74HCT2G125GD,125

Overview

The Nexperia 74HCT2G125GD,125 is a dual buffer and line driver featuring three-state outputs controlled by output enable inputs. It belongs to the 74HCT logic series, utilizing high-speed silicon-gate CMOS technology with TTL input switching levels. The device operates within a supply voltage range of 2.0 V to 5.5 V and supports an operating temperature from -40 °C to +125 °C. Packaged in an 8-XSON (2x3) surface-mount format, it provides symmetrical output impedance and balanced propagation delays for reliable signal transmission.

Feature Summary

• Dual buffer/line driver configuration with three-state outputs
• TTL input switching levels compatible with standard logic families
• Wide supply voltage range supporting mixed-voltage environments
• High noise immunity and low power dissipation characteristics

Applications

• Signal buffering in digital communication systems
• Line driving for data transmission interfaces
• Voltage translation between different logic domains
• Clock distribution networks requiring three-state control

Procurement Notes

Verify the specific suffix GD against the official Nexperia datasheet to confirm the 8-XSON package type and tape-and-reel orientation. Ensure the order quantity matches the manufacturer's standard packaging requirements. Confirm RoHS compliance status and lead times directly with authorized distributors or Nexperia sales representatives prior to finalizing procurement orders.

Selection Notes

Select this component when a dual buffer with three-state capability and TTL-compatible inputs is required. It is suitable for applications needing operation across a wide voltage range from 2.0 V to 5.5 V. Consider the 8-XSON package for compact surface-mount designs. Verify that the HCT input levels match the source logic family rather than using HC variants which require CMOS levels.

Part Context

This part is part of the 74HCT2Gxx series of small-signal logic ICs from Nexperia. These devices are designed for low-power, high-speed operations in portable and battery-powered applications. The 74HCT2G125 specifically functions as a buffer, providing isolation and drive strength while maintaining signal integrity through its three-state output control mechanism.

Replacement Considerations

The 74AHC2G125DC,125 is listed as a similar alternative. Note that AHC variants use CMOS input levels, whereas this HCT part uses TTL levels. Verify input compatibility before substitution. Other packages in the same logical family may also serve as replacements if pinout and electrical specifications align.
