74HCT2G126GD,125

Overview

The 74HCT2G126GD,125 is a dual buffer and line driver manufactured by NXP Semiconductors. It features two non-inverting buffers with three-state outputs controlled by active-low output enable inputs (nOE). The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes TTL input levels. It is housed in an XSON8 package (SOT996-2) measuring 3 x 2 x 0.5 mm. The component supports an ambient operating temperature range from -40 °C to +125 °C.

Feature Summary

• Dual buffer configuration with independent three-state outputs
• TTL-compatible input logic levels for direct interfacing
• Low power dissipation characteristics typical of CMOS technology
• High noise immunity and balanced propagation delays

Applications

• Bus-oriented transmissions
• Clock buffering and distribution
• Memory address drivers

Procurement Notes

Verify the specific ordering suffix GD,125 against current NXP documentation to confirm the XSON8 package type and tape-and-reel packaging details. Ensure that the HCT logic family requirements align with the target system's voltage and timing specifications before finalizing procurement.

Selection Notes

Select this component when a dual buffer with three-state control is required for 5 V logic systems. The HCT series ensures compatibility with standard TTL inputs. Consider the XSON8 package dimensions if space-constrained surface mount layouts are necessary for the application design.

Part Context

This part belongs to the 74HCT2G126 series of dual buffers. It shares functional similarities with the 74HC2G126 but differs in input threshold voltages to support TTL signaling. The GD suffix denotes the specific XSON8 plastic package variant without leads.
