Frequently Asked Questions
What is the supply voltage range of the SN74LVC1G126DRLR?
The SN74LVC1G126DRLR operates from a supply voltage (VCC) of 1.65V to 5.5V, making it compatible with a wide range of modern low-voltage and legacy 5V logic systems. Its inputs are 5V tolerant, allowing seamless interfacing between different voltage domains.
How does the enable control work on the SN74LVC1G126DRLR?
The SN74LVC1G126DRLR uses an active-HIGH enable control (OE pin). When OE is HIGH, the output follows the input signal. When OE is LOW, the output is placed in a high-impedance (3-state) condition, effectively disconnecting it from the bus. This unidirectional control is ideal for bus arbitration and isolation applications.
What package does the SN74LVC1G126DRLR come in and what are its dimensions?
The SN74LVC1G126DRLR comes in a SOT-23-5 (JEDEC R-PDSO-F5) 5-pin flat lead package with a body size of approximately 1.6mm x 2.9mm. The DRLR suffix indicates a tape-and-reel packaging format for automated SMT assembly, with a standard reel quantity suitable for high-volume production.
What are common applications for the SN74LVC1G126DRLR?
Common applications include bus buffering and isolation in microcontroller systems, I/O expansion for FPGAs and CPLDs, level translation between 1.8V, 2.5V, 3.3V, and 5V logic systems, signal routing in portable electronics, IoT sensor nodes, industrial control boards, and any design requiring 3-state output control with a 50pF load capacitance capability.
What is a suitable replacement or alternative for the SN74LVC1G126DRLR?
Compatible alternatives include the SN74LVC1G126DBVR (SOT-23-5 non-reel), SN74LVC1G125DCKR (active-LOW enable), and ON Semiconductor NC7SZ126P5X. For equivalent function in a different package, the SN74LVC1G126DCK (SC-70-5) offers the same logic with a smaller footprint. Always verify voltage, timing, and pin compatibility before substituting.
