DEI1270A-MMS-G数据手册DEI中文资料规格书

描述 Description

The DEI1270A/DEI1271A bipolar integrated circuits are dual line drivers designed to directly drive the ARINC 429 avionics serial digital data bus. The device converts TTL/CMOS serial input data to the tri-level RZ bipolar differential modulation format of the ARINC bus. A TTL/CMOS control input selects the output slew rate for HI (100KBS) and LOW (12.5KBS) speed operation. No external timing capacitors are required. A429 output tri-state capability is enabled by the TS_CTL input.
