Notes:

2. All typical values are measured at +25°C.

3. Characteristics guaranteed by design, not production tested.

4. Power ON/OFF, measured from 75KHz to 1MHz at Point A-A’ Figure 3 or 4, in accordance with MIL-STD-1553B paragraph

4.5.2.2.2.3.

5. At point A-A’ on Figure 3 or 4, 2.5µS after midpoint crossing of the parity bit of the last word of a 660 µS message.

6. This test is peformed while the Transceiver is reading its own transmission. This condition is called "Wraparound". Standard TTL

loads applied to RX DATA Outputs.
