Switching Specifications

Specifications hold over 3.0 V ≤ VCC ≤ 5.5 V and 0 ≤ TA ≤ 70°C and all typicals are at VCC = 5.0 V and TA

= 25°C unless otherwise specified. Listed conditions represent worst case values for the parameters under

test. Unspecified test conditions can be anywhere in their recommended operating range.
