description
These monolithic positive-edge-triggered D-type
flip-flops have a direct clear (CLR) input. The
’HC175 feature complementary outputs from
each flip-flop.
Information at the data (D) inputs meeting the
setup time requirements is transferred to the
outputs on the positive-going edge of the clock
(CLK) pulse. Clock triggering occurs at a
particular voltage level and is not directly related
to the transition time of the positive-going edge of
CLK. When CLK is at either the high or low level,
the D input has no effect at the output.
The SN54HC175 is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74HC175 is characterized for
operation from –40°C to 85°C.
