Unless otherwise stated, VDD = 5.0V ± 10%, no load on any output, and ambient temperature range TA = 0°C to 70°C. Parameters denoted with an asterisk ( * ) represent nominal

characterization data and are not currently production tested to any specific limits. Min. and Max. characterization data are ± 3

s from typical. Negative currents indicate current flows out of

the device.
