100353
Low Power 8-Bit Register
General Description
The 100353 contains eight D-type edge triggered, master/
slave flip-flops with individual inputs (D
n
), true outputs (Q
n
),
a clock input (CP), and a common clock enable pin (CEN).
Data enters the master when CP is LOW and transfers to the
slave when CP goes HIGH. When the CEN input goes HIGH
it overrides all other inputs, disables the clock, and the Q out-
puts maintain the last state.
The 100353 output drivers are designed to drive 50
termi-
nation to -2.0V. All inputs have 50 k
pull-down resistors.

Note 3: F100K 300 Series cold temperature testing is performed by temperature soaking (to guarantee junction temperature equals -55C), then testing immediately
without allowing for the junction temperature to stabilize due to heat dissipation after power-up. This provides "cold start" specs which can be considered a worst case
condition at cold temperatures.
Note 4: Screen tested 100% on each device at -55C, +25C, and +125C, Subgroups 1, 2, 3, 7, and 8.
Note 5: Sample tested (Method 5005, Table I) on each manufactured lot at -55C, +25C, and +125C, Subgroups A1, 2, 3, 7, and 8.

Note 7: F100K 300 Series cold temperature testing is performed by temperature soaking (to guarantee junction temperature equals -55C), then testing immediately
after power-up. This provides "cold start" specs which can be considered a worst case condition at cold temperatures.
Note 8: Screen tested 100% on each device at +25C temperature only, Subgroup A9.
Note 9: Sample tested (Method 5005, Table I) on each manufactured lot at +25C, Subgroup A9, and at +125C and -55C, temperatures, Subgroups A10 and A11.
Note 10: Not tested at +25C, +125C, and -55C temperature (design characterization data).
Note 11: The propagation delay specified is for single output switching. Delays may vary up to 300 ps with multiple outputs switching.
