Frequently Asked Questions
How does the CD4555BNSR decode its 2-bit input into 4 outputs?
The CD4555BNSR takes a 2-bit binary address input and asserts one of 4 active-high output lines corresponding to the binary code — only one output is HIGH at any time — enabling straightforward chip-select demultiplexing for up to 4 peripheral devices from a single 2-bit bus.
What output current does the CD4555BNSR provide and what loads can it drive?
The CD4555BNSR has a maximum output low current (I_OL) of 1.5 mA and is rated for a 50 pF load capacitance, which is typical for 4000-series CMOS logic; it is designed to drive other CMOS inputs rather than high-current loads such as LEDs or relays directly.
In which applications is a 2-to-4 decoder like the CD4555BNSR particularly useful?
The CD4555BNSR is especially useful in memory address decoding for selecting among 4 memory banks, peripheral chip-select generation in microcontroller designs, display segment routing, and simple multiplexed sensor-select circuits where a compact CMOS solution with low quiescent current is preferred.
How does the CD4555BNSR compare to the CD4556 in terms of output polarity?
The CD4555BNSR produces active-high decoded outputs, while the CD4556 produces active-low outputs; choosing between them depends on whether the peripheral chip-select or enable inputs are active-high or active-low, allowing a designer to avoid an external inverter stage.
