The device is ideal for use in applications in which a single address bus is driving four separate memory locations. The SN74ALVC162831 can be used as a buffer or a register, depending on the logic level of the select (SEL) input. When SEL is logic high, the device is in the buffer mode. The outputs follow the inputs and are controlled by the two output-enable (OE) inputs. Each OE controls two groups of nine outputs. When SEL is logic low, the device is in the register mode. The register is an edge-triggered D-type flip-flop. On the positive transition of the clock (CLK) input, data set up at the A inputs is stored in the internal registers. OE controls operate the same as in buffer mode. When OE is logic low, the outputs are in a normal logic state (high or low logic level). When OE is logic high, the outputs are in the high-impedance state. SEL and OE do not affect the internal operation of the flip-flops. Old data can be retained or new data can be entered while the outputs are in the high-impedance state. 1 80 2 79 3 78 4 77 5 76 6 75 7 74 8 73 9 72 10 71 11 70 12 69 13 68 14 67 15 66 16 65 17 64 18 63 19 62 20 61 21 60 22 59 23 58 24 57 25 56 26 55 27 54 28 53 29 52 30 51 31 50 32 49 33 48 34 47 35 46 36 45 37 44 38 43 39 42 40 41 1Y2 2Y2 GND 3Y2 4Y2 VCC 1Y3 2Y3 GND 3Y3 4Y3 GND 1Y4 2Y4 VCC 3Y4 4Y4 GND 1Y5 2Y5 3Y5 4Y5 GND 1Y6 2Y6 VCC 3Y6 4Y6 GND 1Y7 2Y7 GND 3Y7 4Y7 VCC 1Y8 2Y8 GND 3Y8 4Y8 NC – No internal connection Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. The SN74ALVC162831 is characterized for operation from –40°C to 85°C.
