Product Details SN74LV244APW is an octal non-inverting buffer and line driver from the 74LV logic family, designed to strengthen and distribute digital signals between controllers, memory devices, connectors and other logic circuits. The device integrates eight independent buffer channels arranged as two groups of four, providing flexible signal-driving capability in a compact surface-mount package.Each group of four outputs has an independent output-enable control. When the corresponding output-enable input is inactive, the associated outputs enter a high-impedance state. This three-state architecture allows SN74LV244APW to be used for shared buses and other digital interfaces where multiple devices may connect to common signal lines.The device operates from a 2V to 5.5V supply range, providing flexibility for different logic-system voltage levels. Its mixed-mode voltage capability allows the device to be integrated into systems where different digital interface requirements need to be accommodated.SN74LV244APW uses non-inverting logic, meaning the output follows the logical state of its corresponding input when the channel is enabled. The eight channels can therefore be used to buffer address lines, data signals, control signals and other digital logic paths that require additional drive capability.The device supports output drive currents of up to 16mA under specified conditions. This capability allows it to drive logic inputs over longer PCB traces, connectors and other interconnects where signal integrity may otherwise be affected by loading or trace capacitance. TI also identifies signal buffering between controllers and other devices as a typical application for the SN74LV244A family.SN74LV244APW is supplied in a 20-pin TSSOP package, providing a relatively compact footprint for digital circuit boards. The package includes the eight input channels, eight three-state outputs, two output-enable controls, power and ground connections.The three-state outputs make the device particularly useful for bus-oriented architectures. When a group is disabled, its outputs can be disconnected electrically from the associated bus, allowing another device to control the same signal lines. This makes the device suitable for memory interfaces, microcontroller expansion, data buses and other shared digital connections.SN74LV244APW can also be used as a general-purpose signal buffer when digital signals need additional drive strength before reaching another section of a circuit. Typical applications include PCB signal routing, connector interfaces, microcontroller interfaces, memory systems and digital control equipment.The device is specified for an operating temperature range of -40°C to +125°C. Its combination of eight non-inverting channels, independent output enables, three-state outputs, wide supply-voltage range and compact TSSOP packaging makes it a practical logic-buffer solution for a broad range of electronic systems.When designing with SN74LV244APW, engineers should verify the required supply voltage, input and output logic levels, output loading, propagation delay, enable timing and bus-sharing conditions according to the specific application and the latest Texas Instruments documentation.
