HD74LVCZ16244A Datasheet | Hitachi Semiconductor

Description The HD74LVCZ16244A has sixteen line drivers with three state outputs in a 48 pin package. This device is a non inverting buffer and has four active low enables (1 G 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 puter) 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 m A (@V CC = 3.0 to 5.5 V) Function Table Inputs G H L L H : High level L : Low level X : Immaterial Z : High impedance A X H L Z H L Output Y 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) Absolute Maximum Ratings Item Supply voltage Input voltage Output voltage Symbol VCC VI VO Ratings - 0.5 to 7.0 - 0.5 to 7.0 - 0.5 to 7.0 - 0.5 to VCC+0.5 Input diode current Output diode current Output current VCC, GND current Storage temperature I IK I OK IO I CC or IGND Tstg - 50 - 50 ±50 ±100 - 65 to 150 m A m A m A m A °C Unit V V V Output “Z” or VCC : OFF Output “H” or “L” VI < 0 VO < 0 Conditions Note: The absolute maximum ratings are values which must not individually be exceeded, and furthermore, no two of which may be...
