74HC2G126DC,125

Overview

The 74HC2G126DC,125 is a dual buffer/line driver with 3-state outputs controlled by output enable inputs (nOE). It operates from a supply voltage of 2.0 V to 6.0 V and accepts CMOS level inputs. The device features input clamp diodes for interfacing with voltages exceeding VCC. It complies with JEDEC standard no. 7A and offers symmetrical output impedance, high noise immunity, low power dissipation, and balanced propagation delays. ESD protection exceeds 2000 V (HBM) and 200 V (MM). Operating temperatures range from -40 °C to +85 °C and -40 °C to +125 °C.

Feature Summary

• Dual buffer/line driver with 3-state outputs controlled by nOE inputs
• Wide operating voltage range from 2.0 V to 6.0 V
• Input levels compatible with CMOS logic standards
• ESD protection exceeding 2000 V (HBM) and 200 V (MM)

Applications

• Bus drivers in digital systems
• Line drivers for signal transmission
• Interface circuits requiring 3-state control

Procurement Notes

Verify the specific package type (VSSOP-8) and temperature range (-40 °C to +125 °C) against project requirements. Confirm that the CMOS input level compatibility matches the system's logic family. Ensure ESD handling procedures are followed during assembly due to the specified protection levels. Check for any recent product change notices regarding marking codes or manufacturing sites.

Selection Notes

Select this component when a dual-channel buffer with 3-state capability is required within a 2.0 V to 6.0 V supply range. It is suitable for applications needing CMOS-level input compatibility and robust ESD protection. Consider the VSSOP-8 package constraints for board space and thermal management. Verify that the propagation delay characteristics meet the timing requirements of the target application.

Part Context

This part belongs to the 74HC/HCT logic family, known for wide voltage operation and high noise immunity. The 'DC' suffix indicates the VSSOP-8 package variant. It is functionally similar to other 74HC2G126 variants but distinguished by its specific packaging and manufacturer designation.

Replacement Considerations

Check for direct replacements like the 74HCT2G126DC,125 if TTL-level inputs are needed instead of CMOS. Other packages such as TSSOP8 (74HC2G126DP) or XSON8 (74HC2G126GD) offer the same functionality with different physical dimensions.
