UPB571C

The UPB571C is a 500 MHz low power dual-modulus prescaler intended for use in PLL digital tuning systems in connection with NEC PLL LSI ICs.The device provides1/64,1/65, 1/32, 1/33,1/16 and 1/17 division ratio for pulse swallowing method and is guaranteed to operate up to 500 MHz over a -35 to +75 temperature range.In no event shall Sensitron Semiconductor be liable for any damages that may result from an accident or any other cause during operation of the user's units according to the datasheet(s). Sensitron Semiconductor assumes no responsibility for any intellectual property claims or any other problems that may result from applications of information, products or circuits described in the datasheets.

Features of the UPB571C are:(1)high frequency operation: 500 Miiz MAX. (Vin=400 m Vp-p); (2)Dual mode operation with pulse swallowing method:÷64/÷65, ÷32/÷33, ÷16/÷17; (3)single supply Voltage:  VCC=5.0V±10%; (4)low supply current:ICC=11 mA (TYP.); (5)small package:8 pin plastic dual in-line package (DIP).The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve UPB571C product characteristics. Before ordering, purchasers are advised to contact the Sensitron Semiconductor sales department for the latest version of the datasheet(s).

The absolute maximum ratings of the UPB571C can be summarized as:(1)supply voltage:-0.5 to 6.0 V;(2)storage temperature:-55 to 125;(3)operating temperature:-35 to 75;(4)input voltage:-0.5 to Vcc+0.5V;(5)output current:-10mA.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
