MOStechnology.Ithas thesame highspeedper-
formance of LSTTL combined with true CMOS low
powerconsumption.
Thisdevices comesin a16-pin package and consist
of an 8-bit storage latch feeding a parallel-in, serial-
out 8-bitshift register. Both the storageregister and
shift register have positive-edge triggered clocks.
The shift register also hasdirect load (fromstorage)
and clearinputs.
All inputs are equipped with protection circuits
against static discharge and transient voltage ex-
cess.
