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 !

They are intended for applications using a MIL-STD-1553 A/B data bus. The device produces a trapezoidal output waveform during transmission. TRANSMITTER Data input to the device’s transmitter section is from the complementary CMOS /TTL inputs TXA/B and TXA/B. The transmitter accepts Manchester II bi-phase data and converts it to differential voltages on BUSA/B and BUSA/B. The transceiver outputs are either direct or transformer coupled to the MIL-STD-1553 data bus. Both coupling methods produce a nominal voltage on the bus of 7.5 volts peak to peak. The transmitter is automatically inhibited and placed in the high impedance state when both TXA/B and TXA/B are either at a logic “1” or logic “0” simultaneously. A logic “1” applied to the TXINHA/B input will force the transmitter to the high impedance state, regardless of the state of TXA/B and TXA/B. RECEIVER The receiver accepts bi-phase differential data from the MIL-STD-1553 bus through the same direct or transformer coupled interface as the transmitter. The receiver’s differential input stage drives a filter and threshold comparator that produces CMOS/TTL data at the RXA/B and RX.
