Hex/Quadruple D-Type Flip-Flops with Clear
These monolithic, positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop
logic. All have a direct clear input, and the ‘175, ‘LS175, and ‘S175 feature complementary outputs
from each flip-flop.
Information at the D inputs meeting the setup time requirements is transferred to the Q outputs on the
positive-going edge of the clock pulse. Clock triggering occurs at a particular voltage level and is not
directly related to the transition time of the positive-going pulse. When the clock input is at either the
high or low level, the D input signal has no effect at the output.

Manufactured Components
Rochester branded components are
manufactured using either die/wafers
purchased from the original suppliers
or Rochester wafers recreated from the
original IP. All recreations are done with
the approval of the OCM.
Parts are tested using original factory
test programs or Rochester developed
test solutions to guarantee product
meets or exceeds the OCM data sheet.
