Frequently Asked Questions
What is the supply voltage range of SN74LV4T125PWR?
The SN74LV4T125PWR operates over a wide supply voltage range of 1.65V to 5.5V, making it suitable for both 1.8V, 3.3V, and 5V logic systems and enabling easy integration into mixed-voltage designs.
How does the output enable control work on SN74LV4T125PWR?
The SN74LV4T125PWR features an active-low output enable (OE) pin. When OE is driven LOW, the outputs are enabled and data passes through; when OE is HIGH, the outputs are placed in a high-impedance (3-state) condition, effectively disconnecting the buffer from the bus.
What package does SN74LV4T125PWR come in?
SN74LV4T125PWR is available in a 14-pin TSSOP (PDSO-G14) small outline package. It is Pb-free with JESD-609 e3 rating, suitable for standard SMD reflow soldering processes in high-density PCB layouts.
What are typical applications for the SN74LV4T125PWR?
This device is commonly used for bus buffering, signal isolation, and 3-state bus driving in microcontroller systems, FPGA I/O expansion, memory interfaces, and industrial control boards. Its LV-series family is especially popular in low-power portable and embedded designs.
