† All typical values are at VCC = 3.3 V, TA = 25°C.
‡ The bus-hold circuit can sink at least the minimum low sustaining current at VIL max. IBHLshould be measured after lowering VIN to GND and
then raising it to VIL max.
§ The bus-hold circuit can source at least the minimum high sustaining current at VIH min. IBHH should be measured after raising VIN to VCC and
then lowering it to VIH min.
¶ An external driver must source at least IBHLO to switch this node from low to high.
# An external driver must sink at least IBHHO to switch this node from high to low.
|| Current into an output in the high state when VO > VCC
k High-impedance state during power up or power down
h This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
