Frequently Asked Questions
What is the operating voltage range of the SN74AUP1G125DSFR?
The SN74AUP1G125DSFR operates from a supply voltage of 0.8V to 3.6V, making it fully compatible with 1.8V and 2.5V logic systems. Its AUP (Advanced Ultra-Low Power) family design ensures minimal quiescent current even at the lower end of the voltage range, ideal for battery-powered designs.
How does the 3-state output work on the SN74AUP1G125DSFR?
The 3-state output is controlled by an active-low enable pin (OE#). When OE# is driven LOW, the output follows the input signal. When OE# is driven HIGH, the output enters a high-impedance state, effectively disconnecting from the bus. This allows multiple SN74AUP1G125DSFR devices to share a single bus line without signal contention, which is essential in multiplexed data bus architectures.
What package does the SN74AUP1G125DSFR use and what are its dimensions?
The SN74AUP1G125DSFR comes in a Small Outline No-lead (SON/DSF) 6-pin package, also known as X2SON. This package has a very small footprint of approximately 1.0mm x 1.0mm, making it one of the most compact options available for this logic function. It is well-suited for space-constrained PCB designs in smartphones, wearables, and IoT modules.
What are common applications for the SN74AUP1G125DSFR?
This device is commonly used as a bus buffer or line driver in portable electronics, IoT devices, and embedded systems requiring ultra-low power logic. Typical applications include shared I2C or SPI bus isolation, signal level buffering between microcontrollers and peripherals, output enable control in FPGA I/O banks, and data bus management in wearable health monitors and handheld industrial equipment.
Is the SN74AUP1G125DSFR RoHS compliant and available for mass production?
Yes, the SN74AUP1G125DSFR is fully RoHS compliant (Pbfree Code: Yes, JESD-609 Code: e4) and is rated for a 15-year estimated time of obsolescence (YTEOL: 15), indicating strong long-term availability. It is manufactured by Texas Instruments and available from authorized distributors worldwide, priced from approximately $0.18 per unit in volume, making it cost-effective for mass production runs.
