Descripción general

Description

SN75189ADR is a Texas Instruments serial communications IC in the SN75189 family. It’s a dual asynchronous UART-style interface used to connect a microcontroller or processor to serial devices. The device provides transmitter and receiver functionality that lets you convert between TTL/CMOS logic levels and the signals used on serial lines (often RS-232 level signaling when paired with a suitable line driver). Typical use cases include modem interfaces, computer/terminal ports, and other serial data paths in microprocessor systems. It is designed for 5V operation and TTL/CMOS compatible I/O, with standard UART framing (start/stop bits, data bits, parity options) for asynchronous communication. For exact pinout, electrical characteristics, baud capability, and package details, consult the SN75189ADR datasheet.

Features

Please confirm the exact part function. TI SN75189ADR could refer to an RS-232 line driver/receiver pair or another TI SN75189 variant.
If it is an RS-232 transceiver (dual drivers/receivers), typical features include:
- Dual RS-232 line drivers and two receivers
- Single 5 V supply
- TTL/CMOS-compatible input thresholds
- RS-232 level outputs (positive/negative swings)
- Full-duplex operation with separate driver/receiver enable
- Tri-state (high-impedance) outputs when disabled
- Short-circuit/overload protection
Provide the datasheet link or confirm the function and I’ll list the exact, model-specific features.

Package

SN75189ADR is the TI variant packaged in a 16-pin Small Outline Integrated Circuit (SOIC) package.

Manufacturer

The SN75189ADR is manufactured by Texas Instruments Incorporated (TI). TI is an American multinational semiconductor company that designs and manufactures a broad range of integrated circuits and other electronics components for global markets.

Application

- Data buffering and I/O expansion for microprocessors
- Serial/parallel data conversion in communications and peripherals
- Timing, sequencing and state-machine control
- Data shifting for display drivers and LED matrices
- Interface logic in telecom, instrumentation, and test equipment
- Prototyping and development in digital systems

Equivalent

SN75189ADR is an 8‑bit bidirectional bus transceiver with 3‑state outputs. Equivalents include the 74xx245 family: TI SN74LS245, SN74ALS245, SN74HC245, SN74HCT245. Other vendors provide the same function as 74HC245/74HCT245 (e.g., NXP 74HC245, ST 74HC245, Renesas, Onsemi). Ensure matching voltage levels and packaging when selecting a cross‑reference.
