CD74HCT42E TI BCD-to-Decimal Decoder | 16-PDIP | 4.5V-5.5V, High-Speed CMOS

Product Overview

The CD74HCT42E is a high-speed CMOS BCD-to-Decimal decoder from Texas Instruments, designed to convert a 4-bit Binary Coded Decimal (BCD) input into one of ten decimal outputs. It is fabricated with silicon gate technology, combining the low power consumption of CMOS with the speed of LSTTL. The device operates over a supply voltage range of 4.5V to 5.5V, making it ideal for 5V logic systems. The CD74HCT42E is offered in a 16-pin PDIP package, suitable for through-hole mounting in industrial and consumer applications.
