DESCRIPTION
The 74F674 is a 16-bit shift register with serial and parallel load
capability and serial output. A single pin serves alternately as an
input for serial entry or as a 3-State serial output. In the serial out
mode the data recirculates in the register. Chip Select, Read/Write
and Mode inputs provide control flexibility. The 74F674 operates in
one of four modes, as indicated in the Function table.
Hold
: A High signal on the Chip Select (CS) input prevents clocking
and forces the Serial Input/Output (SI/O) 3-State buffer into the high
impedance state.
Serial load
: Data present on the SI/O pin shifts into the register on
the falling edge of CP. Data enters the Q0 position and shifts toward
Q15 on successive clocks.
Serial output
: The SI/O 3-State buffer is active and the register
contents are shifted out from Q15 and simultaneously shifted back
into Q0.
Parallel load
: Data present on D0–D15 is entered into the register
on the falling edge of CP. The SI/O 3-State buffer is active and
represents the Q15 output. To prevent false clocking, CP must be
Low during a Low-to-High transition of CS.
