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.

• Electrical characteristics equivalent to the HD74HC02

Supply voltage range: 2 to 6 V
Operating temperature range: –40 to +85°C

• | IOH | = IOL = 2 mA (min)
