Octal D-Type Flip-Flop with TRI-STATE Outputs
General Description
The ’F374 is a high-speed low-power octal D-type flip-flop
featuring separate D-type inputs for each flip-flop and
TRI-STATE outputs for bus-oriented applications A buff-
ered Clock (CP) and Output Enable (OE) are common to all
flip-flops
Features
Y Edge-triggered D-type inputs
Y Buffered positive edge-triggered clock
Y TRI-STATE outputs for bus-oriented applications
Y Guaranteed 4000V minimum ESD protection

Functional Description
The ’F374 consists of eight edge-triggered flip-flops with in-
dividual D-type inputs and TRI-STATE true outputs 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 time re-
quirements 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 affected the state of the flip-flops
