SCLS076G – DECEMBER 1982 – REVISED DECEMBER 2020
SNx4HC02 Quadruple 2-Input Positive-NOR Gates
1 Features
• Buffered inputs • Wide operating voltage range: 2 V to 6 V • Wide operating temperature range:
–40°C to +85°C • Supports fanout up to 10 LSTTL loads • Significant power reduction compared to LSTTL
logic ICs
2 Applications
• Alarm / tamper detect circuit • S-R latch
3 Description
This device contains four independent 2-input NOR gates. Each gate performs the Boolean function Y = A + B in positive logic.
