Features, Applications |
The is a high-speed, low-power octal D-type flip-flop featuring separate D-type inputs for each flip-flop and TRI-STATE outputs for bus-oriented applications. A buffered Clock (CP) and Output Enable (OE) are common to all flip-flops. Outputs source/sink 24 mA See '273 for reset version See '377 for clock enable version See '373 for transparent latch version See '574 for broadside pinout version See '564 for broadside pinout version with inverted outputs n 'ACT374 has TTL-compatible inputs n Standard Military Drawing (SMD) 'ACT374: 5962-87631 Featuresn ICC and IOZ reduced 50% n Buffered positive edge-triggered clock n TRI-STATE outputs for bus-oriented applications DescriptionClock Pulse Input TRI-STATE Output Enable Input TRI-STATE Outputs TRI-STATE is a registered trademark of National Semiconductor Corporation. FACT is a registered trademark of Fairchild Semiconductor Corporation. The 'AC/'ACT374 consists of eight edge-triggered flip-flops with individual 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 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.
