What are the key features of SN74LV244ANS?
- Octal 3-state outputs with active-low enable for efficient bus isolation and multiplexing in digital systems
- Low-voltage LV/LV-A family operation with 50pF load capacitance tolerance for driving long PCB traces
- Unidirectional buffering in compact 20-pin SOP package for address and data bus expansion
What is SN74LV244ANS used for?
The SN74LV244ANS is widely used in microprocessor and microcontroller systems to buffer address, data, and control buses, preventing signal degradation over long PCB traces or when driving multiple loads. It is effective in memory expansion boards, FPGA I/O expansion, and industrial controllers where 3-state bus isolation is essential. The 20-pin SOP package and LV-family logic levels make it straightforward to integrate into 3.3V and 5V compatible board designs.

Frequently Asked Questions
Which documented electrical capability is most relevant when evaluating SN74LV244ANS for a new design?
SN74LV244ANS is described as Texas Instruments SN74LV244ANS is an octal unidirectional bus buffer and line driver with 3-state outputs and active-low output enable control. It supports 50pF load capacitance and a 16mA sink current in a 20-pin SOP package. Available from stock with worldwide shipping. The documented 20 pins value should be checked against the complete datasheet limits for the intended circuit.
Before releasing SN74LV244ANS to layout, which package and operating limits require confirmation?
Engineering should verify the manufacturer package drawing, pin functions, supply and temperature limits, while retaining the documented 20 pins parameter as a concrete design-screening point.
How should procurement qualify an alternate for SN74LV244ANS without creating electrical or lifecycle risk?
An approved alternate must match function, package, qualification, and relevant ratings including the documented 20 pins value; compare current manufacturer datasheets before changing the BOM.
