* On products compliant to MIL-PRF-38535, this parameter is not production tested.
All typical values are at VCC = 3.3 V, TA = 25°C.
This is the bus-hold maximum dynamic current. It is the minimum overdrive current required to switch the input from one state to another.
§ For I/O ports, the parameter IOZ includes the input leakage current.
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
