NOTES:
1. Maximum limits of minimum characteristics are the values above which all devices function.
2. Typical values are for T
A
= 25
o
C and nominal voltages.
3. Clock frequency and pulse width are given for systems using the internal clock option of the CDP1855. Clock frequency equals shift
frequency for systems not using the internal clock option.
4. Shift period for cascading of devices is increased by an amount equal to the C.I. to C.O. Propagation Delay for each device added.
