Introducción del producto:MC14011BDG Presentación del producto

The MC14011BDG from onsemi is a quad 2-input NAND gate, part of the MC14000B CMOS logic family. It contains four independent 2-input NAND gates in a single 14-pin SOIC package. The NAND function is functionally complete — any Boolean logic function can be implemented using only NAND gates, making the MC14011B one of the most versatile logic ICs available. The wide 3V to 18V supply range suits both 5V logic systems and industrial 12V/15V applications. The buffered B-series outputs provide rail-to-rail output swing with ±3.4mA drive at 10V. The >50% noise immunity and low quiescent current (20µA max at 20V) make it reliable in noisy industrial environments. The device is pin-compatible with the CD4011B from TI and HEF4011B from Nexperia.

Principio de funcionamiento:MC14011BDG Principio de funcionamiento

Each of the four NAND gates uses a standard CMOS implementation of the 2-input NAND function. The output Y is low only when both inputs A and B are high; for all other input combinations, Y is high. The CMOS implementation uses a series PMOS pull-up network and a parallel NMOS pull-down network. The B-series buffered output adds two additional inverter stages after the basic NAND gate, providing higher gain, faster edge rates, and more symmetrical output drive characteristics compared to the unbuffered A-series. The buffered output also provides better noise immunity because the sharper transfer characteristic means the output transitions more decisively. The wide supply range (3-18V) is achieved through the use of standard metal-gate CMOS technology, which has inherently wider operating voltage than modern silicon-gate processes.

Application Scenarios:In which products and applications isMC14011BDG usado

Set-Reset Latch: Cross-couple two NAND gates to create an SR latch. Gate 1 output feeds Gate 2 input and vice versa. The SET input (active low) forces Q high; the RESET input (active low) forces Q low. When both are high, the latch holds its state. This is the most fundamental memory element in digital logic. The remaining two gates can implement additional logic.
Industrial Interlock Logic: Implement safety interlocks in a 12V industrial control system. Use NAND gates to combine multiple safety conditions (door closed, guard present, pressure OK). The NAND gate outputs a low (activating a safety relay) only when all conditions are satisfied. The 12V supply operation and >50% noise immunity ensure reliable operation in the industrial environment.
Logic Gate Composing: Since NAND is functionally complete, implement any logic function using only MC14011B devices. An inverter is a NAND with tied inputs; an AND is a NAND followed by an inverter; an OR is implemented using DeMorgan’s theorem. This makes the MC14011B an excellent stocking choice — one device type can implement any combinational logic function.
