DESCRIPTION/ORDERING INFORMATION  
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.
