Product details
Overview
MAX4547CPE from Analog Devices is a dual single-pole/double-throw (SPDT) CMOS T-switch optimized for bidirectional RF and video signal routing from DC to 300MHz in 50Ω/75Ω systems. It features 20Ω max on-resistance (±5V), -82dB off isolation at 10MHz, -84dB crosstalk, 1Ω max channel matching, and rail-to-rail analog signal handling - enabling high-fidelity video switching in broadcast equipment and RF test instrumentation.
For engineers reviewing the MAX4547CPE datasheet, MAX4547CPE pinout, MAX4547CPE application, or MAX4547CPE equivalent, this device is selected for low-distortion, high-bandwidth analog multiplexing where insertion loss flatness, off-state isolation, and TTL/CMOS logic compatibility under ±5V operation are critical design requirements.
Technical Context
The MAX4547CPE implements a true "T" switch topology with complementary N- and P-channel MOSFETs per path, ensuring symmetrical bidirectional conduction and minimal charge injection (60–150pC). Its internal logic-level translators accept 0.8V/2.4V thresholds and drive gate signals across full V+ to V− rails, enabling robust switching even with asymmetric supplies.
Each SPDT section operates with break-before-make timing (15–40ns typical), supports dual supplies (±2.7V to ±6V) or single +2.7V to +12V, and maintains <5nA COM_ off-leakage at +25°C. The CPE package uses 16-pin plastic DIP with isolated GND pins per switch to preserve high-frequency isolation and minimize ground bounce.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 300MHz - enables full HD video and RF signal routing without attenuation roll-off up to UHF. |
| On-Resistance (RON) | 20Ω max (±5V) - ensures ≤1dB insertion loss in 50Ω systems at 100MHz for minimal signal degradation. |
| Off Isolation | -82dB at 10MHz - suppresses leakage between active and inactive paths in multi-channel video routing. |
| Crosstalk | -84dB at 10MHz - prevents interference between adjacent SPDT channels in dense PCB layouts. |
| Signal-Path Matching | 1Ω max ΔRON - guarantees consistent gain/phase response across dual SPDT paths for balanced differential routing. |
| Supply Range | ±2.7V to ±6V dual or +2.7V to +12V single - supports legacy ±5V systems and modern low-voltage embedded designs. |
| Logic Compatibility | 0.8V/2.4V thresholds - interoperates directly with TTL and CMOS controllers without level-shifting circuitry. |
Pinout & Package
MAX4547CPE is housed in a 16-pin plastic DIP (Dual In-line Package) with through-hole mounting, rated for 0°C to +70°C operation. Pin assignments follow the standard MAX4547 functional layout with dedicated GND pins per switch section to maintain RF isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | IN1, IN2 | Digital control inputs - drive SPDT sections 1 and 2; accept 0.8V/2.4V logic thresholds. |
| 2, 16 | COM1, COM2 | Analog common terminals - bidirectional signal ports connected to NO/NC paths when enabled. |
| 4, 6, 12, 14 | NO1, NO2, NC1, NC2 | Normally open / normally closed analog terminals - define SPDT throw positions; interchangeable as input/output. |
| 3, 7, 10, 14 | GND1, GND2, GND3, GND4 | Isolated RF/logic grounds - must connect individually to ground plane to prevent coupling between switch sections. |
| 5, 13 | V−, V+ | Negative and positive supply pins - support bipolar (±5V) or single-supply (V− = GND) operation; require local 10nF bypassing. |
Key Features
| Feature | Design Value |
|---|---|
| T-switch architecture | Enables symmetrical bidirectional signal flow with flat on-resistance (0.5Ω max variation) over full analog range. |
| Rail-to-rail analog handling | Supports input signals from V− to V+ without clipping - essential for AC-coupled video and baseband RF waveforms. |
| Break-before-make timing | 15–40ns delay prevents momentary shorting during SPDT state transitions - avoids signal glitches in video sync paths. |
| ESD protection | >2kV per Method 3015.7 - safeguards against handling damage in manufacturing and field service environments. |
| Pin compatibility | Direct replacement for industry-standard DG540/DG542/DG643 - simplifies upgrade of legacy test and ATE equipment. |
Applications
| Video Signal Routing | RF Test Instrumentation |
|---|---|
|
Use Scenario: Switching between four SD/HD video sources to a single monitor or encoder in broadcast production switchers.

Use Scenario: Signal path configuration in automated RF test sets for cellular front-end validation (GSM, LTE, 5G NR bands). IC Role / Device Role / Timing Role: High-bandwidth RF switch enabling fast reconfiguration of stimulus/response paths without external attenuators or relays. Use Value: 300MHz -3dB bandwidth supports full coverage up to 3GHz harmonics with minimal phase distortion. |
| High-Speed Data Acquisition | ATE Equipment |
|
Use Scenario: Multiplexing multiple sensor outputs (e.g., thermocouples, strain gauges) into a shared 16-bit ADC in industrial DAQ modules. IC Role / Device Role / Timing Role: Low-leakage (≤5nA), low-RON analog switch minimizing offset error and settling time in precision measurement paths. Use Value: 1Ω max RON matching ensures channel-to-channel gain consistency within 0.05% across dual SPDT paths. |
Use Scenario: Signal routing matrix in semiconductor wafer probers and IC functional testers requiring nanosecond-scale path reconfiguration. IC Role / Device Role / Timing Role: Fast turn-on (90ns typ.) and turn-off (35ns typ.) SPDT switch enabling high-throughput parallel test sequences. Use Value: Break-before-make timing eliminates transient shorts during test vector changes, preventing DUT latch-up or damage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4547CPD | Same electrical specs; 16-pin wide SO package (surface-mount), no through-hole option. | Better high-frequency performance due to lower parasitic inductance; requires rework of PCB layout and assembly process. | Select CPD for new SMT designs prioritizing RF integrity and board space; retain CPE for through-hole prototyping or legacy repair. |
| ADG1419BRUZ | Single SPDT, 4.5Ω RON (±15V), -90dB isolation at 1MHz, but only 170MHz bandwidth and no pin compatibility. | Higher voltage rating suits industrial PLC I/O modules; insufficient bandwidth for >200MHz RF or HD video. | Choose ADG1419BRUZ only when ±15V operation or ultra-low RON is mandatory - not a drop-in replacement for MAX4547CPE. |
Compared with MAX4547CPD and ADG1419BRUZ, the MAX4547CPE uniquely balances through-hole manufacturability, 300MHz bandwidth, and proven -82dB isolation in cost-sensitive video/RF routing - making it optimal for field-replaceable modules and benchtop test gear where layout flexibility and legacy compatibility matter.

FAQ
What is the maximum operating frequency supported by the MAX4547CPE?
The MAX4547CPE delivers a -3dB signal bandwidth of 300MHz under ±5V supply conditions, verified per Figure 7 in the official datasheet. This allows full HD video (1080p60) and sub-3GHz RF harmonic routing without significant amplitude roll-off. Performance degrades above 300MHz due to increasing insertion loss and reduced off-isolation.
Can the MAX4547CPE operate from a single +5V supply?
Yes, the MAX4547CPE supports single-supply operation from +2.7V to +12V with V− tied to GND. However, at +5V single supply, on-resistance rises to 26–40Ω (vs. 14–20Ω at ±5V), switching speed slows (tON up to 250ns), and off-isolation drops to -75dB - so ±5V is strongly recommended for RF/video applications.
Does the MAX4547CPE support bidirectional analog signal flow?
Yes, the MAX4547CPE is fully bidirectional: COM, NO, and NC terminals are functionally identical and interchangeable per the datasheet (Note ** on page 8). Signals pass equally well in either direction, supporting flexible routing in both video multiplexers and RF transmit/receive path switching.
How many independent switches does the MAX4547CPE contain?
The MAX4547CPE contains two fully independent single-pole/double-throw (SPDT) analog switches. Each SPDT section has dedicated IN, COM, NO, and NC pins plus isolated GND connections - enabling simultaneous, uncoupled routing of two separate signal paths without crosstalk penalties.
What is the logic threshold voltage for the MAX4547CPE control inputs?
The MAX4547CPE IN1 and IN2 inputs have guaranteed logic thresholds of VIN_L ≤ 0.8V (max) and VIN_H ≥ 2.4V (min) when operated with ±5V supplies, ensuring direct compatibility with standard TTL and CMOS logic families without external level shifters or pull-ups.
