74HC2G126GD,125

Overview

The 74HC2G126GD,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 2.0 V to 6.0 V and utilizes CMOS input levels. It is housed in an XSON8 package (SOT996-2) with dimensions of 3 x 2 x 0.5 mm. The component supports an ambient operating temperature range from -40 °C to +125 °C.

Feature Summary

• Provides high noise immunity and low power dissipation characteristics
• Includes input clamp diodes for interfacing with voltages exceeding VCC
• Offers symmetrical output impedance and balanced propagation delays
• Features ESD protection exceeding 2000 V under HBM testing

Applications

• Bus-oriented applications requiring signal buffering
• Clock drivers for timing distribution
• Memory address drivers for data routing
• Line drivers for transmission lines

Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status as specifications may be subject to revision. Check product status updates on official channels to ensure availability and lifecycle stage before finalizing procurement plans.

Selection Notes

Select this component when a dual-channel buffer with three-state control is required for CMOS logic families. Ensure the system voltage falls within the 2.0 V to 6.0 V operational range. Verify that the XSON8 package footprint aligns with the PCB layout constraints and thermal requirements for the intended application environment.

Part Context

This part belongs to the 74HC/HCT2G series of dual buffer/line drivers. It shares functional similarities with other members like the 74HCT2G126GD but differs in input switching thresholds. The GD suffix specifically denotes the XSON8 plastic extremely thin small outline package variant without leads.

Replacement Considerations

The 74HCT2G126GD,125 serves as a compatible alternative within the same family, offering TTL-compatible input levels instead of CMOS levels while maintaining identical pinout and packaging.
