1 / 7 page © Semiconductor Components Industries, LLC, 2006 June, 2006 − Rev. 6 1 Publication Order Number: MC14585B/D MC14585B 4−Bit Magnitude Comparator 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. Applications include logic in CPU’s, correction and/or detection of instrumentation conditions, comparator in testers, converters, and controls. Features • Diode Protection on All Inputs • Expandable • Applicable to Binary or 8421−BCD Code • Supply Voltage Range = 3.0 Vdc to 18 Vdc • Capable of Driving Two Low−Power TTL Loads or One Low−Power Schottky TTL Load over the Rated Temperature Range • Can be Cascaded − See Figure 3 • Pb−Free Packages are Available* MAXIMUM RATINGS (Voltages Referenced to VSS) Parameter Symbol Value Unit DC Supply Voltage Range VDD − 0.5 to +18.0 V Input or Output Voltage Range (DC or Transient) Vin, Vout − 0.5 to VDD + 0.5 V Input or Output Current (DC or Transient) per Pin Iin, Iout ±10 mA Power Dissipation per Package (Note 1) PD 500 mW Ambient Temperature Range TA − 55 to +125 °C Storage Temperature Range Tstg − 65 to +150 °C Lead Temperature (8−Second Soldering) TL 260 °C Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. 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−impedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS v (Vin or Vout) v VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open. *For additional information on our Pb−Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D.
