Product Summary
The ZT2109-D is a Low Power 5V 250kbps RS232 Transceiver. The transceiver consists of combinations up to fi ve line drivers, five line receivers and the proprietary switch-capacitor regulated voltage converters. The ZT2109-D features a low power shutdown mode which draws as little current as 1μA typical with receiver outputs tri-stated and in wake-up. The device operates from a single +5V power supply at the guaranteed data rate of 250k bits/sec with enhanced electrostatic discharge (ESD) protection in all RS232 I/O pins exceeding ±15kV HBM. The applications of the ZT2109-D include Battery-Powered Applications, Notebooks, Subnotebooks, and Palmtops, Industrial and Embedded PCs, Data Cables for Cell Phones and PDAs, Terminal Adapters and POS terminals, Peripherals interface, Routers and HUBs.
