General Description

The ZT230E series devices are +5V powered EIA/TIA-232

and V.28/V.24 communication interfaces with low power

requirements. These transceivers consist of combinations

up to five line drivers, five line receivers and the proprietary

switch-capacitor regulated voltage converters. The ZT211E

and ZT213E feature a low power shutdown mode which

draws as little current as 1

µA 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) pro-

tection in all RS232 I/O pins exceeding ±15kV HBM.
