Frequently Asked Questions
What type of logic function does the SN74S157NSRG4 perform?
The SN74S157NSRG4 is a quad 2-to-1 data multiplexer, meaning it contains four independent multiplexer sections each selecting one of two data inputs based on a single shared SELECT control line. Output polarity is true (non-inverting).
What logic family does the SN74S157NSRG4 belong to?
This device belongs to the 74S (Schottky TTL) logic family, which offers higher switching speeds compared to standard 74LS devices. The Schottky clamping reduces saturation delays, making it well suited for high-frequency data path applications.
What package does the SN74S157NSRG4 come in?
The SN74S157NSRG4 is housed in a 16-pin SOIC (SOP-16) surface-mount package. This narrow-body package is compact and widely supported by automated PCB assembly processes, making it suitable for high-volume manufacturing.
What is the output current capability of the SN74S157NSRG4?
The SN74S157NSRG4 can sink a maximum of 20mA output low current (I_OL), and is rated for a 15pF load capacitance. These parameters define its fanout capability when driving standard TTL or CMOS inputs in multi-device bus architectures.
