* On products compliant to MIL-PRF-38535, this parameter does not apply.
† All typical values are at VCC = 5 V.
‡ For VCC between 2.1 V and 4 V, OE should be less than or equal to 0.5 V to ensure a low state.
§ Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
¶ 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
