The 74ABT373A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.
The 74ABT373A device is an octal transparent latch coupled to eight 3-State output buffers. The two sections of the device are controlled independently by Enable (E) and Output Enable (OE) control gates.
The data on the D inputs are transferred to the latch outputs when the Latch Enable (E) input is High. The latch remains transparent to the data inputs while E is High, and stores the data that is present one setup time before the High-to-Low enable transition.
The 3-State output buffers are designed to drive heavily loaded 3-State buses, MOS memories, or MOS microprocessors. The active-Low Output Enable (OE) controls all eight 3-State buffers independent of the latch operation.
When OE is Low, the latched or transparent data appears at the outputs. When OE is High, the outputs are in the High-impedance 'OFF' state, which means they will neither drive nor load the bus.
