Product Overview
Motorola's MC14023UBCP puts three NAND gates in one 14-pin plastic DIP, each gate taking three inputs. A gate's output goes low only when all three of its inputs are high, so one chip can combine three signals into a single active-low line or turn spare gates into inverters.
Key Features
- Function: triple 3-input NAND gate, three independent gates
- Logic family: CMOS, 4000-series 4023 function
- Package: 14-pin plastic DIP, through-hole
- Maker: Motorola
Applications
- Swap out a failed 4023-function NAND on a CMOS control or instrument board
- Combine three enable or status lines into one active-low signal
- Build gate-level logic on a solderless breadboard, where the DIP plugs straight in
Frequently Asked Questions
Can a spare gate work as an inverter?
Yes. Tie all three inputs of the gate together and it inverts. On a gate you are not using at all, tie the inputs to the supply rail rather than leaving them floating, as with any CMOS input.
Which package does the CP in MC14023UBCP stand for?
The 14-pin plastic DIP. In Motorola's UB-series numbering CP is the plastic DIP, CL the ceramic DIP and D the SOIC, so a board laid out for another body takes a different suffix.
In Motorola's CMOS numbering the MC140xx parts carry the 4000-series function in their last digits, so the MC14023 is a 4023 under a batwing logo. Find the 4023 on the schematic and you have found its seat.
