DESCRIPTION/ORDERING INFORMATION  
This 16-bit edge-triggered D-type flip-flop is designed  
for 1.65-V to 3.6-V VCC operation.  
The SN74ALVCH162374 is particularly suitable for  
implementing buffer registers, I/O ports, bidirectional  
bus drivers, and working registers. It can be used as  
two 8-bit flip-flops or one 16-bit flip-flop. On the  
positive transition of the clock (CLK) input, the Q  
outputs of the flip-flop take on the logic levels set up  
at the data (D) inputs.

2OE  
The output-enable (OE) input can be used to place  
the eight outputs in either a normal logic state (high  
or low logic levels) or a high-impedance state. In the  
high-impedance state, the outputs neither load nor  
drive the bus lines 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 flip-flop. 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.
