Product Overview: 74ALS240AN by NXP

The 74ALS240AN is a high-quality integrated circuit manufactured by NXP Semiconductors, a leader in the electronics industry. This particular device is part of the Advanced Low-Power Schottky (ALS) logic family, which is renowned for combining low power consumption with high-speed operation. The 74ALS240AN is an octal buffer and line driver designed to interface with 8-bit data buses and provide bidirectional drive capabilities with high-current output for driving heavy loads.

Key Features

• Logic Type: Octal Buffer/Line Driver
• Number of Channels: 8
• Output Type: 3-State
• Supply Voltage Range: 4.5V to 5.5V
• Operating Temperature Range: -40°C to +85°C
• Package: DIP-20 (Dual In-line Package)

The 74ALS240AN features two sets of eight buffers with 3-state outputs, which can be independently controlled. This offers flexibility, allowing the device to be used as either a single 8-bit buffer or as two separate 4-bit buffers. The 3-state outputs ensure that multiple devices can be connected to a data bus without the risk of bus contention.
