RD74LVC245B
Octal Bidirectional Transceivers with 3-state Outputs
REJ03D0386鈥?100
Rev.1.00
Aug. 26, 2004
Description
The RD74LVC245B has eight buffers with three state outputs in a 20 pin package. When (DIR) is high, data flows
from the A inputs to the B outputs, and when (DIR) is low, data flows from the B inputs to the A outputs. A and B bus
are separated by making enable input (OE) high level. 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.
