Analog Devices Inc. SW060055S

Overview

SW060055S from Analog Devices is a quad SPST JFET analog switch monolithic silicon microcircuit designed for high-reliability military and aerospace signal routing. It operates with ±15 V dual supplies, delivers ≤110 Ω on-resistance across all switches, supports analog voltage range of ±10 V, and functions over -55°C to +125°C ambient temperature in GDIP1-T16 packaging.

For engineers reviewing the SW060055S datasheet, SW060055S pinout, SW060055S application, or SW060055S equivalent, this device is selected for precision analog multiplexing, fault-tolerant sensor interface, and MIL-STD-883-compliant signal switching where leakage <60 nA, isolation >50 dB, and sub-900 ns switching are required.

Technical Context

The SW060055S implements four independent JFET-based single-pole single-throw switches controlled by TTL/CMOS-compatible logic inputs and a global DISABLE terminal. Each channel exhibits matched on-resistance (≤20% R_ON match) and low off-capacitance (CD(OFF) ≤5.5 pF, CS(OFF) ≤7.0 pF), enabling minimal crosstalk (≥60 dB) and high-frequency signal integrity up to 500 kHz.

It features break-before-make timing (≥20 ns), guaranteed turn-on/off times (t_ON ≤900 ns, t_OFF ≤500 ns), and operates under MIL-PRF-38535 Class B non-JAN requirements with full screening per MIL-STD-883 methods including burn-in at +125°C and steady-state life testing for 1000 hours.

FAQ

What is the absolute maximum analog voltage range supported by SW060055S?

The SW060055S supports a continuous analog input voltage range of V− supply to V+ supply +20 V DC, which translates to -15 V to +35 V when operated at ±15 V supplies. This extended range allows safe handling of transient overvoltages beyond the supply rails without latch-up or damage, making SW060055S suitable for interfacing with sensors exhibiting overshoot or ringing behavior.

Does SW060055S require external pull-up or pull-down resistors on its logic inputs?

No, SW060055S does not require external pull-up or pull-down resistors on its logic inputs (IN1–IN4 or DISABLE). Its logic "0" input current (I_IL) is ≤10 µA and logic "1" input current (I_IH) is ≤10 µA across temperature, ensuring direct compatibility with standard TTL and CMOS outputs without additional biasing components. The internal input structure is designed for direct connection to digital controllers.

How is the DISABLE function implemented in SW060055S, and what happens to the switches when it is asserted?

In SW060055S, the DISABLE pin (Pin 13) is an active-low control that forces all four analog switches into the OFF state regardless of individual IN1–IN4 logic states. When DISABLE is pulled low (≤0.8 V), each channel's JFET is biased into cutoff, achieving ≤60 nA off-leakage and ≥50 dB isolation. This hardware-level override is essential for fail-safe signal isolation in safety-critical systems.

Is SW060055S available in non-hermetic packaging such as plastic DIP or SOIC?

No, SW060055S is only available in the hermetic GDIP1-T16 package per MIL-STD-1835 and the governing drawing 5962-89669. Analog Devices does not manufacture or qualify this part in plastic DIP or SOIC variants. Any non-hermetic version would not meet the MIL-PRF-38535 Class B requirements, burn-in, or 1000-hour life test specifications defined for SW060055S.

What is the thermal resistance (θ_JA) of SW060055S in its GDIP1-T16 package?

The junction-to-ambient thermal resistance (θ_JA) for SW060055S in the GDIP1-T16 package is 91°C/W maximum, as specified in Section 1.3 of the drawing. This value assumes standard PCB mounting conditions per MIL-STD-1835 and is used to calculate maximum allowable power dissipation (900 mW) under worst-case ambient temperatures up to +125°C without exceeding the +150°C maximum junction temperature rating.
