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.

HD74CBT3384A
10-bit FET Bus Switch
ADE-205-652 (Z)
Preliminary
Rev. 0
Jan. 2002
Description
The HD74CBT3384A provides ten bits of high-speed TTL-compatible bus switching. The low on-state
resistance of the switch allows connections to be made with minimal propagation delay.
The device is organized as two 5-bit switches with separate output-enable (OE) inputs. When
OE
is low,
the switch is on, and port A is connected to port B. When
OE
is high, the switch is open, and the high-
impedance state exists between the two ports.
Features
•
Minimal propagation delay through the switch.
•
5
Ω
switch connection between two ports.
•
TTL-compatible input levels.
•
Ultra low quiescent power.
-Ideally suited for notebook applications.

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. The maximum package power dissipation was calculated using a junction temperature of 150°C.
