DM74S174 DM74S175 Hex/Quad D Flip-Flop with Clear August 1986 Revised April 2000 DM74S174 DM74S175 Hex/Quad D Flip-Flop with Clear General Description These positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop lo gic. All h ave a d irect cle ar input, and the quad (DM74S175) versions feature complementary outputs from each flip-flop. Information at the D inputs meeting the setup time requirements 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 th e H IGH or LOW l evel, th e D i nput si gnal has no effect at the output. Features s DM74S174 contain six flip-flops with single-rail outputs. s DM74S175 con tain fo ur fl ip-flops w ith do uble-rail outputs. s Buffered clock and direct clear inputs s Individual data input to each flip-flop s Applications include: Buffer/storage registers Shift registers Pattern generators s Typical clock frequency 110 MHz s Typical power dissipation per flip-flop 75mW Ordering Code: Order Number DM74S174N DM74S175N Package Number N16E N16E Package Description 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Connection Diagrams DM74S174 DM74S175 © 2000 Fairchild Semiconductor Corporation DS006472 www.fairchildsemi.com h...
