The transmitter section of each channel takes complementary CMOS / TTL digital input data and converts it to bi-phase Manchester encoded 1553 signals suitable for driving the bus isolation transformer. Separate transmitter inhibit control signals are provided for each transmitter. The receiver section of each channel converts the 1553 bus bi-phase data to complementary CMOS / TTL data suitable for inputting to a Manchester decoder. Each receiver has a separate enable input which can be used to force the output of the receiver to a logic 0 (HI-1565) or logic 1 (HI-1566). To minimize the package size for this function, the transmitter outputs are internally connected to the receiver inputs, so that only two pins are required for connection to www.DataSheet4U.com each coupling transformer. 1565PCI 1565PCT 1566PCI 1566PCT 33 32 31 TXINHA 30 RXA 29 RXA 28 27 26 TXB 25 TXB 24 TXINHB 23 - 44 Pin Plastic 7mm x 7mm Chip-scale package VDDA 1 BUSA 2 BUSA 3 RXENA 4 GNDA 5 VDDB 6 BUSB 7 BUSB 8 RXENB 9 GNDB 10 20 19 18 17 16 15 14 13 12 11 TXA TXA TXINHA RXA RXA TXB TXB TXINHB RXB RXB FEATURES ...
