Frequently Asked Questions

What logic function do the ACT20 devices perform?

They perform Y = A • B • C • D or Y = A + B + C + D in positive logic via two 4-input NAND gates.

What is the output drive current of these gates?

They have ±24-mA output drive current, with fanout to 15 F devices.

What supply voltage range is recommended for operation?

The recommended supply voltage VCC is 4.5 V to 5.5 V.

How should unused inputs be handled?

All unused inputs must be held at VCC or GND to ensure proper device operation.
