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

HD74LVC245A

Octal Bidirectional Transceivers with 3-state Outputs

ADE-205-111B(Z)

3rd Edition

December 1996

Description

The HD74LVC245A has eight buffers with three state outputs in a 20 pin package. When (T / R) is high,

data flows from the A inputs to the B outputs, and when (T / R) 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.

Features

•

V_CC= 2.0 V to 5.5 V

All inputs V_IH(Max.) = 5.5 V (@V_CC= 0 V to 5.5 V)

All input outputs V_I/O(Max.) = 5.5 V (@V_CC= 0 V or output off state)

Typical V_OLground bounce < 0.8 V (@V_CC= 3.3 V, Ta = 25°C)

Typical V_OHundershoot > 2.0 V (@V_CC= 3.3 V, Ta = 25°C)

High output current 24 mA (@V_CC= 3.0 V to 5.5 V)
