Frequently Asked Questions
What voltage range does the SN74AVC126DGV support?
The SN74AVC126DGV operates from a supply voltage range of 1.2V to 3.6V, covering common logic levels including 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. This wide range makes it ideal for modern low-voltage digital systems including mobile processors, FPGAs, and memory interfaces.
How does the enable control work on the SN74AVC126DGV?
The SN74AVC126DGV features four independent active-high output enable pins, one per buffer channel. When the enable pin is high, the corresponding output reflects the input signal; when low, the output is placed in a high-impedance state. This allows each of the four channels to be independently controlled for selective bus driving.
What package is the SN74AVC126DGV available in?
The SN74AVC126DGV is housed in a 14-pin TSSOP (Thin Shrink Small Outline Package), a very compact surface-mount package with a 0.65mm pin pitch that is well-suited for high-density PCB designs in portable electronics and space-constrained applications.
What are typical applications for the SN74AVC126DGV?
Typical applications include bus buffering between low-voltage logic blocks in mobile phones, tablets, and IoT devices; signal isolation and enable control in multi-master bus designs; and unidirectional data path switching in embedded systems requiring selective connection between different subsystem interfaces operating at compatible voltage levels.
