description
This 24-bit to 12-bit multiplexer is designed for
2.7-V to 3.6-V V
CC
operation.
This device is designed to multiplex signals from
24-bit data sources to 12-output data lines in
bus-organized systems. The 3-state outputs will
not load the data lines when the output-enable
(OE) input is at a high logic level.
The SN74ALVC16258 is available in TI’s shrink small-outline (DL) and thin shrink small-outline (DGG)
packages, which provide twice the I/O pin count and functionality of standard small-outline packages in the same
printed-circuit-board area.
The 74ALVC16258 is characterized for operation from – 40
°
C to 85
°
C.
