74VCX16374
Low-Voltage 1.8/2.5/3.3V
16-Bit D-Type Flip-Flop
With 3.6V鈥揟olerant Inputs and Outputs
(3鈥揝tate, Non鈥揑nverting)
The 74VCX16374 is an advanced performance, non鈥搃nverting
16鈥揵it D鈥搕ype flip鈥揻lop. It is designed for very high鈥搒peed, very
low鈥損ower 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鈥揵it
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鈥搗oltage tolerant to 3.6V.
The 74VCX16374 consists of 16 edge鈥搕riggered flip鈥揻lops with
individual D鈥搕ype inputs and 3.6V鈥搕olerant 3鈥搒tate outputs. The
clocks (CPn) and Output Enables (OEn) are common to all flip鈥揻lops
within the respective byte. The flip鈥揻lops will store the state of
individual D inputs that meet the setup and hold time requirements on
the LOW鈥搕o鈥揌IGH Clock (CP) transition. With the OE LOW, the
contents of the flip鈥揻lops 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鈥揻lops.
