This 18-bit bus-interface D-type latch is designed  
for 1.65-V to 3.6-V V operation.  
CC  
The SN74ALVCH16843 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.  
This device can be used as two 9-bit latches or  
one 18-bit latch. The 18 latches are transparent  
D-type latches. The device has noninverting data  
(D) inputs and provides true data at its outputs.

A buffered output-enable (OE) input can be used  
to place the nine outputs in either a normal logic  
state (high or low logic levels) or the  
high-impedance state. The outputs also are in the  
high-impedance state during power-up and  
power-downconditions. Theoutputsremaininthe  
high-impedance state while the device is powered  
down. 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.  
The output-enable (OE) input 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.  
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 inputs at a valid logic level.  
The SN74ALVCH16843 is characterized for operation from –40°C to 85°C.
