74HC2G125DC,125

Overview

The Nexperia 74HC2G125DC,125 is a dual buffer and line driver featuring three-state outputs controlled by active-low enable inputs (nOE). It operates within a supply voltage range of 2.0 V to 6.0 V and utilizes CMOS technology for low power dissipation and high noise immunity. The device includes input clamp diodes to facilitate interfacing with voltages exceeding VCC using current-limiting resistors. Packaged in an 8-lead VSSOP (SOT765-1) plastic very thin shrink small outline package, it supports ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Dual buffer/line driver configuration with independent three-state outputs
• Wide supply voltage compatibility ranging from 2.0 V to 6.0 V
• Input protection via integrated clamp diodes for over-voltage tolerance
• High electrostatic discharge protection meeting JEDEC Class 2 and C3 standards

Applications

• Signal buffering in mixed-voltage digital systems
• Line driving for data transmission interfaces
• Bus holding applications requiring high-impedance states
• Voltage level translation between CMOS logic families

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component version aligns with the latest product data sheet revision to ensure accurate electrical characteristics. Check for any applicable environmental compliance documentation such as REACH or RoHS status directly from the manufacturer before finalizing procurement specifications.

Selection Notes

Select this component when a dual-channel buffer with tri-state control is required for CMOS logic applications. Ensure the operating voltage falls within the 2.0 V to 6.0 V range. Consider the VSSOP-8 package dimensions if space constraints are critical. Verify that the input voltage levels match the CMOS specification rather than TTL requirements.

Part Context

This part belongs to the 74HC/HCT family of high-speed silicon-gate CMOS logic devices manufactured by Nexperia. It is functionally similar to other dual buffers but specifically offers three-state output capability. The DC suffix denotes the VSSOP-8 package, distinguishing it from TSSOP or XSON variants within the same logical family.

Replacement Considerations

Direct substitutes include other 74HC2G125 variants from different manufacturers that meet identical pinout and electrical specifications. Cross-reference package dimensions carefully when replacing with alternative suppliers to ensure mechanical compatibility.
