Table 1: Order Codes
These devices have four modes (HOLD, SHIFT
LEFT, SHIFT RIGHT and LOAD DATA). Each
mode is chosen by two function select inputs (S0,
S1) as shown in the Truth Table.
When one or both enable inputs, (G1, G2) are
high, the eight input/output terminals are in the
high
operation or clearing of the register is not affected.
Clear function is asynchronous to clock.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
