TABLE 6. 7846 TIMING CHARACTERISTICS1,2,3,4
(V
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.
