General 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 HBM.

Applications
• Single Power Supply Applications
• Industrial and Embedded PCs
• Set Top Boxes
• Terminal Adapters
• POS terminals
• Peripherals Interface
• Routers and HUBs
