The NTE4063B is a 4−bit magnitude comparator in a 14−lead DIP-type package designed for use in computer and logic applications that require the comparison of two 4−bit words. This logic circuit determines whether one 4−bit word (Binary or BCD) is "less than", "equal to", or "greater than" a second 4−bit word. This device has eight comparing inputs (A3, B3, through A0, B0), three outputs (A < B, A = B, A > B) and three cascading inputs (A < B, A = B, A > B) that permit systems designers to expand the comparator function to 8, 12, 16 . . . 4N bits. When a single NTE4063B is used, the cascading inputs are connected as follows: (A < B) = low, (A = B) = high, (A > B) = low. For words longer than four bits, NTE4063B devices may be cascaded by connecting the outputs of the less−significant comparator to the corresponding cascading inputs of the more−significant comparator. Cascading inputs (A < B, A = B, and A > B) on the least significant comparator are connected to a low, a high and a low level, respectively.
VDD = −0.5 to +20V
Input voltage range, all inputs = −0.5 to VDD+0.5V
DC input current, any one input = &plusnm;10mA
TA = −55° to +100°C, PD = 500mW TA = +100° to +125°C = Derate linearly at 12mW/°C to 200mW
