SCBS093L – DECEMBER 1993 – REVISED DECEMBER 2006
DESCRIPTION/ORDERING INFORMATION (CONTINUED)
The 3-state control gate is a two-input AND gate with active-low inputs so that if either output-enable (OE1 or
OE2) input is high, all eight outputs are in the high-impedance state.
When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 2.1 V, OE should be tied to VCC through a pullup resistor;
the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54ABT541 is characterized for operation over the full military temperature range of –55°C to 125°C. The
SN74ABT541B is characterized for operation from –40°C to 85°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating
conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace length
of zero.

All typical values are at VCC = 5 V.
On products compliant to MIL-PRF-38535, this parameter does not apply.
On products compliant to MIL-PRF-38535, this parameter is not production tested.
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.

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
