The TRS3318E is a dual-driver, dual-receiver, RS-232-compatible transceiver. The device features auto-powerdown plus and enhanced electrostatic discharge (ESD) protection integrated into the chip. Driver output and receiver input are protected to ±15 kV using the IEC 61000-4-2 Air-Gap Discharge method, ±8 kV using the IEC 61000-4-2 Contact Discharge method, and ±15 kV using the Human-Body Model (HBM).
The device operates at a data rate of 460 kbps. The transceiver has a proprietary low-dropout driver output stage, enabling RS-232-compatible operation from a 2.25-V to 3-V supply with a dual charge pump. The charge pump requires only four 0.1-µF capacitors and features a logic-level output (READY) that asserts when the charge pump is regulating and the device is ready to begin transmitting.
The TRS3318E achieves a 1-µA supply current using the auto-powerdown feature. This device automatically enters a low-power power-down mode when the RS-232 cable is disconnected or the drivers of the connected peripherals are inactive for more than 30 s. The device turns on again when it senses a valid transition at any driver or receiver input. Auto-powerdown saves power without changes to the existing BIOS or operating system.
This device is available in two space-saving packages: 20-pin SSOP and 20-pin TSSOP.

TIDA-060008 — 将 RS-232 信令转换为 RS-485 信令的参考设计
This reference design provides a circuit of converting RS-232 signaling to RS-485 signaling. This allows for long-distance communication, since the range supported by RS-232 is normally less than 50 feet while the range for RS-485's can exceed 1000 feet. The design implements bidirectional (...)TIDA-00540 — RS-485/RS-232 多协议收发器参考设计
