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.

HD74LVCR2245A
Octal Bidirectional Transceivers with 3state Outputs
ADE-205-235B (Z) 3rd. Edition January 2001 Description
The HD74LVCR2245A 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. All outputs, which are designed to sink up to 12 mA, include equivalent 26 resistors to reduce overshoot and undreshoot. Low voltage and high speed operation is suitable at battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation.
Features
· VCC = 1.65 to 5.5 V · All inputs VIH (Max) = 5.5 V (@VCC = 0 to 5.5 V) · All inputs / outputs VI / O (Max) = 5.5 V (@VCC = 0 V or output off state) · Typical VOL ground bounce 2.0 V (@VCC = 3.3 V, Ta = 25°C) · High output current ±12 mA (@VCC = 3.0 to 5.5 V) · All outputs have equivalent 26 series resistors, so no external resistors are required
