NOTES

1Temperature range (T

MIN to TMAX); 0°C to +70°C.

2Sample tested at +25

°C to ensure compliance.

3TTL input values are 0 to 3 volts, with input rise/fall times

≤3 ns, measured between the 10% and 90% points. Timing reference points at 50% for inputs and

outputs. See timing notes in Figure 1.

4This includes effects due to clock and data feedthrough.

Specifications subject to change without notice.
