Latch-Up Performance Exceeds 250 mA Per
JESD 17
Bus Hold on Data Inputs Eliminates the Need
for External Pullup/Pulldown Resistors
Package Options Include Plastic 300-mil
Shrink Small-Outline (DL) and Thin Shrink
Small-Outline (DGG) Packages
NOTE: For tape-and-reel order entry, the DGGR package is
abbreviated to GR.
This 20-bit bus-interface D-type latch is designed for
1.65-V to 3.6-V VCC operation.
The SN74ALVCH162841 features 3-state outputs
designed specifically for driving highly capacitive or
relatively
low-impedance
loads.
This
device
is
particularly suitable for implementing buffer registers,
unidirectional bus drivers, and working registers.
The SN74ALVCH162841 can be used as two 10-bit
latches or one 20-bit latch. The 20-bit latch is a
transparent D-type latch. The device has noninverting
data (D) inputs and provides true data at its outputs.
While the latch-enable (1LE or 2LE) input is high, the
Q outputs of the corresponding 10-bit latch follow the
D inputs. When LE is taken low, the Q outputs are
latched at the levels set up at the D inputs.
<br/>
A buffered output-enable (1OE or 2OE) input can be used to place the outputs of the corresponding 10-bit latch
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 bus lines significantly.
OE does not affect the internal operation of the latches. Old data can be retained or new data can be entered
while the outputs are in the high-impedance state.
The outputs, which are designed to sink up to 12 mA, include equivalent 26-
resistors to reduce overshoot and
undershoot.
