TECHNICAL DATA
Octal D Flip-Flop with Common Clock and Reset
The KK74LV273 is a low-voltage Si-gate CMOS device and is pin and function compatible with the 74HC/HCT273. The KK74LV273 has eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs. The common clock (CP) and master reset (MR) inputs load and reset (clear) all flip-flops simultaneously. The state of each D input, one set-up time before the LOW-to-HIGH clock transition, is transferred to the corresponding output (Qn) of the flip-flop. All outputs will be forced LOW independently of clock or data inputs by a LOW voltage level on the MR input. The device is useful for applications where the true output only is required and the clock and master reset are common to all storage elements. • Output voltage levels are compatible with input levels of CMOS, NMOS and TTL ICS • Supply voltage range: 1.2 to 5.5 V • Low input current: 1.0 µА; 0.1 µА at Т = 25 °С • High Noise Immunity Characteristic of CMOS Devices

This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
