RD74LVC245BTELL
RD74LVC245B Octal Bidirectional Transceivers with 3-state Outputs REJ03D0386–0100 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.
