Vishay Siliconix DG3000DB-T1-E1

Overview

DG3000DB-T1-E1 from Vishay Siliconix is a low-voltage single-pole/double-throw (SPDT) analog switch in MICRO FOOT® chip-scale package (1.07 × 1.57 mm, 6-bump), designed for high-performance signal routing in portable electronics. It delivers 1.4 Ω on-resistance at 5 V, 24 ns turn-on time, and operates from 1.8 V to 5.5 V supply - enabling compact, battery-efficient audio/data path switching in space-constrained handheld devices.

For engineers reviewing the DG3000DB-T1-E1 datasheet, DG3000DB-T1-E1 pinout, DG3000DB-T1-E1 application, or DG3000DB-T1-E1 equivalent, key selection criteria include guaranteed break-before-make timing, ultra-low charge injection (38 pC max at 5 V), RoHS-compliant Sn/Ag/Cu bump terminations, and compatibility with 0.5 mm pitch PCB land patterns per IPC/JEDEC J-STD-020A.

Technical Context

The DG3000DB-T1-E1 implements a monolithic CMOS SPDT switch built on Vishay's low-voltage JI2 process with epitaxial latchup prevention. Its control logic is TTL/CMOS-compatible, with input thresholds of 0.8 V (low) and 2.4 V (high) at V+ = 5 V, and it guarantees break-before-make operation to prevent signal shorting during state transitions.

Signal handling supports bidirectional conduction when on and blocks up to the power supply rail when off. Analog voltage range spans 0 to V+, with leakage currents as low as ±1.2 nA (ICOM(off)) at 5.5 V and 85 °C - critical for precision sensor multiplexing and low-power data acquisition paths.

FAQ

What is the maximum analog signal voltage supported by the DG3000DB-T1-E1?

The DG3000DB-T1-E1 supports analog signals from 0 V to V+, where V+ ranges from 1.8 V to 5.5 V. At V+ = 5.5 V, the absolute maximum analog voltage on NC, NO, or COM is (V+ + 0.3 V) = 5.8 V, per Absolute Maximum Ratings. Signals exceeding V+ are clamped by internal diodes, so design must limit forward diode current to ±50 mA continuous.

Does the DG3000DB-T1-E1 require external pull-up or pull-down resistors on its IN pin?

No, the DG3000DB-T1-E1 does not require external biasing on the IN pin. Its input structure is TTL/CMOS-compatible with guaranteed recognition of 0.8 V (max) for logic low and 2.4 V (min) for logic high at V+ = 5 V. Input current remains within ±1 µA across the full temperature range, eliminating need for external resistors in standard digital interface configurations.

Is the DG3000DB-T1-E1 still in production, and what is its lifecycle status?

Per Vishay documentation (Document Number 71742, Rev. F), the DG3000DB-T1-E1 is marked "Product is End of Life." However, Aetrix Electronics maintains active inventory and provides lifecycle coordination services including last-time buy planning, cross-reference support, and obsolescence mitigation for legacy designs dependent on DG3000DB-T1-E1.

How does the DG3000DB-T1-E1 handle latchup under overvoltage conditions?

The DG3000DB-T1-E1 is fabricated using Vishay Siliconix's low-voltage JI2 process with an epitaxial layer that prevents latchup. This design ensures immunity to destructive latchup even when analog signals exceed V+ (within Absolute Maximum Ratings), making DG3000DB-T1-E1 suitable for ruggedized portable applications where transient overvoltages may occur on signal lines.

Can the DG3000DB-T1-E1 be used in bidirectional signal paths such as I²C or UART lines?

Yes, the DG3000DB-T1-E1 supports fully bidirectional analog conduction when on - both NC→COM and COM→NC exhibit identical R_ON and dynamic characteristics. However, its 5 pF input capacitance and lack of bus-hold or slew-rate control make it unsuitable for high-speed digital buses like I²C or UART without careful signal integrity validation; it is optimized for analog signal routing, not digital protocol switching.
