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 (1G 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)
