54FCT574

54FCT574 Octal D-Type Flip-Flop with TRI-STATE Outputs October 1999 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 54FCT574DMQB 54FCT574FMQB 54FCT574LMQB Package Number J20A W20A E20A Connection Diagrams Pin Assignment for DIP and Flatpak Package Description 20-Lead Ceramic Dual-In-Line 20-Lead Cerpack 20-Lead Ceramic Leadless Chip Carrier, Type C Pin Descriptions Pin Names D0– D7 CP OE O0– O7 Description Data Inputs Clock Pulse Input (Active Rising Edge) TRI-STATE Output Enable Input (Active LOW) TRI-STATE Outputs DS100966-1 Pin Assignment for LCC DS100966-2 TRI-STATE® is a registered trademark of National Semiconductor Corporation. © 1999 National Semiconductor Corporation DS100966 www.national.com 54...
