GD75232PWR UART Interface IC RS-232 Interface IC Mult RS232 Driver
description/ordering information
The GD65232 and GD75232 combine three
drivers and five receivers from the
Texas Instruments trade-standard SN75188 and
SN75189 bipolar quadruple drivers and receivers, respectively. The
pinout matches the flow-through design of the SN75C185 to decrease
the part count, reduce the board space required, and allow easy
interconnection of the UART and serial-port connector of an IBM
PC/AT and compatibles. The bipolar circuits and processing of the
GD65232 and GD75232 provide a rugged, low-cost solution for this
function at the expense of quiescent power and external passive
components relative to the SN75C185.
The GD65232 and GD75232 comply with the requirements of the
TIA/EIA-232-F and ITU (formerly CCITT) V.28 standards. These
standards are for data interchange between a host computer and a
peripheral at signaling rates up to 20 kbit/s. The switching speeds
of these devices are fast enough to support rates up to 120 kbit/s
with lower capacitive loads (shorter cables). Interoperability at
the higher signaling rates cannot be expected unless the designer
has design control of the cable and the interface circuits at both
ends. For interoperability at signaling rates up to 120 kbit/s, use
of TIA/EIA-423-B (ITU V.10) and TIA/EIA-422-B (ITU V.11) standards
is recommended.
