Inverter Gates datasheet and documents for SN74HCS02QBQARQ1

SN74HCS02QBQARQ1

Inverter Gates Overview

The SN74HCS02QBQARQ1 is an automotive-grade quadruple 2-input NOR gate featuring Schmitt-trigger inputs. It operates within a supply voltage range of 2V to 6V and supports ambient temperatures from -40°C to +125°C. The device provides balanced CMOS push-pull outputs capable of ±7.8mA drive current at 6V. Propagation delay ranges from 6ns to 36ns depending on voltage. It is housed in a 14-pin WQFN package.

Inverter Gates Feature Summary

AEC-Q100 qualified for automotive applications with extended temperature support
Schmitt-trigger inputs provide high noise immunity and tolerance for slow signals
Balanced CMOS push-pull outputs ensure similar sourcing and sinking capabilities

Inverter Gates Applications

Alarm or tamper detect circuits
S-R latch configurations

Inverter Gates Procurement Notes

Verify the specific BQA (WQFN) package suffix matches the design footprint. Confirm AEC-Q100 qualification requirements are met for the target automotive grade. Ensure input termination strategies account for Schmitt-trigger characteristics to prevent undefined states.

Inverter Gates Selection Notes

Select this component when low power consumption and noise rejection are critical. The wide voltage range suits various automotive logic levels. Verify thermal resistance metrics against PCB layout constraints, as the WQFN package offers specific junction-to-ambient characteristics compared to SOIC or TSSOP variants.

Inverter Gates Part Context

This part belongs to the SN74HCS02-Q1 family of automotive quadruple 2-input NOR gates. It shares functional specifications with other packages like PW (TSSOP) and D (SOIC), differing primarily in physical dimensions and thermal properties. The BQA suffix specifically denotes the 14-pin WQFN form factor.

Inverter Gates FAQ

How should unused inputs be handled?

Unused inputs must not be left floating. They should be terminated to either VCC or ground using pullup or pulldown resistors to prevent undefined operational states.
