CLVC126AQPWRG4Q1

Overview

The CLVC126AQPWRG4Q1 is an automotive-grade quad bus buffer gate from the SN74LVC126A series, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and features four non-inverting channels with three-state outputs. The device supports input levels compatible with both CMOS and TTL logic standards. It exhibits low static current consumption of 20 uA and delivers output drive currents of ±24 mA. Propagation delays are specified at 6.2 ns at 2.7 V and 5.7 ns at 3.3 V. It is qualified under AEC-Q100 standards for automotive applications and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments
• Quad configuration providing four independent non-inverting bus buffer gates
• Three-state output capability enabling effective bus line management and isolation
• Wide supply voltage operation supporting low-power systems from 1.65 V to 3.6 V

Applications

• Automotive electronic control unit (ECU) signal buffering
• Low-voltage data bus interface protection and driving
• Portable battery-powered equipment logic level translation
• Consumer electronics requiring high-speed signal integrity

Procurement Notes

Verify the complete part number including the G4 suffix to ensure lead-free compliance and specific packaging configuration. Confirm that the AEC-Q100 qualification status meets your specific automotive reliability requirements. Check the datasheet for the exact TSSOP-14 pinout and thermal characteristics relevant to your PCB layout. Ensure voltage levels on all inputs do not exceed the maximum ratings defined in the absolute maximum section.

Selection Notes

Select this component when designing automotive circuits requiring robust signal buffering with low power consumption. The LVC series offers faster switching speeds compared to standard HC logic while maintaining compatibility with 3.3 V and 5 V systems. Consider the TSSOP-14 package size if space constraints are critical. Verify that the required propagation delay and output drive current meet the specific timing and load requirements of your application design.

Part Context

This device belongs to the SN74LVC126A family of low-voltage CMOS logic devices. The 'CL' prefix indicates automotive grade qualification, while 'A' denotes the specific revision or variant within the LVC series. It serves as a key component for managing data flow in complex digital systems where signal isolation and voltage level shifting are necessary. The family is designed to bridge the gap between older 5 V logic standards and modern low-voltage microcontrollers.

Replacement Considerations

SN74LVC126AQDRG4Q1: Same functional specifications but housed in a SOIC-14 package instead of TSSOP-14.
