ON Semiconductor 74VHCT244AM Octal Buffer/Line Driver

The ON Semiconductor 74VHCT244AM is a high-speed octal buffer and line driver designed to be compatible with low-power Schottky TTL (LSTTL). It is manufactured to provide high-performance in buffering and driving bus lines in systems that require high-speed and low power consumption. The device is particularly well-suited for driving bus lines or buffer memory address registers due to its high noise immunity and low power dissipation.

The 74VHCT244AM features eight non-inverting buffers with 3-state outputs that can be employed independently. Its 3-state outputs allow for connection to a bus-oriented system, facilitating the use of the device in a shared data environment. When the output enable (OE) input is high, the outputs are in a high impedance state, which effectively isolates the bus lines.

This integrated circuit is characterized for operation from -40°C to +85°C, making it reliable over a wide range of ambient temperatures. The 74VHCT244AM comes in a 20-lead Small Outline Integrated Circuit (SOIC) package, ensuring a compact footprint on the printed circuit board (PCB).

Key Features:

• Advanced high-speed CMOS technology
• Octal non-inverting buffers with 3-state outputs
• Input and output interface capability to systems at 5V supply
• Bus hold provided on data inputs to retain last input state when not driven
• Low quiescent power dissipation: 80μA maximum (20μA typical) at 25°C
• High output current: -8mA/8mA at 25°C
• Pin and function compatible with other standard logic families
• Latch-up performance exceeds 300mA
• ESD performance: Human Body Model >2000V; Machine Model >200V

The 74VHCT244AM is an ideal solution for applications requiring high-speed data transmission and buffering with minimal power consumption. Its robust performance and compatibility with other logic families make it a versatile choice for designers looking to optimize their digital systems. Whether used in computing, telecommunications, or industrial applications, the ON Semiconductor 74VHCT244AM offers reliability and efficiency in a compact form factor.
