description
The ’ABT16373A are 16-bit transparent D-type
latches with 3-state outputs designed specifically
for driving highly capacitive or relatively
low-impedance loads. They are particularly
suitable for implementing buffer registers, I/O
ports, bidirectional bus drivers, and working
registers.
These devices 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 a high-impedance state. In the high-impedance state, the outputs neither load nor drive
the bus lines 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.
When V
is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.
CC
However, to ensure the high-impedance state above 2.1 V, OE should be tied to V
the minimum value of the resistor is determined by the current-sinking capability of the driver.
through a pullup resistor;
CC
The SN54ABT16373A is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74ABT16373A is characterized for operation from –40°C to 85°C.

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.

-
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
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
