description
SNULSEH. SNNLSGH
The ’LSG73 is a 16»bit shift register and a 16-bit storage
register in a single 24-pin package. A three-state
input/output (SEE/015) port to the shift register allows
serial entrv and/or reading at dalar The storage register
is connected in a parallel data loop with the shift register
and may be asynchronously cleared by taking the store
clear inpul low. The storage register may be parallel
loaded with shift-register data to provide shift-register
status via the parallel outputs. The shift register can be
parallel loaded with the storage-register date upon com-
mand.
A high logic level at the chip»level (a) input disables
both the shirt-register clock and the storage register
clock and places SER/Q‘lE in the high-impedance state.
The store—clear function is not disabled by the chip
select.
Caution must be exercised to prevent false clocking or
either the shift register or the storage register via the
chipselect inputr The shift clock should be low during
the Iow-to-high transition of chip select and the store
clock should be low during the high-to-low transition of
chip select.
SNMLSb74, SN74L$W4
The 'LSG74 is a 16-bit parallel-in, serial—out shift
register. A three-slate input/output lSER/015) pert
provides access for entering a serial data or reading the
shift-register word in a recirculating loop,
The device has ieur basic modes of operation:
1) Hold (do nothing)
2) Write (serially via input/output)
3) Head (serially)
4) Load [parallel via data inputs]
Low-to-high-level changes at the chip select input
should he made only when the clock input is low to pre
vent false clocking.
