SN75185 Multiple RS-232 Drivers and Receivers SMD (SOIC-20)

The SN75185 is a robust, single-chip solution designed to facilitate seamless communication between a Universal Asynchronous Receiver-Transmitter (UART) and serial-port connectors. This device combines three drivers and five receivers from the industry-standard SN75188 and SN75189 series into a unified 20-pin SMD package, significantly reducing board space and component count. It is engineered to meet the stringent TIA-EIA-232-F standards, ensuring reliable data interchange between host computers and peripherals. With its flow-through pinout design, the SN75185 allows for easy PCB routing and interconnection. This transceiver is particularly well-suited for legacy computer interfaces, industrial controllers, and any system requiring a rugged, low-cost RS-232 communication link with high ESD resilience.

Key Features:

Fully meets or exceeds the requirements of TIA-EIA-232-F and ITU v.28 standards.

Supports high-speed data signaling rates up to 120 kbit/s.

Enhanced ESD protection reaching up to 10 kV on RS-232 bus pins.

Pin-to-pin compatible with the SN75C185 for easy hardware upgrades.

Integrates three independent drivers and five receivers in one compact package.
