TRS3232E屬于集成電路（IC）的驅(qū)動器接收器收發(fā)器。由美國德州儀器公司制造生產(chǎn)的TRS3232E驅(qū)動器，接收器，收發(fā)器該系列產(chǎn)品的主要功能是提供必需的硬件資源，以通過延長電纜或印制線進(jìn)行通信。確切的功能會因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類的功能，這些功能對于通信用途可能并非絕對必要，但對于可能的使用環(huán)境卻是明智之選。

DESCRIPTION

The TRS3232E device consists of two line drivers, two line receivers, and a dual charge-pump circuit with

±15-kV IEC ESD protection pin to pin (serial-port connection pins, including GND). The device meets the

requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication

controller and the serial-port connector. The charge pump and four small external capacitors allow operation from

a single 3-V to 5.5-V supply. The devices operate at data signaling rates up to 250 kbit/s and a maximum of

30-V/ms driver output slew rate.
