For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.
§This parameter is specified by characterization.
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.
