The SN54ABT841 and SN74ABT841A 10-bit  
latches are 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.

The ten transparent D-type latches provide true  
data at their outputs.

A buffered output-enable (OE) input can be used  
to place the ten outputs in either a normal logic  
state (high or low logic levels) or  
a
NC – No internal connection  
high-impedance state. In the high-impedance  
state, the outputs neither load nor drive the bus  
lines significantly. The high-impedance state and  
increased drive provide the capability to drive bus  
lines without need for interface or pullup  
components.  
OE does not affect the internal operations of the latch. Previously stored 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.

However, to ensure the high-impedance state above 2.1 V, OE should be tied to V

The SN54ABT841 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74ABT841A is characterized for operation from –40°C to 85°C.
