74ABT125CSC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT125CSC is a quad buffer with 3-STATE outputs housed in a 14-Lead Small Outline Integrated Circuit (SOIC) package. It operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of -40°C to +85°C. The device features non-inverting buffers with guaranteed latchup protection and high impedance glitch-free bus loading during power cycles. Output drive capabilities include a sink current of 64mA and a source current of 32mA. Propagation delays are specified at 4.6ns for data-to-output transitions and up to 6.8ns for output enable/disable times under standard test conditions.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and reel specifications. Ensure compatibility with JEDEC MS-012 standards for the SOIC-14 footprint. Confirm lead-free status per J-STD-020B requirements. Check for any recent product change notices that may affect pinout or electrical characteristics before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad buffer with 3-STATE outputs is required for 5V logic systems. Consider the 64mA sink and 32mA source drive capabilities for heavy load applications. Verify that the SOIC-14 package fits the available PCB space. Ensure the operating voltage range aligns with the system's 4.5V to 5.5V supply rails.
