DD-03182

DD-03182 SERIES ARINC 429 LINE DRIVER DESCRIPTION The DD-03182 device is a line driver chip that transmits data on the serial data bus in accordance with the “ARINC Specification 429 Mark 33 Digital Information Transfer System” www.DataSheet4U.com (ARINC 429). This device can be used with DDC’s DD-03296 discrete-to-digital device, in conjunction with the DD03282 transceiver chip or the DD00429 microprocessor interface. The line driver receives TTL information on the DataA/DataB input pins and transmits it out on the AOUT/BOUT output pins. The output voltage level is programmable via the VREF input pin. The output pins are also protected against short circuits from aircraft power. The slew rate of the DD-03182 can be programmed for either High (100 kbit) or Low (12.5 kbit) speed via two external timing capacitors connected to the CA/CB input pins. FEATURES Plastic 14-Pin SOIC Package Available with or without Fuse Pin-For-Pin Alternative for Most Harris/Holt/Raytheon Applications APPLICATIONS The DD-03182 can be used for many different applications ranging from flight critical to nonessential. Surface mount, DIP and PLCC package configurations are available. Military temperature range is also available if required.
