Register

A register

Types

By data movement

Specialized types

A

• FIFO Register – First-In-First-Out buffer

• Accumulator – Register that stores ALU results

• Status Register – Holds flags (carry, zero, etc.)

• Index Register – Used for addressing modes in CPUs

• Control Register – Holds configuration bits in microcontrollers

ICs

Common ICs used as a registers are:

• 74HC174 – Hex D flip-flop with clear (PIPO)

• 74HC164 – 8-bit SIPO shift register

• 74HC165 – 8-bit PISO shift register

• 74HC194 – 4-bit bidirectional universal shift register

• 74HC373 – 8-bit transparent latch (level-sensitive)

• 74HC574 – 8-bit edge-triggered register (PIPO)
