Frequently Asked Questions
What supply voltage range does the SN74AVC126PWR support?
The SN74AVC126PWR operates from 1.65 V to 3.6 V, covering 1.8 V, 2.5 V, and 3.3 V digital logic supply rails, making it suitable for modern low-voltage embedded systems and mixed-voltage bus interfaces in consumer and industrial electronics.
How is the output enable controlled on the SN74AVC126PWR?
Each of the four buffer channels has its own individual active-high output enable (OE) pin, allowing each bit to be independently enabled or placed in the high-impedance state, providing fine-grained bus isolation and signal multiplexing control.
What package does the SN74AVC126PWR use?
The SN74AVC126PWR is packaged in a 14-pin TSSOP (Thin Shrink Small Outline Package) with 0.65 mm pitch leads, supplied in tape-and-reel for high-volume surface-mount PCB assembly on compact embedded system boards.
What is the output drive current of the SN74AVC126PWR?
The SN74AVC126PWR can sink up to 12 mA (IOL) per output channel at 3.3 V supply, making it adequate for driving short PCB traces and typical digital inputs of FPGAs, microcontrollers, and peripheral ICs at 1.8 V to 3.3 V logic levels.
