Additional Details

The TC74VHCT244AF(BEKF features eight independent buffers/line drivers, each with a non-inverting 3-state output. The 3-state outputs allow the device to be connected to a bus without interfering with other devices on the bus. When the output enable (OE) input is high, the outputs are in a high-impedance state, effectively disconnecting the device from the bus.

The TTL compatible inputs allow the device to be directly interfaced with TTL logic circuits without the need for external level translation. The high-speed operation makes it suitable for applications where fast data transfer is required.

The device is commonly used in memory addressing applications to drive the address lines of memory devices. It is also used for data bus isolation to prevent one part of a system from interfering with another. The high output drive capability allows it to drive multiple loads, making it suitable for driving clock signals to multiple devices.

The TC74VHCT244AF(BEKF is available in a SOP20 package, which is a small and compact package suitable for surface mount technology (SMT). The operating voltage range of 4.5V to 5.5V allows the device to be used in a variety of applications.
