Names Description U.L. Input I IH/IIL HIGH/LOW Output I OH/IOL D0 –D7 Data Inputs 1.0/1.0 20 mA/b0.6 mA CP Clock Pulse Input (Active Rising Edge) 1.0/1.0 20 mA/b0.6 mA OE TRI-STATE Output Enable Input (Active LOW) 1.0/1.0 20 mA/b0.6 mA O0 –O7 TRI-STATE Outputs 150/40 (33.3) b3 mA/24 mA (20 mA) Functional Description The ’F374 consists of eight edge-triggered flip-flops with in- dividual D-type inputs and TRI-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 re- quirements 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 affected the state of the flip-flops.
