DESCRIPTION/ORDERING INFORMATION
This 16-bit transparent D-type latch is designed for
1.65-V to 3.6-V VCC operation.
The SN74ALVCH16373 is particularly suitable for
implementing buffer registers, I/O ports, bidirectional
bus drivers, and working registers. This device can
be used as two 8-bit latches or one 16-bit latch.
When the latch-enable (LE) input is high, the Q
outputs follow the data (D) inputs. When LE is taken
low, the Q outputs are latched at the levels set up at
the D inputs.

A buffered output-enable (OE) input can be used to
place the eight outputs in either a normal logic state
(high or low logic levels) or the high-impedance state.
In the high-impedance state, the outputs neither
load nor drive the buslines significantly. The
high-impedance state and the increased drive provide
the capability to drive bus lines without need for
interface or pullup components. OE does not affect
internal operations of the latch. Old data can be
retained or new data can be entered while 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 VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors
with the bus-hold circuitry is not recommended.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

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 negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
This value is limited to 4.6 V maximum.
The package thermal impedance is calculated in accordance with JESD 51-7.
