration, operating from 1.8 V to 5.5 V single supply. It delivers 200 Ω max on-resistance at 5 V, <1 nA max off-leakage at +85 °C, and 2.8 pF drain-off capacitance - optimized for low-distortion signal routing in portable medical and test equipment.
For engineers reviewing the DG2502DB-T2-GE1 datasheet, DG2502DB-T2-GE1 pinout, DG2502DB-T2-GE1 application, or DG2502DB-T2-GE1 equivalent, key selection criteria include rail-to-rail analog range, guaranteed break-before-make timing, WCSP16 package footprint compatibility, and leakage performance across -40 °C to +85 °C.
Technical Context
The DG2502DB-T2-GE1 implements four independent NO switches with matched RDS(on) (≤13 Ω max mismatch at room temperature) and TTL/CMOS-compatible control inputs (VINH = 1.8 V min at V+ = 5 V). Each channel supports bidirectional conduction and full rail-to-rail analog voltage swing (0 V to V+).
It guarantees break-before-make operation only in DG2503 - not applicable to DG2502DB-T2-GE1 - and features ESD/HBM tolerance >8 kV, latch-up immunity >800 mA (JESD78), and charge injection ≤–2 pC (at V+ = 5 V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUA+ | SO-16 package, 60 Ω RDS(on) max at 5 V, higher supply current (1 μA) | Requires PCB redesign due to larger footprint and different pinout; better for high-speed test fixtures | Select when lower on-resistance and SOIC assembly preference outweigh size constraints |
| ADG712BRUZ | 16-lead TSSOP, 4.5 Ω RDS(on) max at 5 V, 10 nA leakage at +85 °C | Higher leakage limits use in ultra-low-current medical monitoring; superior for general-purpose instrumentation | Choose for applications prioritizing on-resistance over leakage, where TSSOP layout is acceptable |
Compared with MAX4617EUA+ and ADG712BRUZ, DG2502DB-T2-GE1 offers the smallest footprint and lowest leakage, making it optimal for miniaturized, battery-sensitive healthcare devices - though its higher RDS(on) requires gain compensation in precision measurement paths.

FAQ
What is the maximum operating temperature range for DG2502DB-T2-GE1?
DG2502DB-T2-GE1 is specified for continuous operation from –40 °C to +85 °C. All electrical parameters - including leakage current, on-resistance, and switching times - are guaranteed across this full industrial temperature range, with leakage capped at 1 nA maximum at +85 °C.
Does DG2502DB-T2-GE1 support rail-to-rail analog signal switching?
Yes, DG2502DB-T2-GE1 supports rail-to-rail analog signal handling: its analog input range extends from GND to V+, allowing signals equal to the supply voltage to pass unattenuated when the switch is on. This eliminates the need for external level-shifting circuitry in most portable applications.
Is DG2502DB-T2-GE1 pin-compatible with DG2501DB-T2-GE1 or DG2503DB-T2-GE1?
No, DG2502DB-T2-GE1 is not pin-compatible with DG2501DB-T2-GE1 or DG2503DB-T2-GE1 in terms of functional behavior - though all three share identical WCSP16 pinout and package dimensions. DG2501 is normally closed, DG2502 is normally open, and DG2503 combines both; control logic and default states differ, requiring firmware and schematic review before substitution.
What is the guaranteed logic high threshold voltage for DG2502DB-T2-GE1 at 5 V supply?
At V+ = 5 V, DG2502DB-T2-GE1 guarantees a logic high input threshold (VINH) of ≥1.8 V and logic low (VINL) of ≤0.5 V. This ensures reliable interfacing with standard 5 V CMOS and TTL outputs without additional level translation.
Can DG2502DB-T2-GE1 be used in break-before-make configurations?
No - DG2502DB-T2-GE1 does not guarantee break-before-make operation. That feature is explicitly specified only for DG2503DB-T2-GE1 in the datasheet. DG2502DB-T2-GE1 is a simple NO switch; simultaneous switching of adjacent channels may cause momentary shorts if controlled improperly.
