Product details
Overview
MAX3295AUT+TCGK from Maxim Integrated is a high-speed, low-power RS-485/RS-422 differential transmitter IC operating from a single +3.3V supply, delivering 20Mbps data rate, <5ns output skew, and guaranteed propagation delay <25ns. It features hot-swap input protection, ±9kV HBM ESD rating on Y/Z pins, and automotive-grade operation from –40°C to +125°C - deployed in industrial control networks and automotive infotainment backbones.
For engineers reviewing the MAX3295AUT+TCGK datasheet, MAX3295AUT+TCGK pinout, MAX3295AUT+TCGK application, or MAX3295AUT+TCGK equivalent, key selection criteria include its 20Mbps capability without slew-rate limiting, 1µA shutdown current, SOT23-6 package footprint, and AEC-Q100-compliant performance under automotive thermal stress.
Technical Context
The MAX3295AUT+TCGK implements a BiCMOS driver stage with active-high DE enable logic and true differential Y/Z outputs compliant with RS-485/RS-422 voltage levels (≥±1.5V into 54Ω). Its hot-swap circuitry includes a 10µs internal pulldown timer on DE during VCC ramp-up to prevent false enables during live insertion.
Driver protection integrates dual-stage fault response: foldback current limiting across –7V to +12V common-mode range and thermal shutdown at +160°C with 40°C hysteresis. Unlike the slew-rate-limited MAX3293/MAX3294 variants, the MAX3295AUT+TCGK maintains fast edge rates for high-fidelity signal integrity at 20Mbps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 20Mbps - supports high-throughput serial links in real-time industrial automation and automotive diagnostics. |
| Supply Voltage | +3.3V ±5% - compatible with standard low-voltage digital logic rails; requires 0.1µF local bypass at VCC. |
| Output Skew | <5ns - ensures tight timing alignment between Y and Z outputs, critical for jitter-sensitive clock distribution. | Propagation Delay | <25ns - guarantees sub-25ns signal path latency from DI/DE assertion to valid Y/Z transition. |
| Shutdown Current | 1µA - enables ultra-low-power sleep states in battery-backed or energy-conscious systems. |
| Common-Mode Range | –7V to +12V - tolerates ground potential differences and noise transients in long-haul RS-485 bus topologies. |
| ESD Rating | ±9kV HBM - protects Y/Z bus pins against electrostatic discharge during handling and field deployment. |
Pinout & Package
MAX3295AUT+TCGK is housed in a RoHS-compliant 6-pin SOT23-6 package (package code U6CN+2), with 1.3mm pitch, 2.9mm × 1.6mm footprint, and thermal resistance θJA = 122.3°C/W (single-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - DI | Single-ended logic input | Drives differential output polarity: DI = HIGH → Y=HIGH/Z=LOW; DI = LOW → Y=LOW/Z=HIGH. |
| 2 - VCC | Positive supply rail | +3.3V ±5% input; must be decoupled to GND with 0.1µF ceramic capacitor near pin. |
| 3 - DE | Active-high driver enable | Hot-swap tolerant; internal 10µs pulldown prevents false enable during power-up; high-impedance when disabled. |
| 4 - Z | Inverting RS-485/RS-422 output | Differential complement to Y; forms 1.5V minimum VOD across 54Ω load per RS-485 spec. |
| 5 - GND | Signal reference ground | Return path for VCC and logic inputs; must be connected to system ground plane with low-inductance trace. |
| 6 - Y | Noninverting RS-485/RS-422 output | Differential complement to Z; pair forms robust noise-rejecting transmission line interface. |
Key Features
| Feature | Design Value |
|---|---|
| 20Mbps High-Speed Operation | Enables real-time sensor telemetry and control loop updates in automotive ADAS and factory robotics without slew-rate trade-offs. |
| Hot-Swap Input Protection | Internal 10µs DE pulldown eliminates data corruption during live insertion into powered backplanes or modular chassis. |
| Thermal Shutdown + Foldback Limiting | Prevents latch-up or damage during bus contention or short-circuit faults by forcing Y/Z into high-Z state at +160°C or >±250mA output. |
| AEC-Q100 Qualified | Validated for automotive applications including engine control modules and body electronics requiring –40°C to +125°C reliability. |
| ±9kV HBM ESD on Bus Pins | Eliminates need for external TVS diodes on Y/Z lines in harsh environments like vehicle service bays or industrial floors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RS-485/RS-422 transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3295AUT/V+T | Identical electrical specs and pinout; carries explicit AEC-Q100 qualification mark (+ACSB top mark) and automotive traceability. | Required for OEM automotive production where full AEC-Q100 documentation and lot traceability are mandated. | Select MAX3295AUT/V+T when formal automotive qualification evidence (test reports, PPAP) is contractually required. |
| THVD1550DR | 20Mbps, +3.3V, 1µA shutdown, but only ±12kV IEC 61000-4-2 ESD (not HBM); no hot-swap DE circuitry. | Suitable for industrial IoT gateways where ESD robustness targets system-level surge standards, not component-level HBM. | Choose THVD1550DR if IEC-level ESD compliance and cost sensitivity outweigh hot-swap and HBM requirements. |
Compared with MAX3295AUT+TCGK, MAX3295AUT/V+T offers identical performance with certified automotive pedigree, while THVD1550DR trades hot-swap and HBM ESD for higher IEC surge immunity and lower unit cost - making each optimal for distinct compliance-driven design contexts.

FAQ
What is the maximum data rate supported by the MAX3295AUT+TCGK?
The MAX3295AUT+TCGK supports a maximum data rate of 20Mbps, verified under RDIFF = 54Ω and CL = 50pF conditions at temperatures up to +85°C. This performance is enabled by its non-slew-rate-limited architecture, distinguishing it from the slower MAX3293 (250kbps) and MAX3294 (2.5Mbps) variants in the same family. The MAX3295AUT+TCGK maintains this speed across its full automotive temperature range (–40°C to +125°C) with typical rise/fall times of 15ns.
Does the MAX3295AUT+TCGK include hot-swap protection on the DE pin?
Yes, the MAX3295AUT+TCGK integrates dedicated hot-swap circuitry on the DE pin. During VCC ramp-up, an internal 10µs timer activates a pulldown network that holds DE low, preventing false driver enables caused by floating inputs or parasitic coupling. After initialization, DE transitions to a standard CMOS input with ±2µA leakage. This feature is explicitly documented in the Hot-Swap Input Circuitry section of the MAX3295AUT+TCGK datasheet and applies identically across all MAX3293–MAX3295 variants.
What is the shutdown current consumption of the MAX3295AUT+TCGK?
The MAX3295AUT+TCGK draws a maximum of 10µA in shutdown mode when DE is pulled low, with typical consumption at 1µA under no-load conditions. This specification is guaranteed over the full automotive temperature range (–40°C to +125°C) and is measured with VCC = +3.3V and DI at either rail. The low shutdown current enables energy-efficient sleep modes in battery-powered remote sensors and portable diagnostic tools using the MAX3295AUT+TCGK.
Is the MAX3295AUT+TCGK AEC-Q100 qualified?
The MAX3295AUT+TCGK is automotive-grade and specified over –40°C to +125°C, but AEC-Q100 qualification is formally assigned to the MAX3295AUT/V+T variant (top mark +ACSB). While both share identical electrical characteristics and packaging, only MAX3295AUT/V+T carries the documented AEC-Q100 test report and traceability required for Tier 1 automotive production. The MAX3295AUT+TCGK remains suitable for non-OEM automotive subsystems where full qualification is not mandated.
What package type and pin count does the MAX3295AUT+TCGK use?
The MAX3295AUT+TCGK uses a 6-pin SOT23-6 package (outline number 21-0058, land pattern 90-0175), with pin 1 = DI, pin 2 = VCC, pin 3 = DE, pin 4 = Z, pin 5 = GND, and pin 6 = Y. This RoHS-compliant package measures 2.9mm × 1.6mm with 1.3mm lead pitch and supports reflow soldering at +260°C. Its compact size enables dense PCB layouts in space-constrained modules such as automotive camera ECUs and handheld test equipment using the MAX3295AUT+TCGK.
