Typical values are at VCC = 5 V, TA = 25°C.
Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or
sample-and-hold techniques are preferable to minimize internal chip heating and more accurately reflect operational values. Otherwise, prolonged
shorting of a high output can raise the chip temperature well above normal and cause invalid readings in other parametric tests. In any sequence
of parameter tests, IOS tests should be performed last.
§ Per TTL-driven input (VIN = 3.4 V); all other inputs at VCC or GND
