RD74LVC16244B
16-bit Buffers / Line Drivers with 3-state Outputs
REJ03D0527–0100
Rev.1.00
Mar. 14, 2005
Description
The RD74LVC16244B 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 (1
G 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.
