Frequently Asked Questions
How many RS-232 channels does the TL145406N provide?
The TL145406N provides three complete RS-232 channels, each with one driver and one receiver, for a total of 3 drivers and 3 receivers in a single 16-pin DIP package. This makes it suitable for multi-port serial communication designs where space and component count must be minimized compared to using multiple single-channel transceiver ICs.
What RS-232 standards is the TL145406N compliant with?
The TL145406N is compliant with EIA-232-F, TIA-232-F, and V.28 serial interface standards. All receiver inputs feature Schmitt trigger hysteresis with a maximum high-level input current of 10µA, ensuring reliable signal detection even in the presence of noise, ground loops, and cable-induced interference common in industrial RS-232 installations.
What package is the TL145406N available in?
The TL145406N is packaged in a 16-pin dual in-line package (PDIP) with JESD-30 code R-PDIP-T16, suitable for through-hole PCB assembly. The lead-free designation (JESD-609 code e4, Pbfree Code: Yes) confirms RoHS compliance for use in products sold in regulated markets.
Does the TL145406N require external capacitors?
Yes, like most RS-232 transceivers, the TL145406N requires external charge pump capacitors to generate the required RS-232 output voltage swing (typically ±5V to ±9V) from a single 5V supply. Typically four capacitors in the 100nF to 1µF range are connected to the charge pump pins as specified in the Texas Instruments datasheet.
