Product details

The open-drain output sinks 7.8 mA per channel. AEC-Q100 qualification is the primary sourcing gate for this part.

Open-drain outputs and wired-AND configuration

The open-drain output stage lets multiple gate outputs connect to a common pull-up resistor, forming a wired-AND bus. Input logic levels scale with supply: a low threshold of 1V to 3V and a high threshold of 1.5V to 4.2V over the 2V to 6V supply range.

ROHS3 compliant. The Q1 suffix denotes the automotive-qualified variant with PPAP documentation available.

Timing and signal integrity

Maximum propagation delay is 11 ns at 6V supply with 50 pF load. Quiescent current is 2 µA maximum.

Frequently asked questions

What is the difference between SN74HCS09QDR and SN74HCS09QDRQ1?

The Q1 suffix indicates AEC-Q100 qualification with PPAP documentation support. The non-Q1 SN74HCS09QDR is the same die in the same 14-SOIC package but without automotive qualification. For tier-1 automotive OEM submissions, specify the Q1 variant.

What is the closest functional second-source for SN74HCS09QDRQ1?

The SN74HCS04PWR is a hex inverter from the same 74HCS family with Schmitt-trigger inputs and 7.8 mA output drive, but it is an inverter, not an AND gate, and comes in a TSSOP-14 package rather than SOIC-14. For a pin-compatible AND gate alternative within the same family, there is no direct second-source listed. The SN74LV08ADR is a quad 2-input AND gate in SOIC-14 with 12 mA output drive and faster 7.9 ns propagation delay at 5V, but it lacks Schmitt-trigger inputs and AEC-Q100 qualification.
