DS14C239
Dual Supply TIA EIA-232 3 x 5 Driver Receiver
General Description
The DS14C239 is a three driver five receiver device which
conforms to the TIA EIA-232-E standard and CCITT V 28
recommendations This device eliminates b12V supply by
employing an internal DC-DC converter to generate the nec-
essary output levels from a single a5V supply and a posi-
tive voltage power supply (a7 5V to a13 2V) Driver slew
rate control and receiver noise filtering have also been inter-
nalized to eliminate the need for external slew rate control
and noise filtering capacitors With the addition of
TRI-STATE receiver outputs device power consumption is
kept to a minimum
The combination of its low power requirement and extended
operating temperature range makes this device an ideal
choice for a wide variety of commercial industrial and bat-
tery powered applications
