9328 DM9328 Dual 8-Bit Shift Register
General Description
The ’9328 is a high speed serial storage element providing
16 bits of storage in the form of two 8-bit registers The
multifunctional capability of this device is provided by sever-
al features 1) additional gating is provided at the input to
both shift registers so that the input is easily multiplexed
between two sources 2) the clock of each register may be
provided separately or together 3) both the true and com-
plementary outputs are provided from each 8-bit register
and both registers may be master cleared from a common
input
