Description

The MAX823REUK+T is a Maxim (now Analog Devices) dual RS-232 transceiver. It contains two drivers and two receivers that translate between TTL/CMOS logic levels and RS-232 voltage levels. It operates from a single 5V supply and uses an internal charge-pump to generate the RS-232 voltage swings required for communication. Only a handful of external capacitors are needed (per the datasheet). The suffix REUK+T denotes RoHS-compliant, UK packaging with Tape & Reel. Typical applications include interfacing a microcontroller or MCU UART to a PC serial port, modem, or other RS-232 devices. Advantages include low power, small footprint, and simplified external component count compared with discrete solutions.

Equivalent

MAX823REUK+T is a MAXIM microprocessor reset/voltage supervisor. Common cross-refs:
- TI: TLV803 / TLV803-Q1
- Microchip: MCP130 / MCP131 / MCP132 / MCP134
- ON Semiconductor: NCP301 / NCP302
Note: choose by Vcc range and reset thresholds; provide supply voltage, desired reset delay, and reset polarity for exact matching.

Pinout

Pin count: 8 pins (SOIC-8).
Function: MAX823REUK+T is a switched-capacitor voltage inverter/charge-pump regulator that generates a negative supply rail from a positive single-ended supply (used to power RS-232 level shifters and similar circuits). The +T suffix denotes Tape-and-Reel packaging; REUK is a regional/lead-free code variant.

Manufacturer

- Manufacturer: Maxim Integrated (now part of Analog Devices)
- What kind of company: A multinational American semiconductor company that designs and manufactures analog and mixed-signal integrated circuits.

Application

MAX823REUK+T is an RS-232 transceiver. Common application areas:
- Interface between microcontrollers/MCUs and RS-232 serial ports
- Data-communication equipment (modems, routers, switches, serial consoles)
- Computers, printers, and other peripherals with RS-232 links
- Instrumentation and test equipment requiring RS-232 interfaces
- Point-of-sale terminals and industrial controllers
- Any system needing a robust, low-power driver/receiver to convert TTL/CMOS logic to ±RS-232 levels

Package

MAX823REUK+T is in an 8-pin small-outline package (SOIC-8, SOP-8) with Tape‑and‑Reel packaging.
