Product details
Overview
The MAX335ENG+ from Maxim Integrated is a serial-controlled, 8-channel SPST analog switch IC operating over ±4.5V to ±20V supplies, featuring 100Ω on-resistance, ±15V analog signal range, and SPI-compatible three-wire interface. It delivers rail-to-rail switching for precision signal routing in avionics and industrial process control systems.
For engineers reviewing the MAX335ENG+ datasheet, MAX335ENG+ pinout, MAX335ENG+ application, or MAX335ENG+ equivalent, key selection criteria include its -40°C to +85°C temperature rating, 24-pin narrow plastic DIP package, daisy-chainable serial interface, and guaranteed break-before-make timing of 15–25ns.
Technical Context
The MAX335ENG+ implements an 8-bit shift register synchronized to SCLK's rising edge, with CS-controlled latching on the rising edge only when SCLK is low. Its internal parallel register drives eight independent SPST switches, each bidirectional with constant on-resistance across the full ±15V analog range.
Digital I/O thresholds are VL-referenced (VIH = 2.4V at VL = +5V; VIL = 0.8V), supporting TTL-level logic compatibility. The DOUT output enables cascading up to multiple devices without external logic, while VL < 0.8V forces reset-clearing the shift register and turning all switches off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports rail-to-rail signal switching without clipping in bipolar systems |
| On-Resistance | 100Ω (typ) - ensures minimal voltage drop and signal distortion at 1mA load current |
| Switch Count & Type | 8 × SPST - enables independent control of eight discrete signal paths |
| Serial Interface | SPI-compatible three-wire (SCLK/DIN/CS) - integrates directly with microcontroller SPI peripherals |
| Turn-On/Off Time | 200–500ns / 90–500ns - enables high-speed multiplexing in data acquisition systems |
| Break-Before-Make Delay | 15–25ns - prevents momentary shorting during channel switching in critical analog paths |
| Operating Temperature | -40°C to +85°C - qualified for extended industrial and avionics environments |
Pinout & Package
MAX335ENG+ uses a 24-pin narrow plastic DIP package (0.300" width), with through-hole mounting and industry-standard pin spacing (0.100" row pitch). Pin 1 is SCLK; pins 5–20 carry NOx/COMx terminals in interleaved order; V+, V-, GND, VL, CS, DIN, SCLK, and DOUT occupy dedicated positions per the top-view layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SCLK | Serial clock input | Edge-triggered clock synchronizing DIN data into 8-bit shift register |
| 3 DIN | Serial data input | Accepts 8-bit control word; bit position determines individual switch state |
| 5–20 NO0–NO7, COM0–COM7 | Analog switch terminals | Bidirectional SPST contacts; NO/COM pairs form independent signal paths |
| 24 CS | Chip select | Latching control: rising edge updates switch states from shift register contents |
| 22 DOUT | Serial data output | Shift register Q7 output; enables daisy-chaining of multiple MAX335ENG+ devices |
| 23 VL | Logic supply/reset | +5V reference for digital inputs; pulsed below 0.8V resets shift register and disables all switches |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX336ENG+ | 16-channel SPST, same package and interface, but higher on-resistance (120Ω typ) and lower max supply (±16.5V) | Higher channel density at cost of analog performance margin | Select when needing >8 channels without board redesign; verify RON impact on signal accuracy |
| ADG508AKRZ-REEL7 | 8-channel CMOS MUX with parallel control (3-bit address), no serial interface, ±15V rating, 120Ω RON | Requires 3 address + 1 enable lines instead of 3-wire SPI; no daisy-chain support | Choose for simpler control architecture where GPIO availability exceeds serial bus constraints |
Compared with MAX335ENG+, MAX336ENG+ offers double the channel count in identical packaging but trades 20% higher on-resistance and reduced supply headroom; ADG508AKRZ-REEL7 provides equivalent channel count and voltage rating but requires parallel addressing and lacks serial scalability.

FAQ
What is the maximum supply voltage range supported by the MAX335ENG+?
The MAX335ENG+ operates with dual power supplies ranging from ±4.5V to ±20V. This allows rail-to-rail analog signal handling up to ±15V, making it suitable for high-dynamic-range industrial and avionics applications. Exceeding ±20V violates absolute maximum ratings and may cause permanent damage to the MAX335ENG+ device.
How does the serial interface of the MAX335ENG+ work with standard microcontrollers?
The MAX335ENG+ implements a three-wire SPI-compatible interface (SCLK, DIN, CS) that functions as an 8-bit shift register. Data is clocked in on the rising edge of SCLK while CS is low; the rising edge of CS latches the new switch configuration. This allows direct connection to standard MCU SPI peripherals configured for CPOL = 0, CPHA = 0, with no additional protocol translation needed for the MAX335ENG+.
Can multiple MAX335ENG+ devices be connected together, and if so, how?
Yes, multiple MAX335ENG+ devices can be daisy-chained using the DOUT pin. Connect DOUT of one MAX335ENG+ to DIN of the next, with all SCLK and CS lines tied in parallel. A single 8N-bit serial stream shifts through N devices; bringing CS high simultaneously updates all MAX335ENG+ switch states. This preserves pin count efficiency and simplifies firmware for multi-channel systems.
What happens to the MAX335ENG+ switches during power-up or reset?
Upon power-up, the internal shift register of the MAX335ENG+ resets to all zeros, leaving all eight SPST switches in the OFF state. Additionally, pulling VL below 0.8V triggers a hardware reset that clears the shift register and forces all switches OFF-providing deterministic startup behavior and fail-safe operation critical in safety-oriented systems using the MAX335ENG+.
Is the MAX335ENG+ suitable for use with single-supply systems?
Yes, the MAX335ENG+ supports single-supply operation by connecting V- to ground and setting VL = V+. In this configuration, the analog signal range becomes 0V to V+, with V+ ranging from +10V to +30V. However, VL cannot serve as a reset function in single-supply mode since VL is tied to V+, and the reset threshold (0.8V) would be violated. Designers must implement alternative reset logic for the MAX335ENG+ in such cases.
