ON Semiconductor 74LVX244M Low Voltage Octal Buffer/Line Driver

The 74LVX244M is a high-performance, low-voltage octal buffer and line driver designed to operate as memory address drivers, clock drivers, and bus-oriented transmitters/receivers. Manufactured by ON Semiconductor, this device is part of the 74LVX family, which is renowned for its low power consumption and high speed. It is particularly well-suited for down translation to a lower voltage I/O interface and can be used in a wide range of applications from PCs and notebooks to data communication and telecommunication systems.

The 74LVX244M features eight non-inverting buffers with 3-state outputs to ensure that multiple components can be connected to a bus without interference. The 3-state controls operate the device in either a normal logic mode where the outputs reflect the inputs, or in a high-impedance state where the outputs are effectively disconnected from the circuit, thus preventing any potential damage from data collision.

Constructed with an advanced CMOS technology, the 74LVX244M offers optimum speed-power performance, which makes it an ideal choice for interfacing with high-speed microprocessors without the high power consumption typically associated with such speeds. The device can handle a wide operating voltage range of 2.7V to 3.6V, which provides a flexible power design for mixed-voltage systems and supports low voltage operation for battery-powered electronics.

Key features of the 74LVX244M include:

• Low voltage operation: 2.7V to 3.6V
• High-speed operation: t_PD 3.8 ns (max) at 3.3V
• Power-down protection on inputs and outputs
• Supports live insertion and withdrawal (partial power-down mode)
• Low quiescent current: 20µA (max) at 25°C
• Low noise: Volp = 0.8V (max)
• Available in SOP, TSSOP, and TVSOP packages

Furthermore, the 74LVX244M is designed with an input and output interface capability for partial power-down mode operation, which allows the inputs to remain active while the outputs are in the high-impedance state. This feature is particularly useful in power-saving modes and can contribute to the extended battery life of portable devices.

ON Semiconductor's commitment to quality ensures that the 74LVX244M meets the stringent requirements of the electronics industry, providing both reliability and performance for critical applications.
