Notes:

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

3. Characteristics guaranteed by design, not production tested.

4. Power ON/OFF, measured 1MHz at Point A-A’ Figure 4.

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

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.
