OCTAL D-TYPE FLIP-FLOP WITH 3-STATE OUTPUTS The MC74AC534/74ACT534 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 bus oriented applications. A buffered Clock (CP) and Output Enable (OE) are common to all flip flops. The ′AC/ACT534 is the same as the ′AC/ACT374 except that the outputs are inverted. • Edge-Triggered D-Type Inputs • Buffered Positive Edge-Triggered Clock • 3-State Outputs for Bus Oriented Applications VCC O7 D7 D6 O6 O5 D5 D4 O4 CP 20 19 18 17 16 15 14 13 12 11 1 2 3 4 5 6 7 8 9 10 OE O0 D0 D1 O1 O2 D2 D3 O3 GND N SUFFIX CASE 738-03 PLASTIC DW SUFFIX CASE 751D-04 PLASTIC PIN NAMES D0–D7 CP OE O0–O7 Data Inputs Clock Pulse Input 3-State Output Enable Input Complementary 3-State Outputs LOGIC SYMBOL 3 11 1 5-1 7 8 13 14 17 18 D0 D1 D2 D3 D4 D5 D6 D7 CP OE O0 O1 O2 O3 O4 O5 O6 O7 2 FACT DATA 4 5 6 9 12 15 16 19 MC74AC534 MC74ACT534 FUNCTIONAL DESCRIPTION The MC74AC534/74ACT534 consists of eight edge-triggered 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 times 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.
