Notes:

1. VCC = +15Volts ±0.75V, VEE = -15Volts ±0.75V, VIL = +5Volts ±0.5V, TC = -55°C to +125°C, unless otherwise

specified.

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 4, in accordance with MIL-STD-1553B

paragraph 4.5.2.2.2.3.

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

6. Receiver skew is defined as the time from the rising edge of RX DATA OUT to the rising edge of RX DATA OUT

minus 500 nS, with a sine wave input of 3 VPK-PK at 1MHz driven into Pt. B-B’ of Figure 4 or 2.1 VPK-PK at 1MHz

driven into Pt. B-B’ of Figure 3. The specification maximum is guaranteed for TA = 25°C only. Standard TTL loads

applied to RX DATA Outputs.

7. 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.
