Product Overview: SN74LV244ATDWR from Texas Instruments

The SN74LV244ATDWR is a high-performance, octal buffer/driver from Texas Instruments, designed to operate with a wide voltage range of 2V to 5.5V. This device is particularly suitable for driving bus lines or buffer memory address registers due to its high-drive outputs, which can sink up to 24 mA and source up to 24 mA. It belongs to the 74LV family, which is known for its low-voltage operation and low power consumption, making it ideal for use in battery-powered and portable applications.

The SN74LV244ATDWR comes in a wide-body SOIC (Small Outline Integrated Circuit) package with 20 pins, ensuring a compact footprint while providing robust connection points for printed circuit boards (PCBs). The device features two separate enable inputs (1G and 2G) which control four buffers each, allowing for greater flexibility in the control of data flow through the device.

With its 3-state outputs, the SN74LV244ATDWR can be placed in a high-impedance state, effectively disconnecting the output from the circuit, which is a crucial feature for implementing bus-oriented systems. This characteristic also allows for the direct connection of multiple outputs to a bus, providing a wired-OR configuration.

Key features of the SN74LV244ATDWR include:

• Wide Operating Voltage Range: 2V to 5.5V
• High-Drive Outputs: -24 mA IOL, 24 mA IOH
• Low Power Consumption: ICC of 20 µA Max
• Multiple Enable Inputs for Flexible Control
• 3-State Outputs for Bus Aggregation
• Wide-Body SOIC-20 Package for Easy PCB Integration

Whether you're designing microprocessor or microcomputer systems, the SN74LV244ATDWR is engineered to provide reliable buffer and driver capabilities with the low-power requirements and high noise immunity needed in modern electronic applications. Its compatibility with 5V TTL logic and ability to interface with the high-speed properties of CMOS makes it a versatile choice for mixed-technology environments.

Overall, the SN74LV244ATDWR from Texas Instruments is a testament to their commitment to providing high-quality, reliable components for a wide range of electronic applications, from consumer electronics to industrial automation systems.
