Description

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 of TRS3318E are pro tected 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 TRS3318E operates at a data rate of 460 kbps. The transceiver has a proprietary low-dropout driver output stage, ena bling 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-Fcapacitors and features a logic-level output (READY) that asserts when the charge pump of TRS3318E  is regulating and the device is ready to begin transmitting.

The TRS3318E achieves a 1-A supply current using the auto-powerdown feature. This device automatically enters a lo w-power power-down mode when the RS-232 cable is disconnected or the drivers of the connected peripherals are ina ctive for more than 30 s. The TRS3318E turns on again when it senses a valid transition at any driver or receiver input. uto-powerdown saves power without changes to the existing BIOS or operating system.

This TRS3318E is available in two space-saving packages: 20-pin SSOP and 20-pin TSSOP.
