74ABT125CSJ

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT125CSJ is a quad buffer with 3-STATE outputs housed in a 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm wide. It operates within a supply voltage range of +4.5V to +5.5V and 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. Propagation delays are specified at 4.6ns maximum for data-to-output transitions and up to 6.8ns for output enable/disable times under standard test conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Contains four independent non-inverting buffers with 3-STATE outputs
• Provides high impedance glitch-free bus loading throughout the entire power-up and power-down cycle
• Features nondestructive hot insertion capability to prevent damage during live circuit connection
• Ensures disable time is less than enable time to effectively avoid bus contention

Buffers, Drivers, Receivers, Transceivers Applications

• High impedance glitch-free bus loading applications
• Nondestructive hot insertion systems
• Bus-oriented memory address drivers
• Clock distribution buffers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package designation matches the required footprint, as the CSJ suffix indicates a 14-Lead SOP variant distinct from SOIC or TSSOP options. Confirm that the operating environment remains within the recommended voltage and temperature limits to ensure optimal performance and reliability. Check for any updated datasheet revisions 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 bus-oriented applications. Ensure the design accommodates the specific propagation delay and output drive capabilities defined in the datasheet. Verify compatibility with the system's voltage levels and timing requirements, particularly regarding the relationship between enable and disable times to prevent bus contention issues.
