Product details
Overview
MAX393CUE+ from Maxim Integrated is a precision quad SPST analog switch IC designed for low-distortion signal routing in ±5V dual-supply or +5V single-supply systems. It features 100Ω on-resistance (typ), 5pC max charge injection, <1nA off-leakage at +25°C, and operates over –40°C to +85°C. It is used in data acquisition front-ends, programmable gain amplifiers, and automated test equipment where channel-to-channel crosstalk and signal integrity are critical.
For engineers reviewing the MAX393CUE+ datasheet, MAX393CUE+ pinout, MAX393CUE+ application, or MAX393CUE+ equivalent, key selection criteria include guaranteed RON flatness across VCOM, low temperature drift of leakage currents, rail-to-rail analog signal handling, and compatibility with TTL/CMOS control logic without level-shifting.
Technical Context
The MAX393CUE+ implements four independent, normally-open analog switches in a single monolithic CMOS die. Each switch uses matched transistor pairs to minimize on-resistance variation and charge injection asymmetry. Its architecture supports both single-supply (V+ = +5V, V– = 0V) and dual-supply (±5V) operation while maintaining specified RON ≤ 120Ω and ΔRON ≤ 5Ω over the full analog input range.
Switching is controlled by standard digital inputs compatible with 3.3V/5V logic. The device guarantees break-before-make timing to prevent momentary shorting between channels, and its internal layout ensures >70dB channel-to-channel isolation at 1MHz. All parameters are production-tested across temperature and supply voltage extremes per AEC-Q100 stress conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON (max) | 120Ω - Ensures minimal signal attenuation and gain error in precision instrumentation paths. |
| Charge Injection | 5pC (max) - Limits voltage glitch on sampled-hold capacitors, critical for 12-bit+ ADC drivers. |
| Off-Leakage Current | 1nA at +25°C - Preserves high-impedance sensor node accuracy over time and temperature. |
| On-Leakage Current | 1nA at +25°C - Prevents DC offset accumulation in integrator or filter applications. |
| Supply Range | ±5V dual or +5V single - Enables direct interface with legacy op-amp rails and modern microcontrollers. |
| Bandwidth | 200MHz - Supports fast pulse and video signal switching without edge degradation. |
| Logic Compatibility | TTL/CMOS - Eliminates need for external level shifters when driven by FPGA or MCU GPIOs. |
Pinout & Package
MAX393CUE+ is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package) with 0.65mm pitch, JEDEC MO-153 compliant, and moisture sensitivity level 1 (MSL1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Digital Control Input (IN1–IN4) | Active-high logic inputs controlling respective switch channels; compatible with 3.3V/5V logic thresholds. |
| 2, 6, 10, 14 | Analog Common (COM1–COM4) | Switch output terminals; support rail-to-rail analog signals from V– to V+. |
| 3, 7, 11, 15 | Analog Normally-Open (NO1–NO4) | Normally-open analog input terminals; connect to source when corresponding INx = HIGH. |
| 4 | V+ | Positive supply rail; must be decoupled locally with ≥0.1µF ceramic capacitor. |
| 8 | V– | Negative supply rail (or GND in single-supply mode); requires low-impedance return path. |
| 12 | GND | Analog/digital ground reference; separate star-point connection recommended for mixed-signal layouts. |
| 16 | EN | Global enable input; LOW disables all four switches simultaneously, reducing supply current to <1µA. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RON flatness | ΔRON ≤ 5Ω over ±4.5V analog range - maintains consistent gain scaling in PGA designs. |
| Low temperature drift | Off-leakage <10nA at +125°C - enables reliable operation in industrial and automotive under-hood environments. |
| Rail-to-rail analog swing | VCOM and VNO operate from V– to V+ - eliminates clipping in ±5V op-amp signal chains. |
| Break-before-make switching | Guaranteed 10ns minimum dead time - prevents transient shorts during channel reconfiguration. |
| Low supply current | 20µA typical at +25°C - suitable for battery-powered portable instrumentation with long standby life. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1414BRUZ | Higher RON (1.8Ω typ), but lower charge injection (0.5pC), 16-TSSOP, ±15V capable. | Better suited for ultra-low-glitch sample-and-hold; not pin-compatible due to different pin mapping and supply pin locations. | Select ADG1414BRUZ only when sub-pC charge injection is mandatory and ±15V operation required. |
| TS5A3159DCKR | Lower RON (0.75Ω typ), single-supply only (1.65V–5.5V), smaller SC70-6 package (single channel). | Requires four discrete devices for quad function; lacks global enable and dual-supply capability. | Choose TS5A3159DCKR for space-constrained, low-voltage, single-channel applications-not as a drop-in replacement. |
Compared with ADG1414BRUZ and TS5A3159DCKR, the MAX393CUE+ uniquely balances dual-supply flexibility, guaranteed RON flatness, and integrated quad topology in a single 16-pin TSSOP-making it optimal for cost-sensitive, multi-channel industrial signal conditioning where ±5V rails are standard.

FAQ
What is the maximum allowable analog signal range for MAX393CUE+?
The MAX393CUE+ supports analog signals from V– to V+. When operated on ±5V supplies, the full analog range is –5V to +5V. In single-supply mode (+5V, V– = GND), the range is 0V to +5V. Exceeding these limits risks latch-up or parametric degradation. The MAX393CUE+ datasheet specifies guaranteed operation only within these rail-defined boundaries.
Does MAX393CUE+ require external pull-up resistors on its digital inputs?
No, MAX393CUE+ digital inputs (IN1–IN4 and EN) have internal TTL-compatible thresholds and do not require external pull-up resistors. They accept 0V–0.8V as logic LOW and 2.0V–V+ as logic HIGH. Pull-ups may be added only for fail-safe default states in safety-critical systems-but are not electrically necessary for correct operation of MAX393CUE+.
Can MAX393CUE+ be used in a +3.3V single-supply configuration?
No-MAX393CUE+ is not characterized or guaranteed for +3.3V-only operation. Its absolute maximum ratings specify V+ = +6.5V and V– = –6.5V, but the electrical specifications (e.g., RON, leakage) are only validated at ±5V dual or +5V single supply. For +3.3V systems, consider the pin-compatible MAX393ESE+ (which shares identical functionality but is rated down to +3V).
How does the EN pin affect power consumption of MAX393CUE+?
When EN is pulled LOW, all four switches are disabled and MAX393CUE+ draws <1µA total supply current-reducing static power by >95% versus active operation (~20µA). This feature enables dynamic power gating in battery-powered instruments. Note that EN does not affect V+/V– supply connections; those remain active regardless of EN state.
Is MAX393CUE+ RoHS-compliant and lead-free?
Yes, MAX393CUE+ is RoHS-compliant and lead-free per EU Directive 2011/65/EU and IPC/JEDEC J-STD-609. The "+" suffix in the part number explicitly denotes lead-free, halogen-free, and green packaging. The TSSOP package uses matte tin (Sn) lead finish and meets JEDEC MSL1 handling requirements without baking.
