Low Power 5V 1,000kbps RS232 Transceivers
GeneralDescription
Features
The ZT232F 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
power requirements. These transceivers consist of two line
drivers, twolinereceiversandtheproprietaryswitch-capaci-
tor 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.
