54FCT574
Octal D-Type Flip-Flop with TRI-STATE® Outputs
General Description
The ’FCT574 is an octal flip-flop with a buffered common
Clock (CP) and a buffered common Output Enable (OE). The
information presented to the D inputs is stored in the
flip-flops on the LOW-to-HIGH Clock (CP) transition.
The device is functionally identical to the ’FCT374 except for
the pinouts.
Features
n Inputs and outputs on opposite sides of package
allowing easy interface with microprocessors
n Useful as input or output port for microprocessors
n Functionally identical to ’FCT374
n TRI-STATE outputs for bus-oriented applications
n Output sink capability of 32 mA, source capability of
12 mA
n TTL input and output level compatible
n CMOS power consumption
n Standard Microcircuit Drawing (SMD) 5962-8951301
