The TC74HC4051AFT(EL) is a high-speed CMOS analog multiplexer/demultiplexer from Toshiba Semiconductor and Storage. This device utilizes silicon gate CMOS technology, delivering low on-resistance and high off-resistance for precise analog and digital signal switching.

Applications

• Analog signal routing and selection
• Data acquisition systems
• Audio and video switching
• Communication equipment
• Test and measurement instruments

Features

• Low on-resistance: RON = 70 Ω (typ.) at VCC = 5 V
• High off-resistance: ROFF = 100 MΩ (min.)
• Wide operating voltage range: VCC = 2 V to 6 V
• Low power dissipation: ICC = 4 μA (max.) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28 % VCC (min.)
• Control input levels: VIL = 0.8 V (max.), VIH = 2.0 V (min.)

Benefits

• Ensures accurate analog signal transmission with minimal distortion due to its low on-resistance.
• Provides excellent channel isolation by minimizing signal leakage in the off state with its high off-resistance.
• Offers versatility in power supply design due to its wide operating voltage range.
• Reduces energy consumption in portable and energy-conscious applications.
• Enhances system reliability in noisy environments due to its high noise immunity.
• Facilitates easy integration with different logic families through its well-defined control input levels.
