Product Overview
The Shift Register (Left, Right & Programmable) is a fundamental digital logic IC designed for efficient data manipulation in sequential circuits. Built with high-reliability CMOS technology, this component supports bidirectional shifting (left/right) and programmable configurations, making it adaptable for diverse applications like data storage, transfer, or LED matrix control. Its low-power operation ensures minimal heat dissipation, while the industrial/commercial grade guarantees stability across temperature variations (-40°C to +85°C). The register features cascadable outputs for expanded bit widths and TTL-compatible inputs/outputs for seamless integration with microcontrollers, FPGAs, or other logic families. With a typical propagation delay of <20ns and operating voltages ranging from 2V to 6V, it balances speed and power efficiency. The durable plastic package resists moisture and mechanical stress, ensuring longevity in lab or field environments. Whether used for serial-to-parallel conversion, ring counters, or memory addressing, this shift register delivers precise timing and signal integrity for reliable digital system performance.
FAQs
1. What is the difference between left-shift and right-shift registers?
Left-shift registers move data toward the most significant bit (MSB) with each clock pulse, while right-shift registers shift data toward the least significant bit (LSB). Programmable variants can switch directions based on control signals.
2. Can this shift register interface directly with a 5V Arduino?
Yes, most CMOS-based shift registers are 5V-tolerant and compatible with Arduino’s TTL logic levels. However, verify the specific IC’s datasheet for absolute maximum voltage ratings to avoid damage.
3. Are there alternatives to shift registers for serial data conversion?
Alternatives include serial-in-parallel-out (SIPO) latch ICs like the 74HC595 or microcontroller-based bit-banging. Shift registers excel in hardware-based speed and simplicity for multi-bit operations.
4. How should I store unused shift register ICs to prevent damage?
Store in anti-static bags or conductive foam, away from moisture and direct sunlight. Ideal conditions are <60% humidity and temperatures between 10°C–30°C to prevent oxidation or solderability issues.
5. What’s the typical clock speed limit for this shift register?
Standard CMOS shift registers operate up to 20–50MHz, depending on the variant. High-speed versions (e.g., 74AC series) may reach 100MHz+ but require careful PCB layout to minimize signal noise.
