STMicroelectronics 74VHCT244ATTR Octal Buffer/Line Driver

The 74VHCT244ATTR is a high-speed CMOS octal buffer and line driver designed to interface with 5V systems. Manufactured by STMicroelectronics, this integrated circuit is part of their VHCT family, offering advanced performance in signal buffering with the ability to drive bus lines or buffer memory address registers. Its robust design ensures that it is suitable for a wide range of applications, from industrial to commercial, and it is especially well-suited for driving capacitive loads with its high drive current capability.

This device features eight non-inverting buffers with 3-state outputs, which makes it ideal for use in applications where output enable controls are necessary. This allows the device to effectively control data flow on a bus or an interface, ensuring that multiple devices can communicate without interference. The 3-state outputs also mean that multiple 74VHCT244ATTR devices can be connected to the same bus without conflict.

With a supply voltage range of 4.5V to 5.5V, the 74VHCT244ATTR is optimized for low power consumption while maintaining high speed operation. It is capable of operating at speeds comparable to LSTTL with significantly lower power consumption. The high noise immunity and low power dissipation of this device make it a practical choice for portable and battery-operated equipment.

The 74VHCT244ATTR comes in a TSSOP (Thin Shrink Small Outline Package) 20-lead package, which is designed for space-saving on PCBs. Its package type ensures that it is compatible with surface mount technology, which is beneficial for modern compact electronic assemblies.

Key features of the 74VHCT244ATTR include:

• High-speed CMOS technology
