Ohm terminations plus additional

receivers, the data bus signal pro-

duced is 7.5 volts typical P -P at A-

A’. (See Figure 5.) When both DATA

and DATA inputs are held low or

1 MHz to meet Macair specifications

A-3818, A-4905, A-5232 and A-

5690. The transmitter may be safely

operated for an indefinite period at

100% duty cycle into a data bus

short circuit.

set to detect data bus signals

exceeding 1.05 Volts P-P and reject

signals less than 0.6 volts P-P when

used with a 1:1 turns ratio trans-

former (See Figure 5 for transformer

data and typical connection).

high,

the

transmitter

output

becomes a high impedance and is

“removed” from the line. In addition,

an overriding “INHIBIT" input pro-

vides for the removal of the trans-

mitter output from the line. A logic

“1” applied to the “INHIBIT” takes

priority over the condition of the data

inputs and disables the transmitter.

(See Transmitter Logic Wave-

forms,Figure 1.)

Receiver:

A low level at the Strobe input

inhibits the DATA and DATA out-

puts. If unused, a 2K pull-up to +5

Volts is recommended

The Receiver section accepts bi-

phase differential data at the input

and produces two TTL signals at the

output. The outputs are DATA and

DATA, and represent positive and

negative excursions of the input

beyond a pre-determined threshold.

(See Receiver Logic Waveforms,

Figure 2.)

The transmitter utilizes an active

filter to suppress harmonics above

The internal threshold is nominally

NOTES:

1. Line to line waveforms illustrate Macair signals, MIL-STD-1553 signals are trapezoidal

2. DATA and DATA inputs must be complementary waveforms or 50% duty cycle average, with no delays between them.

3. DATA and DATA must be in the same state during off time (both high or low).
