The MM74HC273 edge-triggered flip-flop utilizes an advanced silicon-gate CMOS process to implement a D-type flip-flop. They feature high noise immunity, low power consumption and higher speed compared to low power Schottky TTL circuits. The device contains 8 master-slave flip-flops with common clock and common clear. Data on the D input that meets setup and hold time requirements is transferred to the Q output on a low-to-high transition of the clock input. Clearing the input low sets all outputs to the low state. Each output is capable of driving a load equivalent to 10 low-power Schottky TTLs. The MM74HC273 is functionally compatible with the 74LS273. Protect all inputs from electrostatic discharge damage by diode-connecting VCC and ground.
