DESCRIPTION
The 74LV273 is a low-voltage Si-gate CMOS device and is pin and
function compatible with the 74HC/HCT273.
The 74LV273 has eight edge-triggered , D-type flip-flops with
individual D inputs and Q outputs. The common clock (CP) and
master reset (MR) inputs load and reset (clear) all flip-flops
simultaneously. The state of each D input, one set-up time before
the LOW-to-HIGH clock transition, is transferred to the
corresponding output (Qn) of the flip-flop.
All outputs will be forced LOW independently of clock or data inputs
by a LOW voltage level on the MR input.
The device is useful for applications where the true output only is
required and the clock and master reset are common to all storage
elements.
