Frequently Asked Questions
What is the operating voltage range of the SN74LVC126APWR?
The SN74LVC126APWR operates from a supply voltage (VCC) of 1.65V to 3.6V, making it suitable for 1.8V, 2.5V, and 3.3V logic systems. This wide range enables seamless integration in mixed-voltage designs without additional level-shifting components.
How does the 3-state output work on the SN74LVC126APWR?
Each of the four buffer channels has an independent active-high output enable (OE) pin. When OE is HIGH, the output follows the input signal. When OE is LOW, the output enters a high-impedance (Hi-Z) state, effectively disconnecting that channel from the bus. This allows multiple devices to share a common bus without contention.
What package does the SN74LVC126APWR use and what are its dimensions?
The SN74LVC126APWR comes in a 14-pin TSSOP (Thin Shrink Small Outline Package) with a 0.65mm pitch. This compact package measures approximately 5mm x 4.4mm, making it well-suited for high-density PCB layouts in portable and space-constrained applications.
What are common applications for the SN74LVC126APWR?
This device is commonly used for bus buffering, level translation, and signal isolation in microcontroller and FPGA designs. Typical applications include I2C/SPI bus expansion, memory interface buffering, industrial I/O modules, and any system requiring 3-state bus management in low-voltage logic environments.
Is the SN74LVC126APWR compatible with 5V logic inputs?
Yes, the SN74LVC126APWR features 5V-tolerant input and output pins, allowing it to interface directly with 5V TTL or CMOS logic signals even when powered at 3.3V or lower. This makes it ideal for bridging legacy 5V systems with modern low-voltage 3.3V or 1.8V logic.
