MC74LCX16374: Low Voltage CMOS 16-Bit D Flip-Flop

The MC74LCX16374 is a high performance, non-inverting 16-bit D-type flip-flop operating from a 2.3 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 (OEnbar) 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 theLOW-to-HIGH Clock (CP) transition. With the OEbar LOW, the contents ofthe flip-flops are available at the outputs. When the OEbar is HIGH, the outputs go to the high impedance state. The OEbar input level does not affect the operation of the flip-flops.
