Logic-Buffers, Drivers, Receivers, Transceivers refer to semiconductor devices that are meant to convert digital signals into analog outputs, or into discrete wiring systems. The HEF40244BP,652 is a quad Tri-State Bi-Directional Logic Buffer designed for use in voltage-level shifting and bus-oriented systems. It is capable of both sinking and sourcing high current, making it an ideal option for applications in mixed voltage-level systems.

The device features an operating voltage range of 2.3V to 6.5V, with a maximum input voltage of 6.5V for switching signals. The output voltage can reach up to 7.5V. It is capable of transferring low electrical current signals between low-voltage systems, up to the levels of the highest-voltage system, while also providing Tri-State control to systems with no common ground.

HEF40244BP,652 has both input and output logic. It uses a “floating”/”toggling” input logic method to allow intermediate voltage level operations. The device utilizes a dual-enable input on each of the four channels, allowing each channel to be separately programmed in order to either drive the output or to be disabled.

When paired with external components and PNP transistors, the device is able to switch between two logic levels, with LED indicators providing visual feedback if an output is high or low. The High speed switching rate of the HEF40244BP,652 lets it switch in less than 1μsec, making it ideal for applications with fast switching speed requirements. The HEF40244BP,652 also features TTL-Compatible inputs, protection against input signal transients, overvoltage and overtemperature protection.

HEF40244BP,652 is suitable for use in many applications, such as clock buffering, logic level switching, system voltage level translation and level shifting, data bus conversion, parallel memory expansion, and bidirectional data transfer. The device is particularly useful in peripherals used in mobile devices and other battery powered circuits, such as cellular phones, PDAs, and laptop computers. Additionally, the HEF40244BP,652 is used in industrial equipment and automotive display applications.

To summarize, the HEF40244BP,652 is a quad Tri-State Bi-Directional Logic Buffer ideal for applications that require voltage-level shifting, fast switching speed, and protection against input signal transients, overvoltage and overtemperature. The device can transfer electrical current signals between low-voltage systems and is capable of both sinking and sourcing high current, making it suitable for use in a wide variety of applications, including mobile devices, industrial equipment, and automotive display applications.
