MAX202ECSE.TG096 - 5V RS-232 Transceiver | Maxim Integrated
料号： MAX202ECSE.TG096 ✓ 量产中MAX202ECSE.TG096 概述
An RS-232 transceiver is an interface IC that translates between digital logic levels and RS-232 voltage levels. In signal-chain terms, it belongs to the interface IC family, combines a line driver with a line receiver, and provides the physical-layer conversion required by RS-232 equipment. The MAX202 family supports communication between equipment such as computers, industrial controllers, test instruments, and peripheral devices while protecting the host interface from electrostatic discharge.
The MAX202ECSE.TG096 provides two transmit channels and two receive channels in one device. Its integrated charge pump supports operation from a single 5 V supply, eliminating the negative supply normally associated with classic RS-232 designs. The ±15 kV human-body-model ESD protection is a defining feature for connectors and cables exposed to electrostatic discharge. Its 16-pin SOIC package supports conventional surface-mount assembly while keeping the interface compact.
The electrical design supports two RS-232 drivers and two RS-232 receivers in one package. Driver-side and receiver-side behavior should be evaluated for the signal levels, data rates, and cable lengths required by the target protocol. Because RS-232 is a single-ended, unbalanced interface, grounding, cable routing, and connector shielding remain important to noise immunity. The MAX202ECSE.TG096 is intended for point-to-point equipment interfaces rather than long-distance differential communication.
Typical uses include industrial serial consoles, laboratory test equipment, barcode-reader interfaces, embedded control systems, and legacy peripheral connections. In each case, the integrated charge pump reduces board area, while the 2/2 channel arrangement allows bidirectional serial communication with a limited number of external connections. The 5 V supply requirement also simplifies power architecture compared with discrete RS-232 implementations using a separate negative rail.
Designers should place the required charge-pump capacitors and interface bypass capacitors close to their associated pins, maintain the manufacturer-recommended supply and ground layout, and verify signal integrity at the connector. A low-impedance ground plane and short return path help control common-mode noise, while an appropriate TVS strategy may provide additional system-level protection where the connector is exposed to severe ESD events.
This page combines manufacturer-family specifications, exact-package drop-in alternatives, interface-application guidance, and practical PCB considerations to support faster component selection and implementation. Use the MAX202ECSE.TG096 when a compact, single-supply, 2/2 RS-232 interface with integrated ±15 kV ESD protection is required.

典型应用
MAX202ECSE.TG096 适用于 6 应用s: Industrial Serial Console Interfaces, Laboratory Test Equipment, Embedded Controller Serial Links, Barcode and Data Collection Equipment, Legacy Peripheral Connectivity, Network Equipment Management Ports.
Industrial Serial Console Interfaces
The MAX202ECSE.TG096 fits industrial serial-console designs that need two driver and two receiver channels on one 5 V board. Its integrated charge pump removes the need for a separate negative RS-232 supply, reducing board area and power-tree complexity. The ±15 kV HBM ESD protection is valuable when the console connector is exposed to charged cables or maintenance events. Place the charge-pump capacitors close to the IC and route the interface ground to the connector shield through a controlled low-impedance path. A two-driver/two-receiver arrangement supports bidirectional console communication while keeping the external footprint within a compact 16-pin SOIC package.
推荐
Laboratory Test Equipment
The MAX202ECSE.TG096 is suitable for laboratory instruments that exchange RS-232 control or measurement data with a host computer. Two driver channels support outbound command and status signals, while two receiver channels accept incoming control traffic. The single 5 V supply is convenient for compact instrument architectures, and integrated charge-pump circuitry avoids a discrete negative rail. The ±15 kV HBM rating improves connector robustness during routine laboratory cabling. Place bypass capacitance at the 5 V pin, keep the charge-pump loop compact, and connect the RS-232 ground reference close to the cable shield to minimize common-mode pickup.
推荐
Embedded Controller Serial Links
The MAX202ECSE.TG096 can provide legacy RS-232 connectivity for an embedded controller, service console, or configuration port. The 2/2 channel arrangement allows two serial paths without using two separate transceiver packages, while the 5 V operating requirement simplifies power distribution beside digital logic. Integrated charge-pump circuitry generates the required driver voltage internally. The device's ±15 kV HBM protection strengthens a port that may connect to an external programming cable. Designers should separate the noisy RS-232 return path from sensitive analog grounds where practical and follow the manufacturer capacitor-placement requirements for predictable charge-pump behavior.
推荐
Barcode and Data Collection Equipment
The MAX202ECSE.TG096 suits barcode scanners, data-collection terminals, and service equipment that communicate through an RS-232 host port. Two transmit and two receive channels provide enough connectivity for common control-and-data configurations without duplicating driver circuitry. Its integrated charge pump supports a compact 5 V design, which is useful when the interface shares a supply with embedded processing electronics. The ±15 kV HBM ESD protection adds defense at an exposed scanner or programming connector. Use short, properly grounded RS-232 traces and verify the selected channel mapping against the connector wiring before production release.
推荐
Legacy Peripheral Connectivity
The MAX202ECSE.TG096 is useful for adding an RS-232 port to newer control hardware that must communicate with legacy printers, scales, programmers, or service peripherals. The MAX202E family supports RS-232 and V.28 signaling and includes an integrated charge pump for single 5 V operation. This reduces the circuitry required compared with a discrete driver arrangement requiring a negative voltage. The 16-pin SOIC package is straightforward to route on standard surface-mount boards. Keep the connector-side ground reference continuous, avoid long unprotected stubs, and confirm cable length and data rate against the V.28 system requirements.
推荐
Network Equipment Management Ports
The MAX202ECSE.TG096 can support an RS-232 management or diagnostic port on networking equipment where a service technician connects a laptop or terminal. Two driver and receiver channels allow console and auxiliary serial functions on a compact board. Single 5 V operation simplifies auxiliary power distribution, while ±15 kV HBM ESD protection is useful because management connectors are frequently touched during installation and service. Route the interface as a controlled impedance-free differential pair per the manufacturer's layout guidance, keep the connector return adjacent to the signal conductors, and provide adequate bypass capacitance to prevent interface noise from disturbing adjacent switching circuitry.

设计说明
Place all charge-pump capacitors directly beside their associated MAX202ECSE.TG096 pins, and place 5 V bypass capacitance at the supply pin with a short return path to the ground plane. Keep the charge-pump loop compact to reduce radiated and conducted noise. Avoid routing the RS-232 driver outputs beneath sensitive digital or analog sections because their transitions are intentionally high amplitude and fast enough to create crosstalk.
Use a continuous RS-232 ground reference between the transceiver and connector, and place it adjacent to the signal conductors where practical. RS-232 is unbalanced, so common-mode voltage and ground offsets can affect receiver performance. Keep external protection components close to the connector entry point, preserve the manufacturer's pin orientation, and inspect the assembled board for accidental copper coupling between charge-pump nodes and receiver inputs.
Do not assume that every MAX202 family suffix has the same qualification, temperature, or lifecycle conditions even when the package and pinout match. Validate the complete ordering code against the intended industrial, automotive, or commercial environment. Also confirm that the connected equipment uses compatible RS-232 levels and that the cable length, data rate, and ground arrangement satisfy the selected V.28 implementation.
The integrated charge pump can couple periodic noise into the supply rail. Decouple the IC locally and avoid sharing narrow supply traces with sensitive loads. If the board includes switching converters, keep their high-current loops away from the RS-232 connector and receiver section. A solid ground plane and short capacitor connections generally provide a more effective EMI control than adding filtering inside the signal path.
