The SN74F657DWRE4 is an integrated circuit (IC) component developed by Texas Instruments. It belongs to the SN74F series of logic devices and is specifically designed for digital data storage and manipulation applications.
The IC offers several key features that make it suitable for a wide range of electronic systems. Firstly, it is a 10-bit universal bus transceiver with three-state outputs, meaning it can both transmit and receive data on a bidirectional bus. This capability enables the IC to interface with various components, such as microcontrollers, memory devices, and other digital circuits.
The SN74F657DWRE4 utilizes TTL (Transistor-Transistor Logic) technology, which provides fast switching speeds and low power consumption, making it ideal for high-performance applications. Its operating voltage range spans from 4.5V to 5.5V, making it compatible with standard power supplies commonly used in electronic systems.
Another notable feature of this IC is its 3-state outputs, which allow it to effectively isolate the bus from the rest of the system when disabled. This feature enables multiple devices to share the same bus without interfering with each other, ensuring efficient data transfer and reducing contention.
The SN74F657DWRE4 also includes active bus-hold circuitry, which maintains the last valid data state on the bus when no device is actively driving it. This feature prevents bus-corruption issues that may arise due to floating inputs and enhances system reliability
