Frequently Asked Questions
What are the key electrical specifications of the TRS3243EIPW?
The TRS3243EIPW operates from a 3.3V or 5V single supply and provides 3 RS-232 transmitters and 5 receivers. Transmitter output voltage typically exceeds ±5V, and the device complies with EIA/TIA-232-F standards. Maximum high-level input current is 1µA, and inputs feature Schmitt-trigger characteristics for enhanced noise immunity.
What applications is the TRS3243EIPW suitable for?
The TRS3243EIPW is ideal for industrial control systems, embedded computing boards, handheld instruments, and any design requiring multiple RS-232 serial ports. Its support for 3.3V operation makes it especially useful in modern low-power designs that interface with legacy RS-232 equipment such as modems, PLCs, barcode scanners, and GPS modules.
What package does the TRS3243EIPW come in and are there pin-compatible alternatives?
The TRS3243EIPW is packaged in a 28-pin TSSOP (Thin Shrink Small Outline Package), which is compact and suitable for space-constrained PCB layouts. Pin-compatible or functionally similar alternatives include the MAX3243 from Maxim Integrated and the SP3243 from Sipex/Exar, all sharing the same 3 TX / 5 RX RS-232 architecture.
How does the integrated charge pump in the TRS3243EIPW work?
The TRS3243EIPW contains an internal charge pump that generates the ±5V to ±15V RS-232 voltage levels required for transmission, using only four small external capacitors. This eliminates the need for a separate bipolar power supply, simplifying board design and reducing component count in single-supply 3.3V or 5V systems.
