DESCRIPTION/ORDERING INFORMATION  
This 16-bit transparent D-type latch is designed for  
1.65-V to 3.6-V VCC operation.

The SN74ALVCH16373 is particularly suitable for  
implementing buffer registers, I/O ports, bidirectional  
bus drivers, and working registers. This 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 the high-impedance state.  
In the high-impedance state, the outputs neither  
load nor drive the buslines significantly. The  
high-impedance state and the increased drive provide  
the capability to drive bus lines without need for  
interface or pullup components. 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.  
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors  
with the bus-hold circuitry is not recommended.
