Flip Flops

The Texas Instruments SN74LS273DWR is a high-performance, low-power, 8-bit wide transparent latch made with advanced CMOS technology. It is designed to provide reliable performance in a wide range of applications. Here's a description of the model, its features, and applications:

Description:

The SN74LS273DWR is a member of the 74LS series of logic devices from Texas Instruments. It is an 8-bit wide transparent latch that allows data to pass through from the input to the output when the control signal is active. The device is available in a small-outline, wide-body (SOIC) package, making it suitable for use in space-constrained applications.

Features:

1. 8-bit Wide Latch: The SN74LS273DWR provides an 8-bit wide transparent latch, allowing it to store and transfer 8 bits of data simultaneously.
2. Low Power Consumption: The device is designed for low power consumption, making it suitable for battery-powered or energy-sensitive applications.
3. High-Speed Operation: The SN74LS273DWR offers high-speed performance, with a propagation delay of typically 3.3 ns (typical) and a rise and fall time of 2.4 ns (typical).
4. Positive Edge Triggered: The device is positive edge triggered, meaning that the output is updated on the rising edge of the control signal.
5. Wide Operating Voltage Range: The SN74LS273DWR operates over a wide voltage range of 2.0V to 6.0V, making it suitable for various power supply requirements.
6. High Noise Immunity: The device offers high noise immunity, ensuring reliable operation in noisy environments.
7. Small Package Size: The SOIC package is compact, making it suitable for use in space-constrained applications.

Applications:

1. Data Storage and Transfer: The SN74LS273DWR can be used to store and transfer data in digital systems, such as microcontroller-based applications.
2. Buffering: It can be used as a buffer to isolate different sections of a digital circuit or to provide additional current drive for downstream logic.
3. Level Shifting: The device can be used for level shifting between different voltage domains in a digital system.
4. Register Applications: The SN74LS273DWR can be used in register applications, where data needs to be temporarily stored and then transferred to another part of the system.
5. Signal Conditioning: It can be used for signal conditioning, such as debouncing or synchronizing signals in digital systems.
6. Test and Measurement Equipment: The device can be used in test and measurement equipment, where high-speed and low-power performance are required.

In summary, the Texas Instruments SN74LS273DWR is a versatile, high-speed, low-power 8-bit transparent latch that can be used in a wide range of digital applications, including data storage and transfer, buffering, level shifting, and signal conditioning. Its compact package size and wide operating voltage range make it suitable for both space-constrained and energy-sensitive applications.
