74HCT2G126DP,125

Overview

The 74HCT2G126DP,125 is a dual buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level input signals. The device utilizes TSSOP8 plastic thin shrink small outline packaging with an 8-lead body width of 3 mm. It supports ambient temperatures from -40 °C to +125 °C and includes input clamp diodes for interfacing with voltages exceeding VCC.

Feature Summary

• Features three-state outputs controlled by active-low enable inputs
• Accepts TTL-level input signals for direct logic interface
• Includes input clamp diodes for over-voltage protection
• Provides symmetrical output impedance and high noise immunity

Applications

• Bus-oriented memory and address drivers
• Clock buffering and distribution
• High-speed data transmission lines

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets RoHS compliance standards for your region. Ensure the operating temperature range aligns with system requirements. Check for any recent product change notifications regarding marking codes or material composition updates before finalizing procurement.

Selection Notes

Select this component when TTL-compatible inputs are required in a CMOS environment. The HCT series ensures compatibility with standard TTL logic levels while maintaining CMOS power characteristics. Verify that the TSSOP8 package dimensions fit the available PCB footprint. Consider the maximum supply voltage limits when designing power rails.

Part Context

This part belongs to the Nexperia 74HCT family of logic integrated circuits. It is manufactured under license from NXP Semiconductors. The device is designed for general-purpose digital applications requiring signal buffering and line driving capabilities in compact surface-mount packages.

Replacement Considerations

The 74HC2G126DP serves as a functional alternative but requires CMOS-level input signals rather than TTL levels. Other variants include the DC package version for different board space constraints.
