DS14C239

Dual Supply TIAEIA-2323x5 DriverReceiver

General Description

The DS14C239 is a three driver five receiver device which

conforms to the TIAEIA-232-E standard and CCITT V28

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 (a75V to a132V) 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
