Key Features
- 4-to-16 line decoding with integrated address latches eliminates external latch ICs in microcontroller address bus expansion designs
- Active-high outputs with 50 pF load drive capability support direct LED segment and relay driver interfacing without buffer stages
- Wide 3V to 18V CMOS supply range from the 4000 family ensures compatibility with both 5V TTL-adjacent and 3.3V microcontroller systems
Applications
The CD4514BM is used in address decoding and multiplexing applications where a 4-bit binary input must select one of 16 output lines with integral latch hold capability. It is commonly found in legacy industrial control panels, segment display decoders, and keyboard matrix scanning circuits driven by microcontrollers. The CMOS 4000-series architecture makes it suitable for low-power battery-operated systems operating at supply voltages from 3V to 18V.

Frequently Asked Questions
How does the address latch feature of CD4514BM simplify bus-driven decoder designs in a microcontroller system?
The CD4514BM includes a built-in 4-bit address latch that holds the selected output line even after the address bus transitions to a new value. This eliminates the need for an external 74HC75 or similar latch IC in designs where the address bus is multiplexed or time-shared, reducing component count by at least 1 IC and simplifying PCB routing in compact 16-output demultiplexer configurations.
What load capacitance can CD4514BM drive on each output and what does this mean for driving LED segments?
Each output of the CD4514BM is specified for 50 pF load capacitance, with a maximum output low current (Iol) of 1.5 mA at rated supply voltage. For driving LED segments, a current-limiting resistor must be used to keep forward current within the 1.5 mA limit, typically resulting in low-brightness operation. For higher brightness LEDs requiring 10 mA to 20 mA, a transistor or dedicated LED driver such as ULN2003 should buffer the CD4514BM output.
What supply voltage range does CD4514BM support and is it compatible with 3.3V microcontroller GPIO outputs?
The CD4514BM is a CMOS 4000-series device supporting supply voltages from 3V to 18V, which includes 3.3V and 5V operation. At a 3.3V supply, the input high-voltage threshold is approximately 2.3V, meaning standard 3.3V microcontroller GPIO outputs with typical high-level output of 2.7V to 3.3V are fully compatible. However, at 5V supply the input threshold rises to about 3.5V, making 3.3V GPIO signals potentially marginal without a level translator.
How does CD4514BM differ from CD4515BM in terms of output polarity for display control applications?
The CD4514BM has active-high outputs, meaning the selected output goes high while all others remain low. The CD4515BM is the complementary device with active-low outputs where the selected line goes low while others stay high. For common-anode LED display multiplexing where the selected segment is driven by a low signal, CD4515BM is the direct choice, while CD4514BM suits common-cathode displays or relay driver configurations needing a positive-going select pulse.
