Low Power 5V 1,000kbps RS232 Transceivers
General Description
The ZT232F series devices are +5V powered EIA/TIA-232 and
CCITT V.28/V.24 communication interfaces with low power re-
quirements. These transceivers consist of two line drivers, two
line receivers and the proprietary switch-capacitor regulated
voltage converters. The ZT310F and ZT312F 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 high data rate
of 1,000k bits/sec with enhanced electrostatic discharge (ESD)
protection in all RS232 I/O pins exceeding ±15kV HBM.
