The two sections of the device are controlled independently by Enable (E) and Output Enable (OE) control gates. The data on the D inputs is transferred to the latch outputs when the Enable (E) input is High. The latch remains transparent to the data input 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 high impedance “off” state, which means they will neither drive nor load the bus. The 74F534 is an 8-bit e...
