TLF11283 March 1996 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 Features Y Conforms to TIAEIA-232-E and CCITT V28 Y Internal DC-DC converter Y Low power requirement Ia e 10 mA max ICC e 1mAmax Y Internal driver slew rate control Y Receiver Noise Filtering Y Operates above 120 kbitssec Y TRI-STATE Receiver Outputs Y Direct replacement for MAX239 Y Industrial temperature range optionDS14C239T (b40 Cto a85 C) Connection Diagram TLF11283 – 1 Order Number DS14C239N DS14C239WM DS14C239TN or DS14C239TWM See NS Package Number M24B or NA24G Functional Diagram TLF11283 – 2 TRI-STATE is a registered trademark of National Semiconductor Corporation C1996 National Semiconductor Corporation RRD-B30M66Printed in U S A |
