MC74AC273, MC74ACT273 Octal D Flip-Flop The MC74AC273/74ACT273 has eight edge-triggered D–type flip–flops with individual D inputs and Q 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 setup time before the LOW–to–HIGH clock transition, is transferred to the corresponding flip–flop’s Q output. All outputs will be forced LOW independently of Clock or Data inputs by a LOW voltage level on the MR 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. http://onsemi.com PDIP–20 N SUFFIX CASE 738 20 1 Ideal Buffer for MOS Microprocessor or Memory Eight Edge-Triggered D Flip–Flops Buffered Common Clock Buffered, Asynchronous Master Reset See MC74AC377 for Clock Enable Version See MC74AC373 for Transparent Latch Version See MC74AC374 for 3-State Version Outputs Source/Sink 24 mA ′ACT273 Has TTL Compatible Inputs VCC 20 Q7 19 D7 18 D6 17 Q6 16 Q5 15 D5 14 D4 13 Q4 12 CP 11 20 1 SO–20 DW SUFFIX CASE 751 20 1 TSSOP–20 DT SUFFIX CASE 948E EIAJ–20 M SUFFIX CASE 967 20 1 ORDERING INFORMATION Device MC74AC273N MC74ACT273N MC74AC273DW Package PDIP–20 PDIP–20 SOIC–20 SOIC–20 SOIC–20 SOIC–20 TSSOP–20 Shipping 18 Units/Rail 18 Units/Rail 38 Units/Rail 1000 Tape & Reel 38 Units/Rail 1000 Tape & Reel 75 Units/Rail 1 MR 2 Q0 3 D0 4 D1 5 Q1……
