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.
