74LS174 DIP Hex D-Type Flip-Flop With Common Clear

The 74LS174 is a high speed TTL integrated circuit containing six independent D-type flip-flops with a common clock and a common clear input. This device is designed for use in high density digital systems where multiple bits of data need to be stored or synchronized simultaneously. Information at the D inputs that meets the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock pulse.

This IC is particularly effective for buffer registers, shift registers, and pattern generators. It features a master reset (clear) input that is asynchronous; when pulled low, it immediately sets all six outputs to a low logic level regardless of the clock or data states. The use of low power Schottky technology ensures high speed data transfer while maintaining low power consumption, making it a standard choice for data latching in microprocessor and communication bus interfaces.
