Frequently Asked Questions
What logic function does the SN74ALVC126DGVRE4 perform?
The SN74ALVC126DGVRE4 is a quad single-bit bus driver with tri-state outputs. It contains 4 independent non-inverting buffer/driver channels, each controlled by an active-high output enable pin. When enabled, the output follows the input; when disabled, the output is placed in a high-impedance (tri-state) condition. This allows multiple drivers to share a common bus without signal contention.
What voltage range does the SN74ALVC126DGVRE4 support?
The SN74ALVC126DGVRE4 belongs to Texas Instruments' ALVC advanced low-voltage CMOS family, which supports supply voltages from approximately 1.65-V to 3.6-V. This makes it suitable for modern low-voltage 1.8-V, 2.5-V, and 3.3-V digital systems, including FPGA I/O interfaces, microcontroller bus expansion, and DDR memory address buffers.
What is the output drive capability of the SN74ALVC126DGVRE4?
Each output of the SN74ALVC126DGVRE4 can sink up to 24-mA (Max I(ol) = 0.024 A) and supports a 50-pF load capacitance, which is typical for the ALVC family. This output drive strength is sufficient for buffering multi-load bus lines in typical PCB designs with standard trace impedances and several receiving device inputs.
What package does the SN74ALVC126DGVRE4 use?
The SN74ALVC126DGVRE4 is packaged in a 14-pin TVSOP (Thin Very Small Outline Package) surface-mount package, which has a very compact footprint for high-density board designs. The /E4 suffix indicates it is a green, RoHS-compliant, lead-free component with a JESD e4 moisture sensitivity level rating, meeting environmental requirements for global commercial markets.
What are common applications for the SN74ALVC126DGVRE4?
Common applications include memory address bus buffering, FPGA I/O expansion, microcontroller data bus isolation, level translation within 1.8-V to 3.3-V systems, and signal isolation on shared PCB buses. Its tri-state capability makes it especially useful where multiple devices must share a bus and each driver must be selectively enabled to avoid bus contention.
