Product details

Quad XOR gate with Schmitt-trigger inputs for automotive logic

The wide supply range of 2V to 6V lets it bridge 3.3V and 5V logic domains without a translator, and the Schmitt-trigger inputs clean up slow or noisy edges from sensors, switch contacts, or long harness runs common in automotive ECUs.

The 2 µA maximum quiescent current and 7.8 mA output drive are typical for the 74HCS family. Propagation delay is 12 ns at 6V and 50 pF load.

The SN74HCS86QBQARQ1 is an active product. For cross-reference, the SN74HCS14QDRQ1 is also AEC-Q100 qualified but is a hex inverter, not a functional replacement.

Frequently asked questions

Is SN74HCS86QBQARQ1 pin compatible with standard 74HC86?

The SN74HCS86QBQARQ1 shares the same 14-pin footprint and logic function (quad 2-input XOR) as a standard 74HC86 in a 14-WQFN package. However, the standard 74HC86 is typically offered in SOIC or TSSOP, not the 3 mm x 2.5 mm WQFN. Verify the PCB land pattern — the WQFN has an exposed pad that a standard SOIC-14 footprint does not accommodate.
