MC74LCX16374/D
MC74LCX16374
Low-Voltage CMOS 16-Bit
D-Type Flip-Flop
With 5 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
The MC74LCX16374 is a high performance, non−inverting 16−bit
D−type flip−flop operating from a 2.3 V to 3.6 V supply. The device is
byte controlled. Each byte has separate Output Enable and Clock Pulse
inputs. These control pins can be tied together for full 16−bit operation.
High impedance TTL compatible inputs significantly reduce current
loading to input drivers while TTL compatible outputs offer improved
switching noise performance. A V
I
specification of 5.5 V allows
MC74LCX16374 inputs to be safely driven from 5.0 V devices.
The MC74LCX16374 consists of 16 edge−triggered flip−flops with
individual D−type inputs and 5.0 V−tolerant 3−state true outputs. The
buffered clocks (CPn) and buffered 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.
