Frequently Asked Questions
How many RS-232 channels does the TL145406DWE4 provide?
The TL145406DWE4 provides 3 independent RS-232 driver channels and 3 independent receiver channels in a single 16-pin SOIC package. This triple-channel configuration allows connection of multiple serial ports or devices simultaneously, reducing component count compared to using individual single-channel transceiver devices.
What interface standards does the TL145406DWE4 comply with?
The TL145406DWE4 fully complies with EIA-232-F, TIA-232-F, and ITU-T V.28 interface standards, ensuring compatibility with a wide range of serial communication equipment. These standards define RS-232 signal voltage levels, timing, and connector requirements used in serial ports, modems, and industrial communication equipment worldwide.
What are the input characteristics of the TL145406DWE4 receivers?
The TL145406DWE4 receiver inputs feature Schmitt trigger characteristics, providing hysteresis for enhanced noise immunity on slow-transitioning or noisy input signals. The maximum high-level input current is 10 µA, ensuring minimal loading on connected RS-232 signal sources and compatibility with standard RS-232 driver outputs.
What package is the TL145406DWE4 available in?
The TL145406DWE4 is available in a 16-pin SOIC (Small Outline Integrated Circuit) package designated as R-PDSO-G16. This surface-mount package provides a compact footprint for PCB integration and is compatible with standard SMT assembly processes, making it suitable for high-volume manufacturing applications.
Can the TL145406DWE4 operate from a single supply voltage?
Yes, the TL145406DWE4 includes an integrated charge pump that generates the positive and negative RS-232 voltage levels required for standard-compliant signal transmission from a single 5 V supply. This eliminates the need for external dual power supplies, simplifying board design and reducing system cost in single-supply applications.
