74HC2G125DP,125

Overview

The Nexperia 74HC2G125DP,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 input levels. The device includes input clamp diodes for interfacing with voltages exceeding VCC. Packaged in an 8-lead TSSOP (SOT505-2) plastic thin shrink small outline package, it supports ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Dual buffer/line driver configuration with three-state outputs
• Wide supply voltage operation from 2.0 V to 6.0 V
• Input clamp diodes allow interface to voltages exceeding VCC
• High noise immunity and low power dissipation

Applications

• Signal buffering in mixed-voltage environments
• Line driving for high-speed data transmission
• Interface circuits requiring voltage translation

Procurement Notes

Verify the specific ordering suffix '125' corresponds to the TSSOP8 package variant SOT505-2. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Ensure design compliance with the absolute maximum ratings regarding supply voltage and output current to prevent permanent damage.

Selection Notes

Select this component when a dual non-inverting buffer with three-state control is required. The HC logic family provides CMOS input switching levels suitable for standard digital interfaces. Consider the wide supply voltage range if the system requires operation between 2.0 V and 6.0 V. Verify pin compatibility with the target PCB footprint for the SOT505-2 package.

Part Context

This part belongs to the Nexperia 74HC/HCT2G series of dual logic devices designed for space-constrained applications. The 2G series utilizes a compact 8-lead package format, offering multiple logic functions including buffers, inverters, and gates within a minimal footprint. The DP suffix specifically denotes the TSSOP8 package type.

Replacement Considerations

Direct replacements include other 74HC2G125 variants from different manufacturers or Nexperia's 74HCT2G125DP,125 if TTL input levels are acceptable. Cross-reference package dimensions for SOT505-2 compatibility.
