HD74LVCZ16244A
16-bit Buffers / Line Drivers with 3-state Outputs
REJ03D0374-0200 (Previous ADE-205-232 (Z)) Rev.2.00 Aug. 19, 2004
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 (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 = 25C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25C) High impedance state during power up and power down Power off disables outputs, permitting live insertion High output current 24 mA (@VCC = 3.0 to 5.5 V) Ordering Information
