description  
The  
’AHCT16374  
devices  
are  
16-bit  
edge-triggered D-type flip-flops with 3-state  
outputs 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.  
These devices 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 at the data (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 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.  
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.  
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 SN54AHCT16374 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74AHCT16374 is characterized for operation from –40°C to 85°C.
