Package and integration story
The CD4082BPW comes in a 14-TSSOP (4.40mm width) surface-mount package, a compact footprint for dense PCB layouts where board real estate is constrained. The 0.65mm pin pitch demands careful solder-paste stencil design to avoid bridging between adjacent pins during reflow. This dual 4-input AND gate belongs to the 4000B series, a mature CMOS logic family known for wide supply tolerance and low power consumption. The two independent gates share common power and ground, each with four inputs — useful for gating multiple control signals or implementing combinatorial logic in a single package.
Supply voltage and temperature grade
Operating from 3V to 18V, the CD4082BPW bridges logic domains between 3.3V and 15V systems without a level translator. The wide range makes it suitable for industrial control panels where unregulated rails or battery voltage swings are common. Rated for -55°C to 125°C ambient, this is the military temperature grade. The part functions reliably in engine-bay electronics, outdoor telecom cabinets, or downhole instrumentation where commercial-grade logic would fail. The 1µA max quiescent current means it adds negligible drain in always-powered sensor nodes.
Switching performance and output drive
Maximum propagation delay is 90ns at 15V supply with a 50pF load. At lower supply voltages the delay increases — budget 200-250ns at 5V for timing closure in slower control paths. The 3.4mA source/sink output current drives one or two standard CMOS loads directly; for higher fan-out or longer traces, buffer the output. Input logic levels scale with supply: low threshold is 1.5V to 4V, high is 3.5V to 11V across the 3-18V range. This means a 3.3V microcontroller output may not reliably drive the gate at full 18V supply — check the input high threshold against your logic source at the operating VDD.
Lifecycle and sourcing reality
Sourced to order against BOM quantities through independent distribution; availability and current pricing confirmed at RFQ time. No pin-compatible second-source or successor is listed — this is a single-source position on the BOM. For volume production, consider qualifying an alternate package variant if the 14-TSSOP footprint is not locked.
