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 VI 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.
