MAX3095CEE+ 概述
A receiver IC is a physical-layer interface device that converts differential signalling from an RS-422 or RS-485 bus into single-ended CMOS/TTL logic for a UART, microcontroller, or FPGA. Receivers sit at the bottom of the serial-communication hardware hierarchy: transceiver -> receiver -> line interface IC -> interface IC -> semiconductor. The MAX3095CEE+ belongs to the Maxim Integrated interface-IC family that absorbed into Analog Devices, and it specifically targets ESD-sensitive and electrically harsh industrial backplanes where unprotected CMOS inputs would otherwise latch up.
Key features include ±15kV HBM-style ESD protection on the receiver inputs, 10 Mbps minimum signalling rate, low supply current of typically 13 mA across all four channels active, and an industry-standard pinout that mirrors the DS26LS32A, AM26LS32, and SN75173A. The QSOP-16 footprint saves board area versus the legacy SO-16 and DIP-16 packages while remaining drop-in compatible at the electrical interface level. Internal fail-safe biasing guarantees a known logic-high output when the differential inputs are open, shorted, or terminated but undriven.
Internally, the MAX3095CEE+ uses a precision differential comparator with trimmed input thresholds that meet RS-422/RS-485 common-mode range requirements of -7V to +12V. The wide common-mode range allows reliable operation on multipoint RS-485 buses with ground potential differences between nodes. Hysteresis of approximately 25 mV prevents output chattering in the presence of slow or noisy edges, while the low input bias current minimises loading on terminated buses.
Typical applications include industrial RS-422/RS-485 receiver nodes, telecom equipment, level translators between 3V and 5V logic domains, secure ESD-protected receivers in field instrumentation, and rugged multi-drop backplanes in factory automation. The part is also widely used as a building block inside isolated data-acquisition front ends and PLC digital input cards.
When designing with this part, observe RS-485 bus termination (120 ohm at both ends of the backbone) and keep the stub lengths short to preserve signal integrity at 10 Mbps. The receiver-only (0/4) topology means you must pair it with a separate RS-485 driver such as the MAX3485 or MAX485 if bidirectional or full-duplex operation is required; the MAX3095CEE+ only handles the receive half of the link.
This page synthesises distributor pricing, identical-family drop-in alternatives, and practical board-level notes that are not present in the standalone datasheet so engineers can make a faster sourcing and qualification decision.

典型应用
MAX3095CEE+ 适用于 6 应用s: Industrial RS-485 Receiver Nodes, Telecom Equipment Line Receivers, 3V to 5V Logic Level Translators, ESD-Sensitive Instrumentation Receivers, Factory Automation Multi-Drop Backplanes, Ruggedised RS-422/RS-485 Receivers.
Industrial RS-485 Receiver Nodes
The MAX3095CEE+ is well-suited to industrial RS-485 receiver nodes because its ±15kV IEC-style ESD protection on every differential input survives the static-discharge events common at field wiring terminals and connector mating surfaces. Its -7V to +12V common-mode input range tolerates ground-potential differences between PLC cabinets and remote sensors, while the 10 Mbps data rate comfortably exceeds the requirements of Modbus RTU, PROFIBUS-DP, and most factory-automation backbones. Place the part at the bus end with a 120 ohm termination resistor to match RS-485 cable impedance, and connect RO1..RO4 directly to the MCU UART pins - no external Schmitt triggers or hysteresis stages are required.
推荐
Telecom Equipment Line Receivers
In telecom shelf and central-office equipment, the MAX3095CEE+ functions as a rugged quad receiver for backplane serial links such as RS-422 distribution of timing and supervision signals. ±15kV ESD withstand rating prevents latch-up during installation and field service, while the wide 5V supply tolerance (4.75V to 5.25V) accommodates the supply-rail variation typical of telecom -48V-isolated intermediate buses. The QSOP-16 footprint keeps the part small enough to mount multiple receivers on a single line card without crowding the high-density backplane connector. Use it together with the MAX3095/3096's companion drivers in any equipment needing fault-tolerant 5V serial I/O.
推荐
3V to 5V Logic Level Translators
The MAX3095CEE+ is frequently deployed as a logic-level translator stage when a 3.3V microcontroller must receive 5V RS-485 differential signals. Its differential input thresholds of ±200 mV accept swings as small as 200 mV peak-to-peak and reject ground shifts up to ±7V, while the CMOS-compatible logic outputs can drive 3.3V input pins if the 5V VCC is selected appropriately to the downstream side. This combination of differential receiving and level shifting eliminates the need for dedicated level-translator ICs. Although dedicated MAX3370/MAX3390 parts exist for unidirectional 3V-to-5V translation, the MAX3095CEE+ provides the same function over the RS-485 bus in addition to its receiver role.
推荐
ESD-Sensitive Instrumentation Receivers
ESD-sensitive instrumentation applications, such as bench-top oscilloscopes and data-acquisition front ends, benefit from the MAX3095CEE+ because its ±15kV input ESD withstand rating protects downstream ADCs and FPGAs from cable-discharge events during connection of scope probes or sensor leads. Combined with the wide common-mode range of -7V to +12V, the receiver tolerates ground differences between the bench instrument under test and the test set itself. Place the receiver directly behind the BNC or D-sub connector, follow it with a series ferrite, and terminate into a precision low-leakage ADC.
推荐
Factory Automation Multi-Drop Backplanes
Factory automation backplanes running RS-422 or RS-485 multi-drop links at 2 Mbps to 10 Mbps benefit from the MAX3095CEE+ because its internal fail-safe biasing ensures a defined logic-high output when no driver is active, eliminating the need for external pull-up/pull-down resistors on the bus. Each receiver output can drive a 5V PLC input directly, and the wide package pitch supports automated optical inspection in volume manufacturing. The 70 mV minimum differential input sensitivity detects weak signals at the end of long daisy-chained backplanes where attenuation is significant.
推荐
Ruggedised RS-422/RS-485 Receivers
System designers commonly pair the MAX3095CEE+ with isolated DC-DC converters and digital isolators to build ruggedised receiver blocks for harsh industrial environments. The part's ±15kV ESD protection is the first line of defence, withstanding field wiring transients and human-body discharge; an isolator such as the MAX3150 or ADuM1401 follows the receiver outputs to break ground loops. The QSOP-16 footprint mounts inside compact IP65 enclosures used in field instrumentation. Per the datasheet, the receiver draws only 13 mA from a 5V supply, easing thermal management and simplifying thermal shutdown protection.

设计说明
Place the MAX3095CEE+ as close as possible to the bus connector so that the ±15kV ESD protection is positioned to absorb discharge events at the boundary rather than deep inside the PCB. Keep the receiver input traces short and symmetric (equal length for RI+ and RI-) so that any common-mode noise couples equally into both inputs and is rejected by the differential comparator. Add 100 Ω series termination resistors at each differential input if the cable length exceeds 30 m; for shorter links, 10 Ω inline ferrite beads often provide adequate ringing suppression without disturbing the 100 Ω bus impedance.
The MAX3095CEE+ draws up to ~13 mA from a 5V supply, so a 100 mA LDO (or even a ferrite-bead plus a local 10 µF + 100 nF decoupling pair) suffices for stable operation. Place a 100 nF X7R capacitor within 5 mm of the VCC pin and a 10 µF tantalum or ceramic capacitor within 25 mm to handle transient current steps during high-speed data transitions. Sharing the analog VCC with digital logic can inject switching noise into the receive inputs; if bit error rates spike, switch to a dedicated, lightly loaded supply rail.
The receiver outputs are totem-pole CMOS and should not be tied together; each receiver is meant to drive its own load. Driving more than about 4 mA from a single RO pin exceeds the part’s rated output current and can trigger latch-up. Also be sure the bus is properly terminated with 120 Ω resistors at both ends and that stub lengths are less than one-tenth of the unit interval at the operating data rate - violations generate reflections and intermittent errors that look like ESD noise but are not.
