1 / 7 page 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 Ordering Code Military Package Number Package Description 54FCT574DMQB J20A 20-Lead Ceramic Dual-In-Line 54FCT574FMQB W20A 20-Lead Cerpack 54FCT574LMQB E20A 20-Lead Ceramic Leadless Chip Carrier, Type C Connection Diagrams Pin Descriptions Pin Description Names D 0–D7 Data Inputs CP Clock Pulse Input (Active Rising Edge) OE TRI-STATE Output Enable Input (Active LOW) O 0–O7 TRI-STATE Outputs TRI-STATE® is a registered trademark of National Semiconductor Corporation.
