HEX D FLIP-FLOP
The LSTTL / MSI SN54 / 74LS174 is a high speed Hex D Flip-Flop. The
device is used primarily as a 6-bit edge-triggered storage register. The
information on the D inputs is transferred to storage during the LOW to HIGH
clock transition. The device has a Master Reset to simultaneously clear all
flip-flops. The LS174 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
• Asynchronous Common Reset
• Input Clamp Diodes Limit High Speed Termination Effects
