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
Description
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.
