Frequently Asked Questions
What is the supply voltage range of the SN74AUP1G125DCKR?
The SN74AUP1G125DCKR operates over a supply voltage range of 1.65V to 5.5V, making it compatible with a wide variety of digital logic families including 1.8V, 2.5V, 3.3V, and 5V systems. This flexibility allows it to be used in mixed-voltage designs without additional level-shifting circuitry.
What package does the SN74AUP1G125DCKR come in?
The SN74AUP1G125DCKR is housed in a 5-pin SC-70 (DCK) package, which is an extremely compact surface-mount package measuring approximately 2mm x 2mm. This small footprint makes it ideal for space-constrained applications such as smartphones, wearables, and other portable devices.
What is the propagation delay of the SN74AUP1G125DCKR?
The SN74AUP1G125DCKR has a typical propagation delay of approximately 4ns at 3.3V supply, enabling high-speed signal buffering. This low delay ensures minimal signal distortion when used in time-critical digital logic paths or fast bus communication interfaces.
Can the SN74AUP1G125DCKR be used for bus isolation?
Yes, the SN74AUP1G125DCKR features a tri-state output controlled by an active-low output enable pin (OE). When OE is driven high, the output enters a high-impedance state, effectively disconnecting the device from the bus. This makes it suitable for bus sharing, arbitration, and isolation in microcontroller and FPGA designs.
