DESCRIPTION
The 74ABT16273 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.
This part is a 16-bit edge triggered D-type flip-flop with non-inverting high drive outputs. This device can be used as two 8-bit flip-flops or one 16-bit flip-flop. When the clock (CP) goes High, the data on the D inputs is stored and the Q outputs display the stored data.
This device also features a master reset (MR flip-flops to the Low state when MR
is set to the Low state.
Two options are available, 74ABT16273 which does not have the bus-hold feature and 74ABTH16273 which incorporates the bus-hold feature.
