Part Number: 74LS175, DM74LS175, 74175 Function : Hex/Quad D-Type Flip-Flops with Clear Package: DIP, SOP, SOIC 16 Pin Type Manufacturer: Fairchild Semiconductor Pinout
These positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic. All have a direct clear input, and the quad (175) versions feature complementary outputs from each flip-flop. Information at the D inputs meeting the setup time require ments is transferred to the Q outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going pulse. When the clock input is at either the HIGH or LOW level, the D input signal has no effect at the output. Logic Diagrams 1. 74LS174 contains six flip-flops with single-rail outputs 2. 74LS175 contains four flip-flops with double-rail outputs 3. Buffered clock and direct clear inputs 4. Individual data input to each flip-flop 5. Applications include: (1) Buffer/storage registers (2) Shift registers (3 )Pattern generators 6. Typical clock frequency 40 MHz 7. Typical power dissipation per flip-flop 14 mW 74LS175 Datasheet |
