TRS207IDB

Drivers, Receivers, Transceivers Overview

The TRS207IDB is a 5-V multichannel RS-232 line driver/receiver manufactured by Texas Instruments. It integrates five line drivers, three line receivers, and a dual charge-pump circuit within an SSOP-24 package. The device operates at data signaling rates up to 120 kbit/s with a maximum driver output slew rate of 30 V/µs. It requires four external 0.1-µF capacitors for the charge pump and functions from a single 5-V supply (4.5 V to 5.5 V). The component provides ±15-kV ESD protection on RS-232 bus pins per the Human-Body Model and meets TIA/EIA-232-F standards.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DB' corresponds to the SSOP-24 tube packaging configuration. Confirm that the 'I' designation indicates the industrial temperature range of -40°C to +85°C. Ensure the procurement source provides the official datasheet SLLS809 for accurate pinout and electrical characteristic verification before integration into designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a design requires five transmit channels and three receive channels in a compact SSOP-24 footprint. It is suitable for applications needing robust ESD protection on serial ports without requiring external voltage generation circuits. Verify that the system power supply remains stable between 4.5 V and 5.5 V to ensure compliance with the specified operating conditions.

Drivers, Receivers, Transceivers Part Context

The TRS207 belongs to the TRS207 family of 5-V multichannel RS-232 transceivers. The IDB suffix specifically denotes the industrial temperature grade (-40°C to +85°C) housed in a plastic SSOP-24 package. This variant is part of Texas Instruments' standard interface IC lineup designed for asynchronous communication controllers interfacing with serial-port connectors.
