MC74LCX16374/D
MC74LCX16374
Low-Voltage CMOS 16-Bit
D-Type Flip-Flop
With 5 VTolerant Inputs and Outputs
(3State, NonInverting)
The MC74LCX16374 is a high performance, noninverting 16bit
Dtype flipflop 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 16bit 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 edgetriggered flipflops with
individual Dtype inputs and 5.0 Vtolerant 3state true outputs. The
buffered clocks (CPn) and buffered Output Enables (OEn) are common
to all flipflops within the respective byte. The flipflops will store the
state of individual D inputs that meet the setup and hold time
requirements on the LOWtoHIGH Clock (CP) transition. With the
OE LOW, the contents of the flipflops 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 flipflops.
