Description
The HD74UH32 is high speed CMOS two input OR 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 Renesas uni logic series.
• Supplied on emboss taping for high-speed automatic mounting.
• Electrical characteristics equivalent to the HD74HC32
   Supply voltage range: 2 to 6 V
   Operating temperature range: –40 to +85°C
• | IOH | = IOL = 2 mA (min)
