Description

The ZT232E series devices are +5V powered EIA/TIA-232 and CCITT V.28/V.24 communication interfaces with low power requirements. These transceivers consist of two line drivers, two line receivers and the proprietary switch-capacitor regulated voltage converters. The ZT310E and ZT312E feature a low power shutdown mode which draws as little current as 1µA typical with receiver outputs tri-stated and in wake-up. These devices operate 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 Meets EIA/TIA-232F and CCITT V.28/V.24 specifications for Vcc at +5V ±10% Low Quiescent Current - 3mA typ., 5mA max Low Shutdown Current (where applicable) - 1µA typical, 5µA max Guaranteed Standard Data Rate 250Kbps Proprietary Switch-Capacitor Regulated Voltage Converters (patent pending) Use Small 0.1µF Capacitors Wake Up Feature (where applicable) in Shutdown Mode Tri-State Receiver Outputs Latch-up Free ESD Protection for RS-232 I/O’s ±15kV Human Body Model (HBM) Drop-in Replacements for MAX202E, MAX232E, SP202E, SP232E, SP310E, SP312E, ST202E, ST232E, HIN202E, HIN232E, ADM202E, ADM232L High Data Rate at 1000Kbps Available on ZT232F Series
