DESCRIPTION/ORDERING INFORMATION  
The SN74LVC1G123 is a single retriggerable monostable multivibrator designed for 1.65-V to 5.5-V VCC  
operation.  
This monostable multivibrator features output pulse-duration control by three methods. In the first method, the A  
input is low, and the B input goes high. In the second method, the B input is high, and the A input goes low. In  
the third method, the A input is low, the B input is high, and the clear (CLR) input goes high.

(1) Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at  
www.ti.com/sc/package.  
(2) DCT: The actual top-side marking has three additional characters that designate the year, month, and assembly/test site.  
DCU: The actual top-side marking has one additional character that designates the assembly/test site.  
YEP/YZP: The actual top-side marking has three preceding characters to denote year, month, and sequence code, and one following  
character to designate the assembly/test site. Pin 1 identifier indicates solder-bump composition (1 = SnPb, = Pb-free).
