مقدمة المنتج:CD4081BE مقدمة المنتج

The CD4081BE from Texas Instruments contains four independent 2-input AND gates. Each gate implements Y = A AND B; the output is HIGH only when both inputs are HIGH. While AND gates can be constructed from NAND gates plus inverters, the CD4081 provides the AND function directly, saving components and propagation delay. The 3V-18V supply range makes it suitable for everything from 3.3V microcontroller interfaces to 12V automotive logic. The near-zero quiescent current is ideal for battery-powered designs. The CD4081 complements the CD4071 (OR) and CD4011 (NAND) in the CD4000B logic family, giving designers all fundamental 2-input gate functions in compatible packages. The BE suffix denotes the PDIP-14 package with full temperature range.

مبدأ العمل:CD4081BE مبدأ العمل

Each AND gate in the CD4081BE performs Y = A · B. The output is HIGH only when both inputs A and B are HIGH simultaneously. If either or both inputs are LOW, the output is LOW. Truth table: (0,0)→0; (0,1)→0; (1,0)→0; (1,1)→1. The AND function is the logical equivalent of a series switch: both switches must be closed for current to flow. In clock gating: the clock signal AND a gate signal produce a gated clock that only toggles when the gate is HIGH. In enable logic: a peripheral is enabled only when BOTH the chip-select AND the read/write signal are active. The CMOS AND gate is typically implemented as a NAND gate followed by an inverter, both using complementary PMOS/NMOS pairs. The 60ns propagation delay at VDD=10V is adequate for medium-speed applications.

Application Scenarios:In which products and applications isCD4081BE مستعمل

Clock Gating: Clock → input A; gate enable → input B; output = gated clock; clock passes only when enable is HIGH
Chip Select AND RW: Chip select → input A; Read signal → input B; output = active read strobe for this chip
Both-Active Enable: Switch 1 AND Switch 2 must both be ON → output HIGH; either OFF → output LOW
3-Input AND: Cascade: gate 1 output (A AND B) → gate 2 input; C on gate 2 other input; output = A AND B AND C

CD4081 is the CMOS 4000-series quad 2-input and gate operating over the wide 3-18V supply range. The HEF4081 (NXP) and MC144081 (onsemi) are direct pin-compatible equivalents. For higher speed at the cost of narrower voltage range, the 74HC08 HC/HCT families offer significantly faster propagation delay and lower power consumption at 2-6V. Surface-mount versions use the BM/M suffix (SOIC); through-hole versions use the BE suffix (DIP).
