MC74AC574, MC74ACT574 Octal D Flip-Flop with 3-State Outputs The MC74AC574/74ACT574 is a high–speed, low power 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 MC74AC574/74ACT574 is functionally identical to the MC74AC374/74ACT374 except for the pinouts. http://onsemi.com PDIP–20 N SUFFIX CASE 738 20 1 Inputs and Outputs on Opposite Sides of Package Allowing Easy Interface with Microprocessors Useful as Input or Output Port for Microprocessors Functionally Identical to MC74AC374/74ACT374 3-State Outputs for Bus-Oriented Applications Outputs Source/Sink 24 mA ′ACT574 Has TTL Compatible Inputs VCC 20 O0 19 O1 18 O2 17 O3 16 O4 15 O5 14 O6 13 O7 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 1 OE 2 D0 3 D1 4 D2 5 D3 6 D4 7 D5 8 D6 9 D7 10 GND MC74AC574N MC74ACT574N MC74AC574DW MC74AC574DWR2 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 Figure 1.
