What should engineers review before using SN74HC21QPWRQ1?

Check the 2 V to 6 V supply range, CMOS input thresholds, output loading, and the -40 C to 125 C operating range. Tie every unused input to VCC or GND.

What is the pinout of SN74HC21QPWRQ1?

Use the SN74HC21QPWRQ1 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about SN74HC21QPWRQ1 pinout to locate pins, power rails, and interface signals before layout.

AI summary

SN74HC21QPWRQ1 is a 14-pin automotive-qualified CMOS logic IC containing two independent 4-input AND gates for 2 V to 6 V systems.

Best for

Two independent 4-input AND functions
Automotive-temperature CMOS logic
2 V to 6 V digital logic rails

Avoid if

A different logic function is required
Inputs cannot be held at a defined logic level
The PCB cannot support 0.65 mm-pitch TSSOP assembly

Check before use

Verify VIH and VIL at the actual VCC.
Verify output current and load capacitance against the timing requirement.
Use the documented PW TSSOP land pattern.
