description
The ’HC166 parallel-in or serial-in, serial-out
registers feature gated clock (CLK, CLK INH)
inputs and an overriding clear (CLR) input. The
parallel-in or serial-in modes are established by
the shift/load (SH/LD) input. When high, SH/LD
enables the serial (SER) data input and couples
the eight flip-flops for serial shifting with each
clock (CLK) pulse. When low, the parallel
(broadside) data inputs are enabled, and
synchronous loading occurs on the next clock
pulse. During parallel loading, serial data flow is
inhibited. Clocking is accomplished on the
low-to-high-level edge of CLK through a 2-input
positive-NOR gate permitting one input to be used
as a clock-enable or clock-inhibit function. Holding
either CLK or CLK INH high inhibits clocking;
holding either low enables the other clock input.
This allows the system clock to be free running,
and the register can be stopped on command with
the other clock input. CLK INH should be changed
to the high level only when CLK is high. CLR
overrides all other inputs, including CLK, and
resets all flip-flops to zero.
The SN54HC166 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C. The
SN74HC166 is characterized for operation from –40
°
C to 85
°
C.
