74VCX16374  
Low-Voltage 1.8/2.5/3.3V  
16-Bit D-Type Flip-Flop  
With 3.6V–Tolerant Inputs and Outputs  
(3–State, Non–Inverting)  
The 74VCX16374 is an advanced performance, non–inverting  
16–bit D–type flip–flop. It is designed for very high–speed, very  
low–power operation in 1.8V, 2.5V or 3.3V systems. The VCX16374  
is byte controlled, with each byte functioning identically, but  
independently. Each byte has separate Output Enable and Clock Pulse  
inputs. These control pins can be tied together for a full 16–bit  
operation.  
When operating at 2.5V (or 1.8V) the part is designed to tolerate  
voltages it may encounter on either inputs or outputs when interfacing  
to 3.3V busses. It is guaranteed to be over–voltage tolerant to 3.6V.  
The 74VCX16374 consists of 16 edge–triggered flip–flops with  
individual D–type inputs and 3.6V–tolerant 3–state outputs. The  
clocks (CPn) and Output Enables (OEn) are common to all flip–flops  
within the respective byte. The flip–flops will store the state of  
individual D inputs that meet the setup and hold time requirements on  
the LOW–to–HIGH Clock (CP) transition. With the OE LOW, the  
contents of the flip–flops are available at the outputs. When the OE is  
HIGH, the outputs go to the high impedance state. The OE input level  
does not affect the operation of the flip–flops.
