74LVC125ADTR2G

Overview

The MC74LVC125ADTR2G is a quad buffer and line driver from onsemi, belonging to the LVC logic family. It features four non-inverting channels with three-state outputs, housed in a TSSOP-14 package. The device operates within a supply voltage range of 1.65 V to 3.6 V. Key electrical characteristics include a propagation delay of 9 ns at 3.3 V and an output drive capability of 24 mA for both high and low states. It supports surface-mount installation and functions across an industrial temperature range of -55°C to +125°C.

Feature Summary

• Provides four independent non-inverting buffer channels with three-state output control
• Operates over a wide low-voltage supply range from 1.65 V to 3.6 V
• Delivers high-speed performance with 9 ns propagation delay at 3.3 V
• Supports strong load driving with 24 mA output current capability

Applications

• Memory module address and data bus buffering
• Clock distribution networks requiring low voltage operation
• Portable battery-powered consumer electronics systems
• High-density digital signal processing interfaces

Procurement Notes

Verify the exact manufacturer part number against official onsemi documentation before procurement. Confirm that the suffix 'ADTR2G' corresponds to the specific TSSOP-14 reel packaging variant. Ensure compliance with RoHS directives as indicated in the component specifications. Cross-reference the datasheet revision to confirm pinout and electrical parameters match your design requirements.

Selection Notes

Select this component when designing circuits requiring low-voltage operation between 1.65 V and 3.6 V. It is suitable for applications needing moderate speed with 9 ns delay and robust 24 mA drive strength. Consider the TSSOP-14 package for space-constrained surface-mount designs. Compare against HC or HCT families if higher voltage tolerance or different drive characteristics are required.

Part Context

This component belongs to the 74LVC series of CMOS logic buffers manufactured by onsemi. It is functionally similar to other quad three-state buffers but optimized for lower voltage supplies compared to standard 5V logic families. The device integrates four independent buffers, making it efficient for multi-channel signal routing in compact digital systems.

Replacement Considerations

Publicly documented substitutes include the MC74LCX125DTR2G. Verify compatibility regarding supply voltage ranges and package dimensions before substitution.
