The SN74ALS240A-1DBRG4 is a high-quality octal buffer and line driver designed by Texas Instruments to specifically cater to the needs of high-speed memory drivers, bus-oriented receivers, and transmitters. This integrated circuit is part of the Advanced Low-Power Schottky (ALS) family, which is renowned for its balance between speed and power consumption.

Key Features

• Logic Type: Octal Buffer/Line Driver
• Number of Channels: 8
• Output Type: 3-State
• Supply Voltage: 4.5V to 5.5V
• Operating Temperature: -40°C to 85°C
• Mounting Type: Surface Mount
• Package / Case: SSOP (Shrink Small Outline Package)

Performance and Quality

The SN74ALS240A-1DBRG4 offers a robust design with a high drive capability, featuring a typical output impedance of 15 ohms. This allows for direct driving of relatively heavy loads while maintaining a fast propagation delay and transition times, which are critical for high-speed operations.

Applications

The versatility of the SN74ALS240A-1DBRG4 makes it suitable for a wide range of applications. It can be used in bus interfacing in microprocessor systems, memory drivers where high speed and low power are necessary, and any digital system where buffer or line driver functionality is needed. Its 3-state outputs also make it ideal for connection to a bus as they can be placed in a high-impedance state, effectively disconnecting the driver from the bus.

Environmental Compliance

As an environmentally conscious product, the SN74ALS240A-1DBRG4 complies with RoHS directives, ensuring that it is free from harmful substances such as lead, mercury, and cadmium. This compliance makes it suitable for use in a variety of markets, including those with strict environmental regulations.
