Overview
HD74LV27A Triple 3-input Positive NOR Gates ADE-205-256 (Z) 1st Edition March 1999 Description The HD74LV27A performs the Boolean functions Y = A•B•C or Y = A+B+C in positive logic.
Low-voltage and high-speed operation is suitable for the battery-powered products (e.
g.
, notebook computers), and the low-power consumption extends the battery life.

1.
The input and output voltage ratings may be exceeded even if the input and output clamp-current ratings are observed.
2.
This value is limited to 5.
5 V maximum.
3.
The maximum package power dissipation was calculated using a junction temperature of 150°C.
