(R) FAST CMOS OCTAL FLIP-FLOP WITH MASTER RESET DESCRIPTION: IDT54/74FCT273 IDT54/74FCT273A IDT54/74FCT273C Integrated Device Technology, Inc. FEATURES: * * * * * * * * * * * * * IDT54/74FCT273 equivalent to FASTTM speed; IDT54/74FCT273A 45% faster than FAST IDT54/74FCT273C 55% faster than FAST Equivalent to FAST output drive over full temperature and voltage supply extremes IOL = 48mA (commercial) and 32mA (military) CMOS power levels (1mW typ. static) TTL input and output level compatible CMOS output level compatible Substantially lower input current levels than FAST (5A max.) Octal D flip-flop with Master Reset JEDEC standard pinout for DIP and LCC Product available in Radiation Tolerant and Radiation Enhanced versions Military product compliant to MIL-STD-883, Class B The IDT54/74FCT273/A/C are octal D flip-flops built using an advanced dual metal CMOS technology. The IDT54/ 74FCT273/A/C have eight edge-triggered D-type flip-flops with individual D inputs and O outputs. The common buffered Clock (CP) and Master Reset (MR) inputs load and reset (clear) all flip-flops simultaneously. The register is fully edge-triggered. The state of each D input, one set-up time before the LOW-to-HIGH clock transition, is transferred to the corresponding flip-flop's O output. All outputs will be forced LOW independently of Clock or Data inputs by a LOW voltage level on the input. The device is useful for applications where the true output only is required and the Clock and Master Reset are common to all storage elements.
