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.

HD74HC299

8-bit Universal Shift/Storage Register (with 3-state outputs)

ADE-205-488 (Z)

1st. Edition

Sep. 2000

Description

The HD74HC299 features multiplexed inputs/outputs to achieve full 8-bit data handling in a single 20-pin

package. Due to the large output drive capability and 3-state feature, this device is ideally suited for

interfacing with bus lines in a bus oriented system. Two function select inputs and two output control

inputs are used to choose the mode of operation as listed in the function table. Synchronous parallel

loading is accomplished by taking both function select lines S and S₁high. This places the 3-state outputs

in a high impedance state, which permits data applied to the input/output lines to be clocked into the

overriding clear input is provided to clear the register whether the outputs are enabled or disabled.

Features

High Speed Operation

High Output Current: Fanout of 15 LSTTL Loads

Wide Operating Voltage: V_CC= 2 to 6 V

Low Input Current: 1 µA max

Low Quiescent Supply Current: I_CC(static) = 4 µA max (Ta = 25°C)
