TC4020BF

The TC4020BF belongs to TC4020B family which is 14 stage ripple carry binary counter having asynchronous clear function. The counter advances its counting stage by falling edge of CLOCK input. When RESET input is placed "H" all the circuits are reset regardless of input making all the outputs( Q1, Q4 to Q14)to be "L". This is most suitable for frequency dividers control circuits and timing circuits.

The absolute maximum ratings of TC4020BF are (1)DC supply voltage VDD: VSS-0.5~VSS+20V; (2)input voltage VIN: VSS-0.5~VDD+0.5V; (3)output voltage VOUT: VSS-0.5~VDD+0.5V; (4)DC input current IIN: ±10mA; (5)power dissipation PD: 300(DIP/180(SOIC))mW; (6)operating ambient temperature range TA: -40~85°C; (7)storage temperature range Tstg: -65~150°C.

The recommended operating conditions of TC4020BF can be summarized as (1)DC supply voltage VDD: 3-18V; (2)input voltage VIN: 0 to VDD V; (3) operating temperature Topr: -40 to 85°C. If you want to know more about this IC, please go to our website for more detail imformation.
