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

Functional Description
The two 8-bit shift registers have a common clock input (pin
9) and separate clock inputs (pins 10 and 7) The clocking
of each register is controlled by the OR function of the sep-
arate and the common clock input Each register is com-
posed of eight clocked RS master slave flip-flops and a
number of gates The clock OR gate drives the eight clock
inputs of the flip-flops in parallel When the two clock inputs
(the separate and the common) to the OR gate are LOW
the slave latches are steady but data can enter the master
latches via the R and S input During the first LOW-to-HIGH
transition of either or both simultaneously of the two clock
inputs the data inputs (R and S) are inhibited so that a later
change in input data will not affect the master then the now
trapped information in the master is transferred to the slave
When the transfer is complete both the master and the
slave are steady as long as either or both clock inputs re-
main HIGH During the HIGH-to-LOW transition of the last
remaining HIGH clock input the transfer path from master
to slave is inhibited first leaving the slave steady in its pres-
ent state The data inputs (R and S) are enabled so that new
data can enter the master Either of the clock inputs can be
used as clock inhibit inputs by applying a logic HIGH signal
Each 8-bit shift register has a 2-input multiplexer in front of
the serial data input The two data inputs D0 and D1 are
controlled by the data select input (S) following the Boolean
expression
Serial data in SD e SD0 a SD1
An asynchronous master reset is provided which when acti-
vated by a LOW logic level will clear all 16 stages indepen-
dently of any other input signal
