(TOP VIEW)

In these devices, each circuit functions as a

quadruple NOR gate. They perform the Boolean

function Y = A • B or Y = A + B in positive logic.

However, because of the Schmitt action, the

inputs have different input threshold levels for

positive- and negative-going signals.

20 19

These circuits are temperature compensated and

can be triggered from the slowest of input ramps

and still give clean jitter-free output signals.

The SN54HC7002 is characterized for operation

over the full military temperature range of –55°C

to 125°C. The SN74HC7002 is characterized for

operation from –40°C to 85°C.

‡

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace

length of zero.
