UPB553AC

      The UPB553AC is a kind of VHF teo-modules prescaler.It is designed for use in measurement instruction and PLL Digital Tuning Systems in conjunction with UPD 1700 series.Advanced bipolar technology is utilized to realize high frequency operation with extremely low power consumptions.The device provides +16 and +17 division ratio for NEC's original pulse swallowing method,and is guaranteed to operate up to 130 MHz over the -35 to +75 temperature range with a V_CC variation from +4.5 V to +5.5 V.An included amplifier allows it to be operated with a small amplitude signal of 150 mVp-p.
      Here you can get some information about the UPB553AC  features.First is high frequency operation:150 MHz (+16) and 130 MHz (+17).The second is NEC's original pulse swallowing operation:+16/+17.The third is small input amplitude:Vin=150 mVP-p (MIN).Then is single supply voltage:V_CC=5.0 V±10%.Next is low supply current:I_CC=8.9 mA (TYP.).The sixth is incorporated buffer amplifier:V_O=1.2 Vp-p (TYP.).The last one is small package:8 pin plastic dual in-line package (DIP).
      What comes next is about the UPB553AC absolute maximum ratings.The V_CC (supply voltage) is from -0.5 to 6.0 V.The V_i (input voltage) is from  -0.5 to V_CC V.The I_O (output current) is 10 mA.The T_j (junction temperature) is +125.The T_stg (storage temperature) is from -55 to +125.Then is about the recommended operating conditions.The V_CC (supply voltage) is from 4.5 to 5.5 V.The T_a (ambient temperature) is from -35 to +75.The C_L (output load capacitance) is less than 10 pF.
      The following is about the UPB553AC electrical characteristics (V_CC=5 V±10%,T_a=-35 to +75).The typical I_CC (power supply current) is 8.9 mA and the maximum is 12.7 mA at V_CC=5.0 V,T_a=25.The typical P_C (power consumption) is 44.5 mW at V_CC=5.0 V,T_a=25.The minimum V_O (output voltage) is 0.9 Vp-p and the typical is 1.2 Vp-p at OUT terminal.The minimum V_in (input voltage) is 0.15 Vp-p and the maximum is 2.0 Vp-p at IN terminal.The minimum V_IH (high level input voltage) is 0.8V_CC V at PSC terminal.The maximum V_IL (low level input voltage) is 0.2V_CC V at PSC terminal.
