HD74ALVCHS162830 1-bit to 2-bit Address Driver with 3-state Outputs ADE-205-221 (Z) Preliminary 1st. Edition July 1998 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, OE should be tied to V CC 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. All outputs, which are designed to sink up to 12 mA, include equivalent 26 Ω resistors to reduce overshoot and undreshoot. Diodes to VCC have been added on the inputs to clamp overshoot. 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 ±12 mA (@VCC = 3.0 V) • Bus hold on data inputs eliminates the need for external pullup / pulldown resistors • All outputs have equivalent 26 Ω series resistors, so no external resistors are required • Diode on inputs clamp overshoot HD74ALVCHS162830 Function Table Inputs Outputs OE1 OE2 A 1Yn 2Yn L H H H Z L H L L Z H L H Z H H L L Z L L L H H H L L L L L H H X Z Z H : High level L : Low level X : Immaterial Z : High impedance 2 HD74ALVCHS162830 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 1Y7 2Y7 VCC 1Y8 2Y8 GND 1Y9 2Y9 1Y10 2Y10 GND 1Y11 2Y11 VCC 1Y12 2Y12 GND 1Y13 2Y13 GND 1Y14 2Y14 VCC 1Y15 2Y15 GND 1Y16 2Y16 (Top view) 3 HD74ALVCHS162830 Absolute Maximum Ratings Item Symbol Ratings Unit VCC –0.5 to 4.6 V VI –0.5 to 4.6 V VO –0.5 to VCC +0.5 V Input clamp current I IK –50 mA VI < 0 Output clamp current I OK ±50 mA VO < 0 or VO > VCC Continuous output current IO ±50 mA VO = 0 to VCC VCC, GND current / pin I CC or IGND ±100 mA Maximum power dissipation at Ta = 55°C (in still air) *3 PT 1 W Storage temperature Tstg –65 to 150 °C Supply voltage Input voltage *1 Output voltage Notes: *1, 2 Conditions TVSOP Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability. 1. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed. 2. This value is limited to 4.6 V maximum. 3. The maximum package power dissipation is calculated using a junction temperature of 150°C and a board trace length of 750 mils.
