Detailed Description
The MAX3188E/MAX3189E are EIA/TIA-232 transmitters
that convert CMOS/TTL logic levels to RS-232 signals.
They operate on ±4.5V to ±6V supplies and feature
enhanced electrostatic discharge protection (see ESD
Protection). The MAX3188E guarantees a 250kbps data
rate, and the MAX3189E guarantees a 1Mbps data rate
with worst-case loads of 3k
in parallel with 1000pF.
The MAX3188E/MAX3189E invert the TOUT signal relative
to TIN (standard RS-232). The transmitter input does
not have a pull-up resistor and should be connected to
GND if unused.
Shutdown
The MAX3188E/MAX3189E feature a shutdown input.
Drive SHDN low to reduce the supply current to 1A
(max). Shutdown also forces TOUT into a high-imped-
ance state, allowing the signal line to be safely con-
trolled by other transmitters. Drive SHDN high for
normal operation.
ESD Protection
As with all Maxim devices, ESD protection structures are
incorporated on all pins to protect against ESD encoun-
tered during handling and assembly. The MAX3188E/
MAX3189Es’ transmitter output has extra protection
against static electricity. Maxim has developed state-of-
the-art structures enabling this pin to withstand ESD up
