Product details
Overview
ADGS5414BCPZ-RL7 from Analog Devices is an octal SPST analog switch with SPI interface, designed for high-voltage multiplexer configurations in precision signal routing. It delivers 13.5 Ω typical on-resistance, ±20 V / +36 V dual/single-supply operation, break-before-make switching, and 8 kV HBM ESD rating - enabling robust relay replacement in automated test equipment and avionics data acquisition systems.
For engineers reviewing the ADGS5414BCPZ-RL7 datasheet, ADGS5414BCPZ-RL7 pinout, ADGS5414BCPZ-RL7 application, or ADGS5414BCPZ-RL7 equivalent, key selection criteria include guaranteed break-before-make timing (260 ns typ), CRC-enabled SPI error detection, trench-isolated analog section for latch-up immunity, and validated performance across −40°C to +125°C industrial temperature range.
Technical Context
The ADGS5414BCPZ-RL7 integrates eight independent SPST switches controlled via industry-standard SPI Mode 0/Mode 3 interface with daisy-chain and burst-mode support. Its digital core includes CRC, invalid address, and SCLK count error detection - critical for safety-critical systems requiring fault-aware configuration.
Analog section features trench isolation between positive/negative channel transistors, enabling operation up to ±22 V (dual) or +40 V (single) while blocking latch-up under overvoltage. Break-before-make action (260 ns typ) and flat on-resistance profile (1.8 Ω typ RFLAT(ON)) ensure low distortion in audio/video and instrumentation signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance (RON) | 13.5 Ω typ at ±20 V supply - ensures minimal signal attenuation and thermal drift in high-precision DC/low-frequency routing |
| Analog Signal Range | VSS to VDD - supports rail-to-rail input/output swing without clipping in ±20 V or +36 V single-supply configurations |
| Break-Before-Make Delay | 260 ns typ - guarantees no transient shorting during channel reconfiguration, enabling safe external wiring as a mux |
| SPI Clock Rate | Up to 50 MHz - reduces command latency in high-throughput ATE and real-time data acquisition |
| ESD Rating (HBM) | 8 kV - provides robust handling margin during board assembly and field maintenance in industrial environments |
| THD + N | 0.01% typ at 20 V p-p - maintains fidelity in audio and sensor signal switching applications |
| Supply Range | ±9 V to ±22 V dual or +9 V to +40 V single - accommodates legacy ±15 V, ±20 V, and high-voltage industrial rails |
Pinout & Package
The ADGS5414BCPZ-RL7 is housed in a 24-lead LFCSP package (CP-24-171) with exposed pad for thermal dissipation. Pin 1 is VDD; pins 2–17 are S1/D1 through S8/D8 bidirectional analog terminals; pins 18–24 serve digital control (VSS, SDO, RESET/VL, CS, SCLK, GND, SDI).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive supply rail | Accepts +9 V to +40 V (single) or +9 V to +22 V (dual); powers analog switch array and internal logic |
| S1–S8 (Pins 2,4,6,8,11,13,15,17) | Analog source terminals | Bidirectional inputs/outputs; each pairs with corresponding Dx pin to form independent SPST switch |
| D1–D8 (Pins 3,5,7,9,10,12,14,16) | Analog drain terminals | Bidirectional inputs/outputs; full VSS–VDD signal range supported with <1.4 Ω max RON match |
| VSS (Pin 18) | Negative supply rail | Accepts −9 V to −22 V (dual) or 0 V (single); must be tied to GND in unipolar operation |
| RESET/VL (Pin 20) | Logic power & hardware reset | 2.7 V–5.5 V logic supply; pulled low to reset registers and open all switches to default state |
| CS (Pin 21) | Active-low SPI frame sync | Enables shift register on falling edge; rising edge latches new switch states - enables precise timing control |
| SCLK (Pin 22) | SPI clock input | Supports up to 50 MHz; data captured on rising edge, SDO updated on falling edge per JEDEC timing |
| SDI/SDO (Pins 24/19) | SPI data in/out | SDI accepts 8-bit register writes; SDO is open-drain for daisy-chaining multiple ADGS5414 devices |
Key Features
| Feature | Design Value |
|---|---|
| SPI error detection suite | CRC, invalid address, and SCLK count validation - eliminates silent misconfiguration in safety-critical avionics and medical systems |
| Daisy-chain capability | Single CS/SCLK/SDI drives multiple ADGS5414BCPZ-RL7 units - reduces GPIO count and PCB routing complexity in multi-channel ATE |
| Trench-isolated analog core | Dielectric barrier between P/N channel transistors - prevents latch-up even during ±22 V overvoltage transients |
| Burst-mode SPI operation | Reduces inter-command delay by eliminating repeated CS assertion - accelerates sequential channel updates in real-time DAQ |
| Guaranteed break-before-make | 260 ns minimum tD - enables reliable external wiring of S/D pins into 1-of-8 multiplexer topologies without risk of short-circuits |

FAQ
What supply voltages does the ADGS5414BCPZ-RL7 support?
The ADGS5414BCPZ-RL7 operates from ±9 V to ±22 V dual supplies or +9 V to +40 V single supply. Valid configurations include ±15 V, ±20 V, +12 V, and +36 V rails - all fully characterized in the datasheet with specified RON, leakage, and timing. The device maintains 13.5 Ω typical on-resistance and guaranteed break-before-make timing across these ranges, making ADGS5414BCPZ-RL7 suitable for legacy and next-generation high-voltage systems.
Does the ADGS5414BCPZ-RL7 support daisy-chaining?
Yes, the ADGS5414BCPZ-RL7 supports daisy-chaining via its SDO (serial data out) pin, which is open-drain and requires an external pull-up to VL. Multiple ADGS5414BCPZ-RL7 devices can be cascaded using a single CS/SCLK/SDI bus, reducing digital I/O count and simplifying control of large switch matrices. Each device propagates data on the falling edge of SCLK, enabling synchronized configuration without additional logic.
What is the purpose of the RESET/VL pin on the ADGS5414BCPZ-RL7?
The RESET/VL pin serves dual functions: it supplies logic power (2.7 V–5.5 V) to the SPI interface and acts as a hardware reset input. Pulling RESET/VL low forces all eight switches to the open state and resets internal registers to default values - a critical feature for system recovery and deterministic startup. This eliminates reliance on software-only reset sequences, enhancing reliability in safety-critical ADGS5414BCPZ-RL7 deployments.
How does the ADGS5414BCPZ-RL7 prevent latch-up under overvoltage conditions?
The ADGS5414BCPZ-RL7 employs trench isolation technology: a dielectric barrier physically separates positive and negative channel transistors in the analog switch array. This structure blocks parasitic thyristor formation, preventing latch-up even when subjected to severe overvoltage transients beyond ±22 V. Combined with 8 kV HBM ESD rating, this makes ADGS5414BCPZ-RL7 uniquely suited for harsh environments like avionics and industrial test systems.
Can the ADGS5414BCPZ-RL7 be used as a multiplexer without external components?
No - the ADGS5414BCPZ-RL7 is an octal SPST switch, not a monolithic mux. However, its guaranteed break-before-make switching (260 ns min) allows safe external wiring of Sx/Dx pins to construct custom 1-of-8 or differential multiplexer configurations. This flexibility, combined with SPI control and error detection, gives designers full topology control while maintaining ADGS5414BCPZ-RL7's high-voltage and reliability advantages over integrated mux ICs.
