description
The
4ABT16373 is a 16-bit transparent D-type
latch with 3-state outputs designed specifically for
driving
highly
capacitive
or
relatively
low-impedance loads. It is particularly suitable for
implementing
buffer
registers,
I/O
ports,
bidirectional bus drivers, and working registers.
The 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 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
The output enable (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.
The SN74ABT16373 is available in TI’s shrink small-outline package (DL), which provides twice the I/O pin
count and functionality of standard small-outline packages in the same printed-circuit-board area.
The SN54ABT16373 is characterized for operation over the full military temperature range of 55
°C to 125°C.
The SN74ABT16373 is characterized for operation from 40
°C to 85°C.
