The ’AHC367 devices are hex buffers and line
drivers designed for 2-V to 5.5-V V operation.
CC
These devices are designed specifically to
improve both the performance and density of
3-state memory address drivers, clock drivers,
and bus-oriented receivers and transmitters. The
’AHC367 devices are organized as dual 4-line
and 2-line buffers/drivers with active-low
output-enable (1OE and 2OE) inputs. When OE is
low, the device passes noninverted data from the
A inputs to the Y outputs. When OE is high, the
outputs are in the high-impedance state.

To ensure the high-impedance state during power
up or power down, OE should be tied to V
CC
through a pullup resistor; the minimum value of
the resistor is determined by the current-sinking
capability of the driver.

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.
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51-7.

(1) 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.

Eco Plan
-
The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS
&
no Sb/Br)
-
please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
