HI-1567, HI-1568
March 2001
DESCRIPTION
The HI-1567 and HI-1568 are low power CMOS dual transceivers designed to meet the requirements of MIL-STD-1553 /1760 specifications.

The transmitter section of each channel takes complimentary 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 the each channel converts the 1553 bus bi-phase data to complimentary 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-1567) or logic 1 (HI-1568). 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. For designs requiring independent access to transmitter and receiver 1553 signals, please contact your Holt Sales representative.

FUNCTIONAL DESCRIPTION
The HI-1567 family of data bus transceivers contain differential voltage source drivers and differential receivers. They are intended for applications using a MIL-STD-1553 A/B data bus. The device produces a trapezoidal output waveform during transmission. TRANSMITTER RECEIVER Data input to the transmitter section of these devices is from the complimentary CMOS /TTL inputs TXA/B and TXA/B. This produces a nominal 30V peak to peak signal across a 140 ohm load. The transmitter is connected to the bus via a 1:2.5 transformer whose secondary is connected to two 52 ohm isolation resisters which feed the terminated 70 ohm bus. This will produce a nominal voltage on the bus of 7.5 volts peak to peak. The receiver is transformer coupled to the bus by a 1:1 transformer. Its differential input stage drives a filter and threshold comparator. CMOS/TTL data is outputted at the RXA/B and RXA/B pins. The receiver outputs can both be forced to a logic "0" (HI-1567) or logic "1" (HI-1568) by setting RXENA or RXENB low. 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
