Overview
DM74174 Hex/Quad D-Type Flip-Flop with Clear September 1986 Revised February 2000 DM74174 Hex/Quad D-Type Flip-Flop with Clear General Description These positive-edge triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic.
All have a direct clear input.
Information at the D inputs meeting the setup and hold 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 the HIGH or LOW level, the D input signal has no effect at the output.
Features s Contains six flip-flops with single-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 40 MHz s Typical power dissipation per flip-flop 38 mW Ordering Code: Order Number DM74174 Package Number N16E Package Description 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.
