SN74LV374APWR

The SN74LV374APWR is a high-speed, low-voltage, octal D-type flip-flop designed by Texas Instruments. It is part of the 74LV family of logic devices, which are known for their low power consumption and high-speed operation. Here’s a detailed description of its features and specifications:

General Description:

• Type: Octal D-type Flip-Flop
• Package: TSSOP (Thin Shrink Small Outline Package)
• Pin Count: 20 pins
• Supply Voltage: Operates at a low voltage range of 2.0V to 5.5V, making it suitable for battery-powered applications.

Functional Features:

• Data Inputs: The device has eight D-type data inputs (D0 to D7) that capture the input data on the rising edge of the clock signal.
• Clock Input: A single clock input (CLK) is used to synchronize the data capture. The flip-flops change state on the rising edge of the clock.
• Output: The device provides eight complementary outputs (Q0 to Q7 and Q0' to Q7'), allowing for both the normal and inverted output states.
• Enable Control: The flip-flops can be enabled or disabled using the output enable (OE) pin, which allows for tri-state output control.
• Asynchronous Set and Reset: The device features asynchronous set (SET) and reset (RESET) inputs, allowing for immediate control of the output states regardless of the clock.

Electrical Characteristics:

• Propagation Delay: The typical propagation delay from the clock to the output is low, typically around 4.5 ns at 5V, ensuring fast operation.
• Power Consumption: The device is designed for low power consumption, making it ideal for portable and battery-operated devices.
• Input and Output Voltage Levels: The input high voltage (VIH) and input low voltage (VIL) levels are compatible with TTL logic levels, ensuring interoperability with other logic families.
