Octal Buffers / Line Drivers with 3-state Outputs
REJ03D0220鈥?200
Rev.2.00
Feb. 17, 2005
Description
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.
