ZT232E Low Power 5V 250kbps RS232 Transceivers Zywyn Corporation ZT202E/232E/310E/312E ZT202E, ZT232E ZT310E, ZT312E Zywyn Low Power 5V 250kbps RS232 Transceivers General Description Features The ZT232E series devices are +5V powered EIA/TIA-232 Meets EIA/TIA-232F and CCITT V.28/V.24 specifi- and CCITT V.28/V.24 communication interfaces with low cations for V at +5V 10% CC power requirements. These transceivers consist of two line Low Quiescent Current 3mA typ., 5mA max. drivers, two line receivers and the proprietary switch-capaci- Low Shutdown Current (where applicable) - 1A tor regulated voltage converters. The ZT310E and ZT312E typical, 5A max. feature a low power shutdown mode which draws as little current as 1A typical with receiver outputs tri-stated and in Guaranteed Standard Data Rate 250kbps wake-up. These devices operate from a single +5V power Proprietary Switch-Capacitor Regulated Voltage supply at the guaranteed data rate of 250k bits/sec with Converters (patent pending) enhanced electrostatic discharge (ESD) protection in all Use Small 0.1F Capacitors RS232 I/O pins exceeding 15kV HBM.
