DM13A-E Electrical Characteristics (VDD = 5.0 V, Ta = 25C unless otherwise noted) CHARACTERISTIC SYMBOL CONDITION MIN. TYP. MAX. UNIT Input Voltage “H” Level VIH CMOS logic level 0.8VDD VDD V Input Voltage “L” Level VIL CMOS logic level GND 0.2VDD Output Current Skew (Channel-to-Channel)*1 IOL1 VOUT = 0.5V Rrext = 22K 0.7 1.5 % VOUT = 0.5V Rrext = 4K 1.1 1.8 VOUT = 0.5V Rrext = 1K 2 3 Output Current Skew (Chip-to-Chip) *2 IOL2 VOUT = 0.5V Rrext = 22K 2.8 6 % VOUT = 0.5V Rrext = 4K 1.8 4 VOUT = 0.5V Rrext = 1K 1.4 3 Output Voltage Regulation % / VOUT VOUT = 0.5 V ~ 3 V (DC) Rrext = 4 K 0.1 0.5 % / V Supply Voltage Regulation % / VDD VDD = 3.3 V ~5 V (DC) Rrext = 4 K 0.1 0.5 Output Current Ripple (due to output voltage ripple) IRIP1 VOUT=1.5V 0.1V@5MHz Rrext = 4 K 0.5 1 % Output Current Ripple (due to supply voltage ripple) IRIP2 VDD=4V 0.1V@5MHz Rrext = 4 K 0.7 1.2 Average Output Current Skew (due to supply voltage ripple) IAO VDD=4V 0.1V@5MHz Rrext = 4 K 0.1 0.5 Supply Current IDD(off) power on all pins are open unless VDD and GND 4 7 mA IDD(off) input signal is static Rrext = 4K all outputs turn off 4.5 8 IDD(on) input signal is static Rrext = 4K all outputs turn on 4.5 8 *1 Channel-to-channel skew is defined as the ratio between (any I OUT ) of chip and (the average Iout) of chip. Equation: Skew(IOL1)={(IOUTn)/[ (IOUTmax + IOUTmin)/2]}-1 *2 Chip-to-chip skew is defined as the ratio between (the average of OUT0 to OUT15 ) and (the reference Iout). Equation: Skew(IOL2)={[(IOUT0+IOUT1+……IOUT14+IOUT15)/16]/(Iref.)}-1 ; Iref refer to page 10 |
