1 / 6 page © Semiconductor Components Industries, LLC, 2014 August, 2014 − Rev. 9 1 Publication Order Number: MC14028B/D MC14028B BCD-To-Decimal Decoder Binary-To-Octal Decoder The MC14028B decoder is constructed so that an 8421 BCD code on the four inputs provides a decimal (one−of−ten) decoded output, while a 3−bit binary input provides a decoded octal (one−of−eight) code output with D forced to a logic “0”. Expanded decoding such as binary−to−hexadecimal (one−of−sixteen), etc., can be achieved by using other MC14028B devices. The part is useful for code conversion, address decoding, memory selection control, demultiplexing, or readout decoding. Features • Diode Protection on All Inputs • 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 • Positive Logic Design • Low Outputs on All Illegal Input Combinations • Similar to CD4028B • 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 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 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” 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 ≤ (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. http://onsemi.com See detailed ordering and shipping information in the package dimensions section on page 2 of this data sheet.
