SN74LVC126APWRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC126APWRG4 is an automotive-grade quadruple bus buffer gate with three-state outputs from the Texas Instruments LVC logic family. It operates within a supply voltage range of 1.65 V to 3.6 V and features four non-inverting input lines driving four output lines. The device provides high-level and low-level output currents of -24 mA and 24 mA, respectively, with a static current of 20 uA. Propagation delay is specified at 6.2 ns at 2.7 V and 5.7 ns at 3.3 V. It is housed in a TSSOP-14 package, supports surface mount installation, and functions reliably across a temperature range of -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific suffix G4 confirms lead-free RoHS compliance as per manufacturer specifications. Confirm the TSSOP-14 package type matches your PCB footprint requirements. Ensure the AEC-Q100 qualification aligns with your automotive application standards. Check the datasheet for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require isolated signal buffering with controlled drive strength. The LVC series offers improved power consumption compared to older logic families while maintaining compatibility with standard CMOS inputs. Consider the propagation delay specifications relative to your system clock speeds to ensure timing margins are met during signal transitions.
