TC4022BP

TC4022BP is octal Johnson counter consisting of 4 stage D-type flip-flops and equipped with decoder which convert the output to octal. Depending on the number of count pulses applied to CLOCK or CLOCK INHIBIT input, one of eight outputs Q0 through Q7 becomes UHH. The counter advances its counting state by rising edge of CLOCK when CLOCK INHIBIT=nLu and by falling edge of CLOCK INHIBIT when CLOCK="H". RESET input with level resets the counter to Q0="H" and Q1~Q7=WLn regardless of CLOCK and CLOCK INHIBIT.

The absolute maximum ratings of TC4022BP 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: 300mW; (6)operating ambient temperature range TA: -40~85°C; (7)storage temperature range Tstg: -65~150°C; (8)lead temp./time Tsol: 260°C·10sec.

The recommended operating conditions of TC4022BP 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.
