description  
This 32-bit edge-triggered D-type flip-flop is designed for 1.65-V to 3.6-V V  
operation.  
CC  
The SN74LVCH32374A is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus  
drivers, and working registers. It can be used as four 8-bit flip-flops, two 16-bit flip-flops, or one 32-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.  
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  
thebuslinessignificantly. Thehigh-impedancestateandincreaseddriveprovidethecapabilitytodrivebuslines  
without 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.  
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.  
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators  
in a mixed 3.3-V/5-V system environment.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.  
The SN74LVCH32374A is characterized for operation from –40°C to 85°C.
