MC14585BCPG

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. http://onsemi.com 1 SOIC−16 D SUFFIX CASE 751B PIN ASSIGNMENT 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 NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable* This Device is Pb−Free and is RoHS Compliant B2 1 16 VDD A2 2 15 A3 (A = B)out 3 14 B3 (A u B)in 4 13 (A u B)out (A t B)in 5 12 (A t B)out (A = B)in 6 11 B0 A1 7 10 A0 VSS 8 9 B1 MARKING DIAGRAM MAXIMUM RATINGS (Voltages Referenced to VSS) Parameter 16 Symbol Value Unit VDD −0.5 to +18.0 V 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 DC Supply Voltage Range Input or Output Voltage Range (DC or Transient) Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. 1. Temperature Derating: “D/DW” Package: –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 ≤ (Vin or Vout) ≤ 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. © Semiconductor Components Industries, LLC, 2014 July, 2014 − Rev. 9 1 14585BG AWLYWW 1 A WL, L YY, Y WW, W G = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package ORDERING INFORMATION Package Shipping† MC14585BDG SOIC−16 (Pb−Free) 48 Units / Rail MC14585BDR2G SOIC−16 (Pb−Free) 2500/Tape & Reel NLV14585BDR2G* SOIC−16 (Pb−Free) 2500/Tape & Reel Device †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D.
