ON Semiconductor 74VHC244SJ Octal Buffer/Line Driver

The 74VHC244SJ is a high-speed octal buffer/line driver designed by ON Semiconductor to provide the ideal solution for driving bus lines or buffering memory address registers. This integrated circuit is part of the VHC family, which is known for its versatility and high-performance in a wide range of digital applications.

Constructed with advanced silicon-gate CMOS technology, the 74VHC244SJ offers robust features that ensure minimal power consumption while delivering high-speed operation equivalent to LSTTL. The device is characterized for operation from -40°C to +85°C, making it suitable for industrial applications that require a wide operating temperature range.

Featuring eight non-inverting buffers with 3-state outputs, the 74VHC244SJ is ideal for driving heavily loaded, capacitive, or noisy lines. This makes it perfect for use in bus interface or signal buffering applications where high output drive is required. The 3-state outputs also allow for connection to a bus-organized system without the need for external pull-up resistors, as they can be placed in a high-impedance state.

The 74VHC244SJ comes in a slim 20-lead small outline package (SJ suffix), providing a compact footprint that is well-suited for space-constrained applications. Its pin configuration is carefully designed to simplify PCB layout, and the input and output voltage levels are compatible with TTL output levels, ensuring easy integration into existing designs.

Key features of the 74VHC244SJ include:

• High-speed: t<sub>PD 4.8 ns (typ) at V<sub>CC = 5V
• Low power dissipation: I<sub>CC = 4 µA (max) at T<sub>A = 25°C
• Power down protection is provided on all inputs and outputs
• Pin and function compatible with 74LS244

Whether it's for high-speed signal buffering, driving bus lines, or interfacing with memory registers, the 74VHC244SJ from ON Semiconductor is a reliable and efficient choice that ensures seamless operation in a variety of digital circuits.
