Product details
Overview
7705301XC from Maxim Integrated Products is a MIL-STD-883 compliant, non-JAN Class B quad SPST analog switch in a 16-pin flat pack (CDFP4-F16), rated for ±15 V analog signal range, 175 Ω max RDS(ON), and operation from –55°C to +125°C ambient. It serves as a precision signal routing device in military-grade data acquisition, test instrumentation, and avionics interface systems.
For engineers reviewing the 7705301XC datasheet, 7705301XC pinout, 7705301XC application, or 7705301XC equivalent, key selection criteria include guaranteed ±15 V analog signal swing, sub-1 µA off-state leakage at full temperature range, low 1000 ns typical switch ON time with 35 pF load, and compatibility with dual-rail ±15 V supply systems in harsh-environment embedded control.
Technical Context
This device implements four independent CMOS transmission gates with TTL-compatible digital control inputs, enabling bidirectional analog signal switching without polarity constraints. Its dielectric-isolation-free architecture (Device Type 01) ensures low charge injection (<10 pC) and minimal signal distortion across the full ±15 V range.
Designed for high-reliability analog multiplexing, it features rail-to-rail analog voltage handling (VS = V– –2 V to V+ +2 V), guaranteed 175 Ω maximum on-resistance at ±10 V, and <±2 nA off-leakage over –55°C to +125°C - critical for precision sensor front-ends and calibration paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog signal range | ±15 V - supports full-scale bipolar signals without clipping in data acquisition channels |
| RDS(ON) max | 175 Ω - ensures ≤0.1% gain error in 10 kΩ source/load impedance applications |
| Off leakage (IS(OFF)) | ±2 nA - maintains >100 MΩ effective channel isolation at extreme temperatures |
| Switch ON time | 1000 ns - enables 1 MSPS multiplexed sampling with 35 pF capacitive load |
| Supply voltage range | ±15 V DC - compatible with standard military power rails and legacy test equipment |
| Operating temp range | –55°C to +125°C - qualified for airborne, ground vehicle, and space-qualified subsystems |
| Power dissipation | 750 mW - allows continuous operation at full rating up to +75°C ambient (derated above) |
Pinout & Package
7705301XC is packaged in a hermetic 16-pin flat pack (CDFP4-F16), outline letter X per MIL-STD-1835, with gold-plated leads and glass-sealed ceramic body for moisture resistance and long-term reliability in sealed enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 16 | IN1–IN4 | Digital control inputs - TTL-compatible (VIL ≤ 0.8 V, VIH ≥ 2.4 V); active-high enable |
| 2, 5, 10, 15 | D1–D4 | Drain terminals - bidirectional analog signal path; connected to load side of switch |
| 3, 6, 11, 14 | S1–S4 | Source terminals - bidirectional analog signal path; connected to source/sensor side |
| 7 | GND | Signal reference ground - separate from power return; minimizes ground bounce in mixed-signal layouts |
| 8 | V– | Negative supply rail - must be connected to –15 V for full ±15 V analog range compliance |
| 12 | V+ | Positive supply rail - must be connected to +15 V for full ±15 V analog range compliance |
| 13 | NC | No connect - internally unconnected; must remain floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports signals from V– –2 V to V+ +2 V - eliminates level-shifting circuitry in ±15 V systems |

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 |
|---|---|---|---|
| DG201AAZ/883 | Same DG201A core, but in CDIP2-T16 (case E); higher θJA, lower power derating slope (12 mW/°C vs. 10 mW/°C) | Better suited for lab-bench prototypes with through-hole assembly; less optimal for high-density surface-mount avionics PCBs | Select when board-level rework or socket-based validation is required; avoid for hermetic, high-vibration deployments |
| HI4-201/883 | Dielectric-isolated variant (Device Type 02); wider digital input range (VIN = V– –4 V to V+ +4 V), but higher RDS(ON) (70 Ω min, 100 Ω max) | Preferred for systems requiring enhanced latch-up immunity in radiation-prone or high-noise industrial settings | Choose only when dielectric isolation is mandated by system safety analysis; otherwise 7705301XC offers superior on-resistance and cost efficiency |
Compared with DG201AAZ/883 and HI4-201/883, the 7705301XC delivers optimal balance of low on-resistance (175 Ω), hermetic flat-pack reliability, and direct compatibility with standard ±15 V military power architectures - making it the preferred choice for volume-deployed avionics and test instrumentation where signal fidelity and long-term stability are paramount.

FAQ
What is the absolute maximum analog signal voltage range supported by the 7705301XC?
The 7705301XC supports an absolute maximum analog signal range of V– –2 V to V+ +2 V. With recommended operating conditions of V+ = +15 V and V– = –15 V, this yields a guaranteed ±15 V signal-handling capability. This specification is verified per MIL-STD-883 test method 3015 and applies across the full –55°C to +125°C ambient temperature range. Exceeding these limits risks permanent damage to the internal CMOS transmission gates.
Does the 7705301XC require external pull-up or pull-down resistors on its digital control inputs?
No, the 7705301XC does not require external pull-up or pull-down resistors on its IN1–IN4 pins. Its TTL-compatible inputs have defined thresholds: VIL ≤ 0.8 V (max) and VIH ≥ 2.4 V (min), with input leakage current limited to ±1 µA at VIN = 0 V. When driven directly by standard 5 V logic or microcontroller GPIOs, the 7705301XC operates reliably without external biasing - confirmed in Group A subgroup 1 testing per Table I of the drawing.
What is the maximum continuous current rating per switch channel (S/D terminal) for the 7705301XC?
The 7705301XC has a maximum continuous current rating of 20 mA per switch channel (source or drain terminal), as specified in section 1.3 of the drawing. This limit applies under recommended operating conditions (V+ = +15 V, V– = –15 V, TA ≤ +125°C) and is validated via steady-state life testing per MIL-STD-883 method 1005. Peak pulsed current (1 ms, 10% duty cycle) is rated at 70 mA - sufficient for transient sensor excitation or calibration pulses.
Is the 7705301XC pin-compatible with commercial-grade DG201A variants like the DG201ACJ?
No, the 7705301XC is not pin-compatible with commercial DG201A variants such as the DG201ACJ. While both share the same functional topology and basic pin numbering (IN/D/S/GND/V+/V–), the 7705301XC uses the CDFP4-F16 flat pack (outline X) with gull-wing leads, whereas the DG201ACJ uses a 16-pin SOIC package. Physical dimensions, lead pitch, and solder footprint differ significantly - requiring distinct PCB layouts. Electrical behavior is aligned, but mechanical integration is not interchangeable.
How is the 7705301XC screened for long-term reliability in military applications?
The 7705301XC undergoes full MIL-STD-883 Class B screening per method 5004, including burn-in at +125°C minimum, interim and final electrical testing across subgroups 1, 2, 3, 9, 10, and 11, and 1000-hour steady-state life testing per method 1005. These tests verify parametric stability, interconnect integrity, and die-level robustness under thermal stress - all documented in the certificate of conformance provided with each lot. This qualifies the 7705301XC for use in mission-critical defense platforms with >10-year field service life.
