DESCRIPTION
The 74LVC273 is a low-voltage Si-gate CMOS device,
superior to most advanced CMOS compatible TTL
families.
The 74LVC273 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.
