Overview
HD74UH02 2-input NOR Gate ADE-205-015A(Z) 2nd Edition August 1993 Description The HD74UH02 is high speed CMOS two input NOR gate using silicon gate CMOS process.
With CMOS low power dissipation, it provides high speed equivalent to LS-TTL series.
The internal circuit of three stages construction with buffer provides wide noise margin and stable output.
Features • Encapsulated in very small 5pins package of 2.
9 × 1.
6 × 1.
1 mm, the efficiency to mount on substrate is significantly improved.
• The basic gate function is lined up as hitachi uni logic series.
• Supplied on embos taping for high speed automatic mounting.
