74VCX16374
Low−Voltage 1.8/2.5/3.3V
16−Bit D−Type Flip−Flop
With 3.6 V−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 1.8 V, 2.5 V or 3.3 V 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 2.5 V (or 1.8 V) the part is designed to tolerate
voltages it may encounter on either inputs or outputs when interfacing
to 3.3 V busses. It is guaranteed to be overvoltage tolerant to 3.6 V.
The 74VCX16374 consists of 16 edge−triggered flip−flops with
individual D−type inputs and 3.6 V−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.
