They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. 1 48 2 47 3 46 4 45 5 44 6 43 7 42 8 41 9 40 10 39 11 38 12 37 13 36 14 35 15 34 16 33 17 32 18 31 19 30 20 29 21 28 22 27 23 26 24 25 1CLK 1D1 1D2 GND 1D3 1D4 VCC 1D5 1D6 GND 1D7 1D8 2D1 2D2 GND 2D3 2D4 VCC 2D5 2D6 GND 2D7 2D8 2CLK The ’AC16374 can be used as two 8-bit flip-flops or one 16-bit flip-flop. On the positive transition of the clock (CLK) input, the Q outputs of the flip-flop take on the logic levels set up at the data (D) inputs. A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. OE does not affect the internal operations of the flip-flop. Old data can be retained or new data can be entered while the outputs are in the high-impedance state. The 74AC16374 is packaged in TI’s shrink small-outline package, which provides twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area. The 54AC16374 is characterized for operation over the full military temperature range of –55°C to 125°C. The 74AC16374 is characterized for operation from –40°C to 85°C.
