HD74LVCZ16240A

HD74LVCZ16240A 16–bit Buffers / Line Drivers with 3–state Outputs ADE-205-231 (Z) 1st. Edition February 1999 Description The HD74LVCZ16240A has sixteen inverter drivers with three state outputs in a 48 pin package. This device is a inverting buffer and has four active low enables (1G to 4G ). Each enable independently controls four buffers. When VCC is between 0 and 1.5 V, the device is in the high impedance state during power up or power down. Low voltage and high speed operation is suitable at battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation. Features VCC = 2.7 to 5.5 V All inputs VIH (Max) = 5.5 V (@VCC = 0 to 5.5 V) All outputs VO (Max) = 5.5 V (@VCC = 0 V or output off state) 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 impedance state during power up and power down Power off disables outputs, permitting live insertion High output current ±24 mA (@V CC = 3.0 to 5.5 V) HD74LVCZ16240A Function Table Inputs G H L L H : High level L : Low level X : Immaterial Z : High impedance A X H L Z L H Output Y 2 HD74LVCZ16240A Pin Arrangement 1G 1 1Y1 2 1Y2 3 GND 4 1Y3 5 1Y4 6 VCC 7 2Y1 8 2Y2 9 GND 10 2Y3 11 2Y4 12 3Y1 13 3Y2 14 GND 15 3Y3 16 3Y4 17 VCC 18 4Y1 19 4Y2 20 GND 21 4Y3 22 4Y4 23 4G 24 48 2G 47 1A1 46 1A2 45 GND 44 1A3 43 1A4 42 VCC 41 2A1 40 2A2 39 GND 38 2A3 37 2A4 36 3A1 35 3A2 34 GND 33 3A3...
