MC74LCX16374

The MC74LCX16374 is a high performance, non–inverting 16–bit

D–type flip–flop operating from a 2.7 to 3.6V 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 VI specification of 5.5V allows

MC74LCX16374 inputs to be safely driven from 5V devices.

The MC74LCX16374 consists of 16 edge–triggered flip–flops with

individual D–type inputs and 5V–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.
