Frequently Asked Questions
How many inputs does the SN74S151NSRE4 support?
The SN74S151NSRE4 is an 8-input multiplexer, meaning it can select one of eight data input lines and route it to the single output. Selection is controlled by a 3-bit binary address input (A, B, C), which provides 2^3 = 8 unique input selection states, covering all eight data inputs.
What logic family does the SN74S151NSRE4 belong to?
The SN74S151NSRE4 belongs to Texas Instruments' S-family (Schottky TTL) logic, which is known for high-speed switching performance compared to standard TTL. The S-family uses Schottky transistors to prevent saturation, reducing propagation delays and making it suitable for high-frequency digital circuit applications requiring fast multiplexer switching.
What is the output drive current of the SN74S151NSRE4?
The SN74S151NSRE4 provides a maximum output low current (IOL) of 20mA. This output drive capability allows it to sink sufficient current to drive standard TTL and CMOS logic gates connected to its output, including bus lines with multiple loads, without significant voltage degradation at the output low level.
What package does the SN74S151NSRE4 use?
The SN74S151NSRE4 is housed in a 16-pin SOP (Small Outline Package), identified by JESD-30 code R-PDSO-G16. This surface-mount plastic package is Pb-free and manufactured with green (halogen-free) materials, as indicated by the 'E4' suffix. It is compatible with standard automated PCB assembly processes and reflow soldering.
What is the load capacitance specification for the SN74S151NSRE4?
The SN74S151NSRE4 has a specified load capacitance (CL) of 15pF, which represents the standard capacitive load used during timing characterization. Operating the output into higher capacitive loads will increase propagation delay beyond the datasheet specifications, so PCB trace lengths and connected load capacitances should be minimized in high-speed applications.
