RD74LVC244B
Octal Buffers / Line Drivers with 3-state Outputs
Description
REJ03D0220–0200
Rev.2.00
Feb. 17, 2005
The RD74LVC244B has eight line drivers with three state outputs in a 20 pin package. This device is a non-inverting
buffer and has two active low enables (1G and 2G). 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
• V_CC = 1.65 V to 5.5 V
• All inputs V_IH (Max.) = 5.5 V (@V_CC = 0 V to 5.5 V)
• All outputs V_OUT (Max.) = 5.5 V (@V_CC = 0 V or output off state)
• Typical V_OL ground bounce < 0.8 V (@V_CC = 3.3 V, Ta = 25°C)
• Typical V_OH undershoot > 2.0 V (@V_CC = 3.3 V, Ta = 25°C)
• High output current ±4 mA (@V_CC = 1.65 V)
±8 mA (@V_CC = 2.3 V)
±12 mA (@V_CC = 2.7 V)
±24 mA (@V_CC = 3.0 V to 5.5 V)
