Functional Description
The ’F534 consists of eight edge-triggered flip-flops with in-
dividual D-type inputs and TRI-STATE complementary out-
puts The buffered clock and buffered Output Enable are
common to all flip-flops The eight flip-flops will store the
state of their individual D inputs that meet the setup and
hold times requirements on the LOW-to-HIGH clock (CP)
transition With the Output Enable (OE) LOW the contents
of the eight flip-flops are available at the outputs When the
OE is HIGH the outputs go to the high impedance state
Operation of the OE input does not affect the state of the
flip-flops
