DEI3182A ARINC 429 DIFFERENTIAL LINE DRIVE

PublishTime：2022-09-20

Description The DEI3182A is a complete differential line driver IC. When Data A = Data B or Sync or Clock Signal is low, the driver forces the output to a Voltage Null level (0V ± 250 mV). Designed to address the ARINC 429 Standard, the DEI3182A has output rise and fall times that can be adjusted by the selection of an external capacitor (CA or CB) and an output voltage range adjustable through an externally applied VREF signal. All logic inputs and sync control inputs are TTL/CMOS compatible. The device is constructed on a monolithic IC using a junction-isolated bipolar process. SiCr resistors in the internal bias circuitry provide for stable bias currents and a tighter tolerance of output impedance. The DEI3182A is available in 16-lead ceramic side-brazed DIP and can be ordered with MIL-STD-883B burn-in screening.
●Functional Description
■The device contains three main functional blocks. The first block is a digital section used to decode the ARINC Clock, Synchronization, and Data inputs as shown in Block Diagram. This block takes these inputs and channels the data to the charge pump circuits. The logical relationship for these pins is presented in Table 1.
●FEATURES • Adjustable rise and fall times • Low supply current • Capable of driving 30 nF || 400W • Digitally selectable 12.5 or 100 kbit/sec data rate • Adjustable output voltages swing • Output over-voltage protected • Short circuit tolerant • TTL and CMOS compatible inputs • MIL-STD-883B burn-in screening available • Package Options:16L SB DIP, 16L CERDIP, 28L CLCC • Direct replacement for Fairchild/Raytheon RM3182A
