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

HD74CBT16212A
24-bit FET Bus-Exchange Switches
ADE-205-647A (Z)
Preliminary
Rev. 1
Feb. 2002
Description
The HD74CBT16212A devices provide 24-bits of high speed TTL-compatible bus switching or exchanging.
The low on state resistance of the switch allows connections to be made with minimal propagation delay.
Each device operates as a 24-bit bus switch or a 12-bit bus exchanger that provides data exchanging
between the four signal ports via the data-select (S0, S1, S2) terminals.
Features
Minimal propagation delay through the switch.
5 switch connection between two ports.
TTL-compatible input levels.
Ultra low quiescent power.
-Ideally suited for notebook applications.
