VX1120 - Brand New STMicroelectronics IC Chips
-
Description
The VX1120 is a dual J-K Flip-Flop that operates on a negative going transition of the clock pulse. It has independent inputs (J, K, PRESET, CLEAR, and CLOCK) and outputs (Q, Q). The flip-flop is edge sensitive and changes states synchronously. The triggering occurs at the voltage level of the clock and is not dependent on the transition time. The clear and preset functions are independent of the clock and can be activated with a low logic level on the corresponding input. The J and K inputs can change when the clock is in either state without affecting the flip-flop, provided they are in the desired state during the recommended setup and hold times relative to the falling edge of the clock. The VX1120 can tolerate voltages up to 7V, making it suitable for interfacing between 5V systems and 3V systems.
Specifications and features
1. Input voltage level translation from 5V–3V
2. Ideal for low power/low noise 3.3V applications
Application Scenarios
The VX1120 is commonly used in electronic circuits and systems where there is a need for J-K Flip-Flops. It is suitable for applications that require edge sensitive flip-flops and voltage level translation. Some specific scenarios where the VX1120 can be used include:
- Logic circuits
- Data storage systems
- Communication devices
Comparison
The VX1120 has several advantages and disadvantages:
Advantages- Independent inputs and outputs
- Edge sensitive and synchronous
- Tolerates voltages up to 7V
Disadvantages- Requires careful setup and hold times
- Limited to dual flip-flop functionality
