The transmitter section of each bus takes complementary CMOS / TTL Manchester II bi-phase data and converts it to differential voltages suitable for driving the bus isolation transformer. Separate transmitter inhibit control signals are provided for each transmitter. The receiver section of the each bus converts the 1553 bus bi-phase differential 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-1579) or logic 1 (HI-1581). 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 each coupling transformer. 1579PCI 1579PCT 1579PCM 1581PCI 1581PCT 1581PCM 12 13 14 15 16 17 18 19 20 21 22 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 · Compliant to MIL-STD-1553A and B, MIL-STD-1760 and ARINC 708A · 3.3V single supply operation · Smallest footprint available in 7mm x 7mm 44 pin plastic chip-scale package (QFN) 20 Pin Plastic ESOIC - WB package VDDA 1 BUSA 2 BUSA 3 RXENA 4 GNDA 5 VDDB 6 BUSB 7 20 TXA 19 TXA · Less than 0.5W maximum power dissipation and extended temperature ranges · Industrial · Industry standard pin configurations BUSB 8 RXENB 9 GNDB 10 20 Pin Ceramic DIP package (DS1579 Rev.

It is 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 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 data at the RXA/B and RXA/B output pins. When the MIL-STD-1553 bus is idle and RXENA or RXENB are high, RXA/B will be logic “0” on HI-1579 and logic “1” on HI-1581. Each set of receiver outputs can also be independently forced to the bus idle state (logic "0” on HI-1579 or logic “1” on HI-1581) by setting RXENA or RXENB low. MIL-STD-1553 BUS INTERFACE A direct coupled interface (see Figure 2) uses a 1:2.5 ratio isolation transformer and two 55 ohm isolation resistors between the transformer and the bus. In a transformer coupled interface (see Figure 3), the transceiver is also connected to a 1:2.5 isolation transformer which in turn is connected to a 1:1.4 coupling transformer. The transformer coupled method also requires two coupling resistors equal to 75% of the bus characteristic impedance (Zo) between the coupling transformer and the bus.

Transformer Coupled Test Circuits HEAT SINK - ESOIC & CHIP-SCALE PACKAGE The HI-1579PSI/T/M and HI-1581PSI/T/M use a 20-pin thermally enhanced SOIC package. The HI-1579PCI/T/M and HI-1581PCI/T/M use a plastic chip-scale package (QFN). These packages include a metal heat sink located on the bottom surface of the device. This heat sink should be soldered down to the printed circuit board for optimum thermal dissipation. The heat sink is electrically isolated and may be soldered to any convenient power or ground plane.
