| MC74AC374 MC74ACT374 Octal D Type Flip Flop with 3 State Outputs The MC74AC374/74ACT374 is a high-speed, low-power octal D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-state outputs for busoriented applications. A buffered Clock (CP) and Output Enable (OE) are common to all flip-flops. * * * * * * * * * Buffered Positive Edge-Triggered Clock 3-State Outputs for Bus-Oriented Applications Outputs Source/Sink 24 mA See MC74AC273 for Reset Version See MC74AC377 for Clock Enable Version See MC74AC373 for Transparent Latch Version See MC74AC574 for Broadside Pinout Version See MC74AC564 for Broadside Pinout Version with Inverted Outputs ACT374 Has TTL Compatible Inputs VCC 20 O7 19 D7 18 D6 17 O6 16 O5 15 D5 14 D4 13 O4 12 CP 11 DW SUFFIX CASE 751D-04 PLASTIC OCTAL D-TYPE FLIP-FLOP WITH 3-STATE OUTPUTS N SUFFIX CASE 738-03 PLASTIC 1 OE 2 O0 3 D0 4 D1 5 O1 6 O2 7 D2 8 D3 9 O3 10 GND LOGIC SYMBOL PIN NAMES D0-D7 CP OE O0-O7 Data Inputs Clock Pulse Input 3-State Output Enable Input 3-State Outputs CP OE D0 D1 D2 D3 D4 D5 D6 D7 O0 O1 O2 O3 O4 O5 O6 O7 TRUTH TABLE Inputs Dn H L X CP OE L L H Outputs On H L Z X H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial Z = High Impedance = LOW-to-HIGH Transition FACT DATA 5-1 MC74AC374 MC74ACT374 FUNCTIONAL DESCRIPTION The MC74AC374/74ACT374 consists of eight edgetriggered flip-flops with individual D-type inputs and 3-state true outputs. The buffered clock and buffered Output Enable are common to all flip-flops. The eight flip-flops will store the state of their individual D inputs that meet the setup and hold time requirements on the LOW-to-HIGH Clock (CP) transition. With the Output Enable (OE) LOW, the contents of the eight flip-flops are available at the outputs. When the OE is HIGH, the outputs go to the high impedance state. Operation of the OE input does not affect the state of the flip-flops.
