Frequently Asked Questions
How many data inputs does the SN74ALS153DR have per channel?
The SN74ALS153DR has four data inputs (I0–I3) per channel, and two common address inputs (A and B) select which of the four inputs is routed to the output. With two independent channels in one package, the device can simultaneously select from two independent groups of four data sources using shared address lines.
What logic family does the SN74ALS153DR belong to?
The SN74ALS153DR belongs to the ALS (Advanced Low-power Schottky) TTL logic family. ALS provides faster switching speed than standard LS-TTL while consuming less power than FAST-TTL, making it a good choice for designs where both speed and power efficiency matter in 5V digital systems.
Does the SN74ALS153DR have individual enable pins?
Yes, each of the two 4-to-1 multiplexer channels in the SN74ALS153DR has its own individual active-low enable (Ea and Eb) input pin. When the enable pin is asserted low, the selected data input is routed to the output. When deasserted high, the output is forced low, allowing the two channels to be independently enabled or disabled.
What package is the SN74ALS153DR offered in?
The SN74ALS153DR is housed in a 16-pin SOIC (Small Outline IC) package with DR suffix indicating tape-and-reel packaging. This makes it compatible with standard SMT pick-and-place equipment for high-volume automated board assembly, with a compact footprint matching standard SOIC-16 PCB land patterns.
