Low Power 5V 250Kbps RS232 Transceivers (Features 16-pin, ±9V Output Voltage Swing)

Add Favorites


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. 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 HBM.
