HCF4082BEY – TBC

Overview

The STMicroelectronics HCF4082BEY is a dual 4-input AND gate integrated circuit, belonging to the robust 4000 series CMOS logic family. Its primary function is to perform the logical AND operation on two independent sets of four input signals, outputting a high state only when all inputs to a given gate are simultaneously high. A critical design consideration for this part is its relatively slow propagation delay of 85 ns, which necessitates careful timing analysis in high-speed digital systems to avoid race conditions and ensure predictable operation, especially when interfacing with faster logic families.

Key Features

• Dual 4-input AND gate configuration
• Wide operating supply voltage range: 3 V to 20 V
• Low quiescent current: 20 nA
• High noise immunity characteristic of CMOS
• Extended temperature range: -55 °C to +125 °C
• Through-hole PDIP-14 package (20 mm x 7.1 mm x 5.1 mm)
