description  
This 20-bit bus-interface D-type latch is designed  
for 1.65-V to 3.6-V V operation.  
CC  
The SN74ALVCH16841 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.

2LE  
TheSN74ALVCH16841 can be used as two 10-bit  
latches or one 20-bit latch. The 20 latches are  
transparent D-type latches. 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.  
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.  
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.  
The SN74ALVCH16841 is characterized for operation from –40°C to 85°C.
