74LVC2G125RA3-7

Overview

The 74LVC2G125RA3-7 is a dual buffer gate with 3-state outputs manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.65V to 5.5V and features IOFF circuitry for partial power-down applications. The device utilizes Schmitt trigger inputs to tolerate slower rise and fall times, providing hysteresis typically at 100mV when VCC is 3.0V. It is housed in an X2-DFN1210-8 package.

Feature Summary

• Dual buffer gates with 3-state outputs designed for operation across a wide supply voltage range from 1.65V to 5.5V
• IOFF circuitry disables outputs to prevent damaging current backflow during partial power-down conditions
• Schmitt trigger action at all inputs provides tolerance for slower input rise and fall times

Applications

• Voltage level shifting
• General purpose logic
• Power down signal isolation

Procurement Notes

Verify the specific ordering suffix RA3 corresponds to the X2-DFN1210-8 package configuration before procurement. Confirm that the required tape and reel quantity aligns with standard factory packaging specifications. Ensure compatibility with RoHS and halogen-free environmental standards as defined by the manufacturer.

Selection Notes

Select this component when a dual non-inverting buffer with controlled output enable signals is required. The inclusion of Schmitt triggers makes it suitable for noisy environments or slow signal transitions. Verify that the operating voltage requirements of the system fall within the specified 1.65V to 5.5V range for proper functionality.

Part Context

This part belongs to the 74LVC series of logic devices, which are designed for low-voltage CMOS applications. The LVC family offers performance comparable to standard TTL levels while operating at lower supply voltages. The dual-gate configuration allows for efficient space utilization in compact electronic designs requiring multiple buffering functions.

Replacement Considerations

Compatible substitutes include other 74LVC2G125 variants such as 74LVC2G125HD4-7 and 74LVC2G125HK3-7, which share identical logical functions but differ in physical package dimensions.
