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.

HD74AC123A
Dual Retriggerable Resettable Multivibrator
ADE-205-365 (Z)
1st. Edition
Sep. 2000
Description
Each half of the HD74AC123A features retriggerable capability, complementary dc level triggering and
overriding Direct Clear. When a circuit is in the quasi-stable (delay) state, another trigger applied to the
inputs (per the Truth Table) will cause the delay period to start again, without disturbing the outputs. By
repeating this process, the output pulse period (Q High, Q Low) can be made as long as desired.
Alternatively, a delay period can be terminated at any time by a Low signal on CD, which also inhibits
triggering. An internal connection from CD to the input gate makes it possible to trigger the circuit by a
positive-going signal on CD, as shown in the Truth Table. For timing capacitor values greater than 1000
pF, the output pulse width is defined as follows.
Where tw is in ns, RX is in kΩ and CX is in pF.
tw = RXCX
