TABLE 6. 7846A TIMING CHARACTERISTICS1,2,3,4

DD = +14.25V TO 15.75V; VSS = -14.25V TO -15.75V; VCC = 4.75 TO 5.25V; UNLESS OTHERWISE SPECIFIED)

1. Guaranteed by design. All input control signals are specified with t

R = tF = 5ns (10% to 90% of +5V) and timed from a voltage

level of 1.6V.

2. t

6 is measured with the load circuits of Figure 1 and defined as the time required for an output to cross 0.8V or 2.4V.

3. t

7 is defined as the time required for an output to change 0.5V when loaded with the circuits of Figure 2. Specifications subject to

change without notice.

4. See Figure 3 on page 7.
