To all our customers
Regarding the change of names mentioned in the document, such as Hitachi
Electric and Hitachi XX, to Renesas Technology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand
names are mentioned in the document, these names have in fact all been changed to Renesas
Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and
corporate statement, no changes whatsoever have been made to the contents of the document, and
these changes do not constitute any alteration to the contents of the document itself.

Cautions
Keep safety first in your circuit designs!
1. Renesas Technology Corporation puts the maximum effort into making semiconductor products better
and more reliable, but there is always the possibility that trouble may occur with them. Trouble with
semiconductors may lead to personal injury, fire or property damage.
Remember to give due consideration to safety when making your circuit designs, with appropriate
measures such as (i) placement of substitutive, auxiliary circuits, (ii) use of nonflammable material or
(iii) prevention against any malfunction or mishap.
Notes regarding these materials
1. These materials are intended as a reference to assist our customers in the selection of the Renesas
Technology Corporation product best suited to the customer's application; they do not convey any
license under any intellectual property rights, or any other rights, belonging to Renesas Technology
Corporation or a third party.

HD74LV245A
Octal Bus Transceivers with 3-state Outputs
ADE-205-247A (Z)
2nd. Edition
Jul. 2001
Description
The HD74LV245A has eight buffers with three-state outputs in a 20-pin package. When DIR is high, data
is transferred from the A inputs to the B outputs, and when DIR is low, data is transferred from the B
inputs to the A outputs. The A and B buses are separated by making the enable input (OE) high level.
Low-voltage operation is suitable for battery-powered products (e.g., notebook computers), and the low
power consumption extends the battery life.

Notes: The absolute maximum ratings are values which must not individually be exceeded, and
furthermore, no two of which may be realized at the same time..
1. The input and output voltage ratings may be exceeded even if the input and output clamp-
current ratings are observed.
2. This value is limited to 5.5 V maximum.
3. The data above are measured by ∆VBE method mounting on glass epoxy board (40 × 40 × 1.6
mm) with 10% of wiring density.
