Frequently Asked Questions
How does the 3-state output on the SN74AHC1G125DCKT work?
When the active-low output enable pin is driven high, the output enters a high-impedance (tri-state) mode, effectively disconnecting the buffer from the bus and allowing other devices to drive the line without contention.
What logic family does the SN74AHC1G125DCKT belong to and what are its electrical characteristics?
It belongs to the AHC (Advanced High-Speed CMOS) family, offering fast propagation delays and low power consumption. The output can sink up to 8mA and drive a load capacitance of 50pF, covering most standard logic-level interface requirements.
What package does the SN74AHC1G125DCKT use?
It comes in a 5-pin SOT-23 surface-mount package (JESD-30 code R-PDSO-G5), which is one of the smallest industry-standard packages available, making it perfect for space-constrained PCB designs.
Is the SN74AHC1G125DCKT RoHS compliant?
Yes, the SN74AHC1G125DCKT carries a JESD-609 code of e4, indicating it is a lead-free, RoHS-compliant device suitable for use in environmentally regulated products and modern manufacturing processes.
