+5V Supply EIA/TIA-232 3 x 5 Driver Receiver
DS14C535
+5V Supply EIA/TIA-2323x5 Driver/Receiver
General DescriptionThe DS14C535is three driver, five receiver device which
conformsto EIA/TIA-232-E and CCITT (ITU-T) V.28 stan-
dard specifications. This device employsan internal DC-DC
converterto generate the necessary output levels froma
+5V power supply.A SHUTDOWN (SD) mode reduces the
supply currentto10µA maximum.In the SD mode, one
receiveris active, allowing ring indicator (RI)tobe moni-
tored. PC Board space consumptionis minimizedby the
availabilityof Shrink Small Outline Packaging (SSOP).
The DS14C535 providesa one-chip solutionforthe common
9-pin serial RS-232 interface between data terminal and
data circuit-terminating equipment.
This device allows an easy migration pathto the 3.3V
DS14C335. The packages are the same. The N/C pinson
the DS14C535 are not physically connectedto the chip.
Board layoutfor the DS14C335will accommodate both de-
vices.
This device’s low power requirement and small footprint
makesitan ideal choicefor Laptop and Notebook applica-
tions.
