MAX202CSE+ - +5V RS-232 Transceiver | Maxim Integrated
MPN: MAX202CSE+ ✓ فعالMAX202CSE+ نمای کلی
An RS-232 transceiver is a semiconductor interface that converts between digital logic-level signals and single-ended RS-232 voltage levels. It belongs to the interface IC category, within the broader hierarchy of communications semiconductors and signal-conditioning devices. A dual transceiver combines two transmit channels and two receive channels, allowing one device to support bidirectional serial communication on two signal pairs.
The MAX202CSE+ operates from a single +5V supply and requires external 0.1µF charge-pump capacitors. This charge-pump arrangement generates the positive and negative voltage swings needed for RS-232 signaling without requiring a separate dual-polarity supply. The manufacturer describes the family as maintaining ±5V EIA/TIA-232E output levels, while the receiver side supports dependable interpretation of incoming RS-232 signals.
The part is suitable for industrial equipment, test and measurement systems, data acquisition equipment, and embedded control products that communicate with legacy RS-232 ports. Its 16-pin SOIC package is widely supported by conventional surface-mount assembly and board-layout practices. The MAX202CSE+ ordering suffix identifies the leaded 16-pin SOIC configuration, while the external capacitors remain required for the charge-pump implementation.
Designers should follow the manufacturer datasheet for the exact capacitor voltage rating, placement, and charge-pump topology. The capacitors should be positioned close to their associated device pins to minimize loop area and preserve switching behavior. Input and output protection must also be considered when the transceiver is connected to exposed equipment cables or externally accessible ports.
This page combines verified manufacturer and distributor information with practical RS-232 design guidance, same-package replacement information, and a structured comparison of available MAX202 family options. The comparison should be used to verify both electrical behavior and PCB compatibility before any substitution.

کاربردهای معمول
MAX202CSE+ مناسب است برای 6 کاربردs: Industrial Serial Control, Test and Measurement Equipment, Data Acquisition Systems, Embedded Service Console, Security and Access Equipment, Communications Adapter.
Industrial Serial Control
The MAX202CSE+ fits industrial serial-control equipment that communicates through legacy RS-232 links without a ±12V supply rail. Its +5V operating requirement simplifies the power architecture, while two drivers and two receivers can support two bidirectional channels. The manufacturer confirms operation above 120 kbps under EIA/TIA-232E loading and specifies 0.1µF external capacitors for the charge-pump network. Place those capacitors close to the device pins and route protected external connector signals through an appropriate interface network. The principal design consideration is environmental qualification: the supplied excerpts do not state the complete operating-temperature range, so industrial temperature suitability must be confirmed from the manufacturer ordering information before deployment.

Test and Measurement Equipment
The MAX202CSE+ is appropriate for test instruments and laboratory peripherals requiring an RS-232 command or control interface. The device maintains ±5V EIA/TIA-232E driver levels and exceeds 120 kbps under the manufacturer's specified loading conditions, making it suitable for moderate-speed configuration traffic. Two transmit and two receive channels allow one transceiver to manage more than one RS-232 port. Designers should keep the charge-pump capacitor loop compact, provide a stable +5V supply, and verify the complete pin configuration from the MAX202 datasheet. Because the verified excerpts do not provide a complete temperature specification or exact input thresholds, those values must be checked before selecting the part for calibrated production equipment.
پیشنهادی
Data Acquisition Systems
A MAX202CSE+ can provide a compact single-supply interface between a data-acquisition controller and legacy RS-232 equipment. Two driver/receiver pairs support multiple RS-232 signal directions, while the +5V supply requirement avoids the need for separate positive and negative rail generation beyond the IC's internal charge-pump function. The manufacturer states that the drivers maintain ±5V EIA/TIA-232E levels at data rates above 120 kbps. In practice, cable length and loading may reduce usable margin, so communication should be tested with the intended cable and peripheral. The required 0.1µF charge-pump capacitors should follow the datasheet layout closely to minimize switching-node coupling into sensitive acquisition circuitry.

Embedded Service Console
The MAX202CSE+ is useful in embedded controllers, service interfaces, and configuration ports that must connect to an RS-232 host. A single +5V rail simplifies integration where space is constrained, and the 16-pin SOIC package supports standard surface-mount assembly. The two-channel architecture can reduce component count when multiple serial functions are required. Use the manufacturer's pin configuration to assign driver outputs and receiver inputs, and preserve the specified 0.1µF charge-pump capacitors close to the relevant pins. External circuitry should protect connector-accessible signals against electrical stress. The verified evidence confirms the electrical interface and package, but it does not state the full temperature range, supply-current limits, or receiver common-mode range, so these must be verified before a safety- or mission-critical release.
پیشنهادی
Security and Access Equipment
The MAX202CSE+ can support RS-232 configuration or diagnostic connections in access-control and security equipment that already uses a +5V logic rail. Its dual driver and dual receiver arrangement accommodates multiple RS-232 signal channels, while data rates above 120 kbps are sufficient for common command and status traffic. The charge-pump implementation reduces external power-supply complexity, although external 0.1µF capacitors remain mandatory. Layout should separate connector-side and logic-side return paths where possible to reduce common-mode coupling. Verify the complete MAX202CSE+ pinout and operating limits from the manufacturer datasheet because those details are not contained in the supplied search excerpts. Any externally accessible RS-232 port also requires application-appropriate surge and ESD protection.
پیشنهادی
Communications Adapter
The MAX202CSE+ is suitable for compact RS-232 adapter and interface-converter products built around a +5V controller. Two RS-232 transmit channels and two receive channels enable multi-channel host or peripheral connectivity without duplicating the transceiver circuit. The official manufacturer information confirms ±5V EIA/TIA-232E driver output behavior and data rates in excess of 120 kbps, while DigiKey confirms the 2/2 full-duplex configuration and 16-SOIC package. Engineers should provide the specified 0.1µF external capacitors, keep charge-pump loops compact, and account for cable capacitance and receiver loading. The supplied evidence does not include numeric pricing, lead time, or full environmental ratings, so procurement and qualification decisions require direct distributor and manufacturer review.

یادداشت‌های طراحی
Place the manufacturer-specified 0.1µF charge-pump capacitors close to the corresponding MAX202CSE+ pins. Keep the capacitor-current loop compact and minimize the distance between each capacitor and the device connection. This is important because the MAX202 generates RS-232 voltage levels through a switched charge-pump network, and longer loops can increase radiated and conducted noise. Follow the exact capacitor terminals and topology shown in the manufacturer datasheet rather than inferring the arrangement from a generic RS-232 reference circuit.
Do not treat MAX202CSE+ as a no-capacitor RS-232 solution. The verified product information specifically identifies the MAX202 family as requiring 0.1µF external capacitors for its charge-pump circuit. Omitting those capacitors, changing their value, or placing them far from the IC can prevent correct operation. Also check the capacitor voltage rating and dielectric against the manufacturer recommendations, because the charge-pump nodes may experience voltage swings that are not identical to the +5V supply rail.
Separate the connector-side RS-232 route from sensitive logic and analog circuitry. Keep the transceiver near the serial connector where practical, use a controlled return path for the interface network, and place any protection components at the connector boundary. The device maintains ±5V EIA/TIA-232E driver levels, but cable transients and poor return paths can still corrupt signals. Verify the complete pinout and network topology against the MAX202 datasheet before final routing because individual pin names were not included in the supplied excerpts.
Design the +5V rail with appropriate local decoupling and verify its behavior during driver transitions. The MAX202CSE+ generates bipolar RS-232 levels from a single +5V supply through external charge-pump components, so supply and reference return paths must remain stable. The supplied evidence does not include supply-current limits or capacitor voltage ratings; obtain those values from the manufacturer datasheet and use them to select the regulator, bulk capacitance, and charge-pump capacitors before release.
اطلاعات انطباق
The supplied search results mention RoHS and REACH in generic comparison pages but do not provide authoritative compliance statements for MAX202CSE+. No compliance status has therefore been assumed. AEC-Q100 is not applicable because this is a general-purpose RS-232 interface IC rather than an automotive-qualified device.
