(1) Unless otherwise specified min/max limits apply across the −55°C to +125°C temperature range for the DS9638M and across the 0°C to
+70°C range for the DS9638C. All typicals are given for V_CC = 5V and T_A = 25°C.
(2) All currents into the device pins are positive; all currents out of the device pins are negative. All voltages are referenced to ground
unless otherwise specified.
