DESCRIPTION/ORDERING INFORMATION  
This 2-to-4 line decoder is designed for 1.65-V to 5.5-V VCC operation.  
The SN74LVC1G139 2-line to 4-line decoder is designed to be used in high-performance memory-decoding or  
data-routing applications requiring very short propagation delay times. In high-performance memory systems, this  
decoder can be used to minimize the effects of system decoding. When used with high-speed memories utilizing  
a fast enable circuit, the delay times of these decoders and the enable time of the memory usually are less than  
the typical access time of the memory. This means that the effective system delay introduced by the decoder is  
negligible.

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).
