Description
The TRS3243EIPWR is a triple transmitter quint receiver IC from Texas Instruments (TI) that provides a single-chip, single-supply interface for IBM PC/AT serial ports. It features ESD protection up to ±15-kV HBM and operates with a 3-V to 5.5-V supply voltage. The device meets or exceeds TIA/EIA-232-F and ITU v.28 standards, transmitting data at rates up to 500 kbit/s. It also has low standby current (1 µA typical) and accepts 5-V logic input with a 3.3-V supply.
The TRS3243EIPWR is designed for industrial automation, point-of-sale terminals, and data acquisition systems, providing robust and reliable serial communication interfaces in harsh environments. Its features include auto-powerdown to disable driver outputs when no valid signal is sensed, making it suitable for applications where power consumption is a concern.
