QUAD D FLIP-FLOP
The LSTTL / MSI SN54 / 74LS175 is a high speed Quad D Flip-Flop. The
device is useful for general flip-flop requirements where clock and clear inputs
are common. The information on the D inputs is stored during the LOW to
HIGH clock transition. Both true and complemented outputs of each flip-flop
are provided. A Master Reset input resets all flip-flops, independent of the
Clock or D inputs, when LOW.
The LS175 is fabricated with the Schottky barrier diode process for high
speed and is completely compatible with all Motorola TTL families.
• Edge-Triggered D-Type Inputs
• Buffered-Positive Edge-Triggered Clock
• Clock to Output Delays of 30 ns
• Asynchronous Common Reset
• True and Complement Output
• Input Clamp Diodes Limit High Speed Termination Effects
