Frequently Asked Questions
What is the supply voltage range of the SN74LVC244ARWPR?
The SN74LVC244ARWPR operates from a supply voltage (VCC) of 1.65V to 3.6V, making it compatible with modern low-voltage logic systems and 3.3V microcontrollers.
What package does the SN74LVC244ARWPR use, and what are its dimensions?
The SN74LVC244ARWPR comes in a QFN-20 package (JESD-30 code R-PQCC-N20), a compact Quad Flat No-Lead form factor suitable for high-density PCB designs with reduced parasitic inductance.
What are typical applications for the SN74LVC244ARWPR?
Typical applications include bus buffering and line driving in microcontroller systems, FPGA I/O expansion, address/data bus isolation in memory interfaces, and signal level translation in 1.8V to 3.3V mixed-voltage designs.
How does the enable-low control work on the SN74LVC244ARWPR?
The SN74LVC244ARWPR features an active-low output enable (OE) pin. When OE is LOW, the outputs are enabled and reflect the input logic states. When OE is HIGH, all outputs enter a high-impedance (3-state) condition, allowing multiple devices to share a common bus.
