BUY M74HC74B1R https://www.utsource.net/itm/p/837940.html
Low-Voltage Adjustable Precision Shunt Regulator 3-TO-92 -40 to 85
Description: The M74HC74B1R is a dual D-type flip-flop with reset. It has two independent D-type flip-flops with complementary outputs. The flip-flops are edge-triggered and are clocked by the positive-going transition of the clock (CP) input. The data (D) input is accepted by the flip-flop on the positive-going transition of the clock pulse. Features: High speed: tPD = 8.0 ns (typ.) at VCC = 6.0 V Low power dissipation: ICC = 4.0 μA (max.) at Ta = 25°C High noise immunity: VNIH = VNIL = 28% VCC (min.) Balanced propagation delays: tPLH tPHL Symmetrical output impedance: |IOH| = IOL = 4 mA (min.) Wide operating voltage range: VCC (opr) = 2.0 to 6.0 V Pin and function compatible with 74HC74 Applications: Frequency division Pulse generation Pulse shaping Timing Data storage (For reference only)
