The MC14585B 4–Bit Magnitude Comparator is constructed with

complementary MOS (CMOS) enhancement mode devices. The

circuit has eight comparing inputs (A3, B3, A2, B2, A1, B1, A0, B0),

three cascading inputs (A< B, A = B, and A > B), and three outputs (A

< B, A = B, and A > B). This device compares two 4–bit words (A and

B) and determines whether they are “less than”, “equal to”, or “greater

than” by a high level on the appropriate output. For words greater than

4–bits, units can be cascaded by connecting outputs (A > B), (A < B),

and (A = B) to the corresponding inputs of the next significant

comparator. Inputs (A < B), (A = B), and (A > B) on the least

significant (first) comparator are connected to a low, a high, and a low,

respectively.

2. Maximum Ratings are those values beyond which damage to the device

may occur.

3. Temperature Derating:

Plastic “P and D/DW” Packages: – 7.0 mW/ C From 65 C To 125 C

This device contains protection circuitry to guard against damage due to high

static voltages or electric fields. However, precautions must be taken to avoid

applications of any voltage higher than maximum rated voltages to this

high–impedancecircuit. For proper operation, V and V should be constrained

out

to the range V

(V or V

)

out

Unused inputs must always be tied to an appropriate logic voltage level (e.g.,

either V or V ). Unused outputs must be left open.

6. To calculate total supply current at loads other than 50 pF:

I (C ) = I (50 pF) + (C – 50) Vfk

where: I is in µA (per package), C in pF, V = (V – V ) in volts, f in kHz is input frequency, and k = 0.001.
