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 MC74VCX16374 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 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 MC74VCX16374 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.

4. These AC parameters are preliminary and may be modified prior to release. For CL = 50pF, add approximately 300ps to the AC maximum specification. 5. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The specification applies to any outputs switching in the same direction, either HIGH-to-LOW (tOSHL) or LOW-to-HIGH (tOSLH); parameter guaranteed by design.
