Product Description

The HEF40244BT is an integrated circuit that consists of eight non-inverting buffers with 3-state outputs. The device can be used as a buffer or line driver that is necessary for driving bus lines or buffer memory address registers. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. Each output will be in a high-impedance state when the associated output enable (OE) pin is high.

This device has a wide supply voltage range from 3V to 15V, which makes it suitable for interfacing with both TTL and CMOS logic levels without the need for external level shifters. Its high noise immunity and low power consumption are ideal for battery-operated and low-power systems.

The HEF40244BT is packaged in a 20-pin SO package, which is compact and suitable for surface-mounted technology (SMT). The device's operating temperature range of -40°C to +85°C ensures that it can be used in most industrial and commercial temperature ranges, making it a reliable choice for a multitude of applications.

Applications

Due to its versatility, the NXP HEF40244BT can be used in various applications, including:

• Buffering and driving bus lines
• Buffering memory address registers
• Interface between mismatched logic levels
• Industrial control systems
• Data communication systems
