HCC4035B / HCF4035B CMOS Shift Register

Overview

The HCC4035B (extended temperature range) and HCF4035B (intermediate temperature range) are monolithic integrated circuits fabricated in Metal Oxide Semiconductor technology. These devices belong to the "B" series of CMOS logic devices, offering a versatile 4-bit static shift register with synchronous parallel or serial entry. Designed for high noise immunity and low power consumption, these components are suitable for a wide range of digital applications requiring serial-to-parallel or parallel-to-serial data conversion.

The 4035B series features three-state outputs, allowing for bus-oriented applications. The devices operate across a wide voltage range (3V to 18V), making them compatible with various logic families. The extended temperature range of the HCC4035B (-55°C to +125°C) makes it particularly suitable for military and industrial applications, while the HCF4035B (operating from -40°C to +85°C) serves well in commercial applications.
