Power logic 8-bit shift register; open-drain outputs
10. Dynamic characteristics
[1] Typical values are measured at T
amb
= 25 C and V
CC
= 5.0 V.
[2] t
pd
is the same as t
PLH
and t
PHL
.
[3] This is the maximum serial clock frequency assuming cascaded operation where serial data is passed from one stage to a second
stage. The clock period allows for SHCP → Q7S propagation delay and setup time plus some timing margin.
[4] Technique should limit T
j
T
amb
to 10 C maximum.
[5] These parameters are measured with voltage-sensing contacts separate from the current-carrying contacts.
