Description

The 74ABT16373B high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and  high output drive.

The 74ABT16373B device is a dual octal transparent latch coupled to two sets of eight 3-State output  buffers. The two sections of the device are controlled independently by Enable (nE) and Output Enable (nOE) control gates.

The data of the 74ABT16373B on each set of D inputs are transferred to  the latch outputs when the Latch Enable (nE) input is High. The latch remains transparent to the data inputs while nE is High, and stores the data that is present one setup time before the High-to-Low enable transition.

The 3-State output buffers of the 74ABT16373B are designed to drive heavily loaded 3-State buses, MOS memories, or MOS microprocessors. Each active-Low Output Enable (nOE) controls eight 3-State buffers independent of the latch operation.
