HD74lVC16244A

HD74LVC16244A 16-bit Buffers / Line Drivers with 3-state Outputs ADE-205-119B(Z) 3rd Edition Decemver 1996 Description The HD74LVC16244A has sixteen line drivers with three state outputs in a 48 pin package. This device is a non inverting buffer and has two active low enables (1 G to 4G). Each enable independently controls four buffers. Low voltage and high speed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation. Features VCC = 2.0 V to 5.5 V All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VOUT (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 output current ±24 mA (@VCC = 3.0 V to 5.5 V) Function Table Inputs G H L L H: L: X: Z: High level Low level Immaterial High impedance A X H L Output Y Z H L HD74LVC16244A 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 32 3A4 31 VCC 30 4A1 29 4A2 28 GND 27 4A3 26 4A4 25 3G (Top view) 2 HD74LVC16244A Absolute Maximum Ratings Item Supply voltage Input diode current Input voltage Output diode current Symbol VCC I IK VI I OK Ratings –0.5 to 6.0 ...
