製品説明
仕様・特性

MC14521B 24−Stage Frequency Divider The MC14521B consists of a chain of 24 flip−flops with an input circuit that allows three modes of operation. The input will function as a crystal oscillator, an RC oscillator, or as an input buffer for an external oscillator. Each flip−flop divides the frequency of the previous flip−flop by two, consequently this part will count up to 224 = 16,777,216. The count advances on the negative going edge of the clock. The outputs of the last seven−stages are available for added flexibility. http://onsemi.com MARKING DIAGRAMS Features • All Stages are Resettable • Reset Disables the RC Oscillator for Low Standby Power Drain • RC and Crystal Oscillator Outputs Are Capable of Driving External • • • • • Loads Test Mode to Reduce Test Time VDD′ and VSS′ Pins Brought Out on Crystal Oscillator Inverter to Allow the Connection of External Resistors for Low−Power Operation 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 Pb−Free Packages are Available* MAXIMUM RATINGS (Voltages Referenced to VSS) Parameter PDIP−16 P SUFFIX CASE 648 Value −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 SOIC−16 D SUFFIX CASE 751B 1 TA −55 to +125 °C Storage Temperature Range Tstg −65 to +150 °C Lead Temperature (8−Second Soldering) TL 260 °C 16 14521BG AWLYWW 1 16 SOEIAJ−16 F SUFFIX CASE 966 MC14521B ALYWG 1 mW Ambient Temperature Range 1 Unit VDD MC14521BCP AWLYYWWG 1 1 Symbol 16 DC Supply Voltage Range Input or Output Voltage Range (DC or Transient) A WL, L YY, Y WW, W G = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 2 of this data sheet. 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. © Semiconductor Components Industries, LLC, 2006 June, 2006 − Rev. 6 1 Publication Order Number: MC14521B/D
