The two sections of the 2Q4 2D4 19 30 device are controlled independently by Enable (nE) and Output 2Q5 20 29 2D5 Enable (nOE) control gates. 21 28 GND GND The data on each set of D inputs are transferred to the latch outputs 2Q6 22 27 2D6 when the Latch Enable (nE) input is HIGH. The latch remains 23 26 2Q7 2D7 transparent to the data inputs while nE is HIGH, and stores the data 24 25 2OE 2E that is present one set-up time before the HIGH-to-LOW enable transition. SA00379 The 3-State output buffers 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. When nOE is LOW, the latched or transparent data appears at the outputs. When nOE is HIGH, the outputs are in the high-impedance OFF state, which means they will neither drive nor load the bus.
