HD74ALVCH16830

HD74ALVCH16830 1-bit to 2-bit Address Driver with 3-state Outputs ADE-205-196 (Z) 1st. Edition February 2000 Description This 1-bit to 2-bit address driver is designed for 2.3 V to 3.6 V V CC operation. To ensure the high impedance state during power up or power down, the output ebable (OE ) input 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. Active bus hold circuitry is provided to hold unused or floating inputs at a valid logic level. Features VCC = 2.3 V to 3.6 V Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C) High output current ±24 mA (@V CC = 3.0 V) Bus hold on data inputs eliminates the need for external pullup / pulldown resistors HD74ALVCH16830 Function Table Inputs OE1 L L H H L L H H : High level L : Low level X : Immaterial Z : High impedance OE2 H H L L L L H A H L H L H L X Outputs 1Yn H L Z Z H L Z 2Yn Z Z H L H L Z 2 HD74ALVCH16830 Pin Arrangement 2Y2 1Y2 GND 2Y1 1Y1 VCC A1 A2 GND A3 A4 GND A5 A6 VCC A7 A8 GND A9 OE1 OE2 A10 GND A11 A12 VCC A13 A14 GND A15 A16 GND A17 A18 VCC 2Y18 1Y18 GND 2Y17 1Y17 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 1Y3 2Y3 GND 1Y4 2Y4 VCC 1Y5 2Y5 GND 1Y6 2Y6 GND 1Y...
