74HC298 Description

The 74HC298 is a high-speed CMOS (Complementary Metal-Oxide-Semiconductor) device made by Hitachi, which is commonly used as an 8-bit shift register with a parallel load capability. It features three asynchronous reset inputs (SR, SP, and SD), an 8-bit output register, and a serial input. The 74HC298 can be cascaded to create larger shift registers when needed. It operates on a power supply voltage range of 2V
This circuit is controlled by the signals word select and clock. When the word select input is taken low word 1 (A 1, B1, C1 and D 1) is presented to the inputs of the flip-flops, and when word select is high word 2 (A 2, B 2, C2 and D2) is presented.
