Logic - Gates and Inverters

The SN74ALVC00DR is a dual positive-edge triggered D-type flip-flop with 3-state outputs. It is capable of driving up to 15 discrete output stages. It is available in both through-hole and surface-mount packages. The ALVC00DR is a part of the family of SN74ALVC series digital devices from Texas Instruments. The device is a high-performance digital logic device that can be used in various logic design applications. In this article, we will explore the application field and working principle of the SN74ALVC00DR.

Application Field

The SN74ALVC00DR has a wide range of applications. It can be used in a variety of digital logic designs, such as general purpose logic applications, interface and system timing, input/output multiplexers and flip-flops, parallel-to-serial converters, sequential logic, and register addressing. It is also suitable for low-power and high-speed applications, such as portable, hand-held, and battery-powered applications.

The SN74ALVC00DR is also used in many industrial and communications applications such as ATE, avionics, industrial process controls bussing, telecommunications, and data acquisition systems. The device is useful for applications operating at low clock frequencies, but is especially useful for applications that operate at high clock frequencies such as 38.4Mbps serial data transmission. The device also has a wide range of power supply voltage options, so it can be used in a variety of applications from 3V to 5.5V.

Working Principle

The SN74ALVC00DR is a dual positive-edge triggered D-type flip-flop with 3-state outputs. The device consists of two logic portions, each containing a single D-type flip-flop and a 3-state output buffer. The flip-flops are triggered by the rising edge of the clock input (CLK) and data is transferred on the positive transition of the clock input. Data is transferred from the inputs (D1, D2) to the outputs (Q1, Q2) when the clock input is high.

The output buffers are controlled by the OE (Output Enable) input. The outputs are enabled when the OE is low, and disabled when the OE is high. The device also includes asynchronous Set and Reset inputs, which allow the flip-flops to be reset independently of the clock input. When the Reset inputs are low, both flip-flops are reset and the outputs will be in a low (logic 0) state.

The device also includes an internal output control logic which enables the output buffer to be enabled for a period after the clock rising edge, but before the output data is valid. This output control logic ensures that glitches are not present on the device outputs prior to valid data being present on the outputs. This feature, along with the low noise generation, makes the SN74ALVC00DR ideal for high-speed applications.

Conclusion

The SN74ALVC00DR is a high-performance digital logic device that can be used for a wide range of applications, from low-power and high-speed processing, to portable, hand-held and battery-powered applications. It is a dual positive-edge triggered D-type flip-flop with 3-state outputs, and includes asynchronous Set and Reset inputs as well as output control logic. The device is especially effective in high-speed applications due to its low noise generation and output control logic.
