The DM4022 is a high speed T-type flip flop. DM4022 is suitable for very high speed and complex digital applications such as duobinary precoding, counter implementation, and clock divider. The device consists of a master-slave latch designed using an ECL topology to guarantee high speed operation. Differential Input is on-chip DC coupled and terminated with 50 Ohm resistors to ground. The differential data outputs should DC or AC terminated off chip with 50 Ohm resistors to ground. DM4022 operates from a single -3.3 V power supply.
