74ABT573A
Datasheet
General description
The 74ABT573A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.
The 74ABT573A 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 74ABT573A is functionally identical to the 74ABT373 but has a flow-through pinout configuration to facilitate PC board layout and allow easy interface with microprocessors. 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.
