Product details

Quiescent current and output drive

Maximum quiescent current is 2 µA across the temperature range, making this gate suitable for always-on or wake-up circuits where standby draw matters. Each output can source or sink 7.8 mA — enough to drive a downstream CMOS logic input or a low-current LED indicator, but not a relay coil or high-capacitance load without a buffer.

Lifecycle and sourcing

For dual-sourcing resilience, the 74HCS family includes other logic functions (inverters, NAND gates) in the same package and temperature grade, but no pin-compatible second-source OR gate is listed in the official cross-reference.

Frequently asked questions

Is SN74HCS32QBQARQ1 automotive qualified?

Yes, it is AEC-Q100 qualified and carries an Automotive grade rating. The operating temperature range is -40°C to 125°C, covering under-hood and chassis applications. PPAP documentation is available through standard automotive supply channels.

What package does SN74HCS32QBQARQ1 come in?

It comes in a 14-WFQFN exposed pad package (3 x 2.5 mm), also referred to as 14-WQFN. Mounting is surface mount.
