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 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 set-up time before the HIGH-to-LOW enable transition. 1OE 1 48 1E 1Q0 2 47 1D0 1Q1 3 46 1D1 GND 4 45 GND 1Q2 5 44 1D2 1Q3 6 43 1D3 VCC 7 42 VCC 1Q4 8 41 1D4 1Q5 9 40 1D5 GND 10 39 GND 1Q6 11 38 1D6 1Q7 12 37 1D7 2Q0 13 36 2D0 2Q1 14 35 2D1 GND 15 34 GND 2Q2 16 33 2D2 2Q3 17 32 2D3 VCC 18 31 VCC 2Q4 19 30 2D4 2Q5 20 29 2D5 GND 21 28 GND 2Q6 22 27 2D6 2Q7 23 26 2D7 2OE 24 25 2E 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.
