Product details

What the ratings mean for the BOM

The SN74HCS00BQAR: The Schmitt-trigger inputs provide hysteresis that cleans up slow or noisy edges – critical for long trace runs, sensor interfaces, or oscillator circuits where a standard CMOS input would chatter. The 2 µA maximum quiescent current means this gate adds negligible standby draw, so it fits into battery-backed or always-on domains without a power budget hit. The 7.8 mA output drive is enough to drive a single standard CMOS load or a low-power LED, but you will need a buffer for heavier fan-out. The -55°C to 125°C operating range covers underhood automotive, downhole, and avionics – capable is not qualified, but the thermal headroom is there for designs that need to survive beyond commercial limits.

Lifecycle and sourcing reality

This part carries an Active product status with ROHS3 compliance.

Frequently asked questions

Is SN74HCS00BQAR compatible with 3.3V logic?

Yes. The 2V to 6V supply range covers both 3.3V and 5V systems directly, and the Schmitt-trigger inputs accept the logic levels from those rails without external level shifting. Input logic low is 1V to 3V; input logic high is 1.5V to 4.2V, so a 3.3V CMOS output drives it cleanly.

What are the alternatives to SN74HCS00BQAR?

The SN74LV00APWR is a quad 2-input NAND gate in the 74LV family, but it lacks Schmitt-trigger inputs and operates only up to 85°C. If you need an inverter instead of a NAND, the SN74HCS04PWR or the automotive-qualified SN74HCS14QDRQ1 are in the same 74HCS series with Schmitt-trigger inputs and similar supply and temperature ratings.
