- True output polarity eliminates the need for external inverters when active-high decoded outputs are required
- CMOS 4000 family compatibility ensures low static power consumption and wide supply voltage range for diverse system designs
- 16-pin TSSOP surface-mount package enables compact PCB layouts for high-density digital logic applications
Applications
The CD4555BPWG4 is used in digital systems for address decoding, memory bank selection, and data demultiplexing, where a 2-bit binary code must select one of four output lines. It is well-suited for microprocessor bus decoding, I/O port expansion, and data routing circuits in embedded systems, industrial controllers, and communication equipment. Its dual-channel architecture allows two independent decode operations simultaneously, reducing IC count and board space in complex digital designs.

Frequently Asked Questions
What is the function of the CD4555BPWG4?
The CD4555BPWG4 is a dual 2-to-4 line binary decoder and demultiplexer. Each of its two independent channels decodes a 2-bit binary input into one of four active-high output lines, enabling address decoding and data routing in digital logic systems.
How many decoder channels does the CD4555BPWG4 have?
The CD4555BPWG4 contains two independent decoder/demultiplexer channels, each with a 2-line input and 4-line true-polarity output, allowing two separate 2-to-4 decoding operations to be performed simultaneously in a single 16-pin package.
What logic family does the CD4555BPWG4 belong to?
The CD4555BPWG4 belongs to the CMOS 4000/14000/40000 logic family, known for its low power consumption, wide supply voltage range, and broad compatibility with other 4000-series CMOS devices used in digital logic systems.
What package does the CD4555BPWG4 use?
The CD4555BPWG4 is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package) surface-mount package, identified by JESD-30 code R-PDSO-G16, providing a compact footprint for automated PCB assembly in space-constrained designs.
What is the output polarity of the CD4555BPWG4?
The CD4555BPWG4 provides true (non-inverted, active-high) output polarity, meaning the selected output goes HIGH when the corresponding binary input code is applied, simplifying interfacing with active-high enable inputs on downstream logic devices.
