* On products compliant to MIL-PRF-38535, this parameter does not apply.
All typical values are at VCC = 5 V.
This parameter is characterized, but not production tested.
§The parameters IOZH and IOZL include the input leakage current.
Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
#This limit may vary among suppliers.
||This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
PRODUCT PREVIEW information concerns products in the formative or
design phase of development. Characteristic data and other
specifications are design goals. Texas Instruments reserves the right to
change or discontinue these products without notice.
