Product data sheet
1. General description
The 74HC173; 74HCT173 is a quad positive-edge triggered D-type flip-flop. The device
features clock (CP), master reset (MR), two input enable (E1, E2) and two output enable
(OE1, OE2) inputs. When the input enables are LOW, the outputs Qn will assume the
state of their corresponding Dn inputs that meet the set-up and hold time requirements on
the LOW-to-HIGH clock (CP) transition. A HIGH on either input enable will cause the
device to go into a hold mode, outputs hold their previous state independently of clock and
data inputs. A HIGH on MR forces the outputs LOW independently of clock and data
inputs. A HIGH on either output enable pin causes the outputs to assume a
high-impedance OFF-state. Operation of the output enable inputs does not affect the state
of the flip-flops. Inputs include clamp diodes. This enables the use of current limiting
resistors to interface inputs to voltages in excess of VCC.
