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.
