ATtiny13A Specs

• 20mA @5V (10mA @3V) continuous current PB0:1:5 (PWM,RST)
• 10mA @5V (5mA @3V) continuous current PB2:3:4 (ADC)
• 40mA @5V (20mA @3V) maximum peak 100ns current PB0:1:5 (PWM,RST)
• 20mA @5V (10mA @3V) maximum peak 100ns current PB2:3:4 (ADC)
• 60mA @5V output_lo sum current PB0+1+2+3+4+5
• 60mA @5V output_hi sum current PB0+1+2+3+4+5
• 120mA @5V output_hi + output_lo sum current

Example 40mA : PB0(HI) = 20mA LED to GND + PB1(LO) = 20mA LED to VCC
