The TC74HC151AF is a high-speed CMOS 8-input multiplexer fabricated with silicon gate CMOS technology. It selects one of eight data inputs (D0-D7) based on the three address inputs (A, B, and C) and routes the selected input to the output (Y). An enable input (E) is provided to disable the output when high. A complementary output (W) is also available.

Applications

• Data selection
• Logic function generation
• Parallel-to-serial conversion
• Address multiplexing
• Instrumentation and control systems

Features

• High-speed operation: tpd = 16 ns (typ.) at VCC = 5V
• Low power dissipation: ICC = 4 μA (max) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28 % VCC (min)
• Output drive capability: 10 LSTTL loads
• Symmetrical output impedance: |IOH| = IOL = 4 mA (min)
• Balanced propagation delays: tPLH ≈ tPHL
• Wide operating voltage range: VCC = 2 to 6 V
• Enable input for output control
• Complementary output available

Benefits

• High Speed: Enables fast data selection and switching.
• Low Power Consumption: Suitable for battery-powered and energy-conscious applications.
• High Noise Immunity: Provides reliable operation in noisy industrial environments.
• Wide Operating Voltage: Offers design flexibility in power supply selection.
• 8-to-1 Multiplexing: Allows selection from eight different data sources.
• Enable Input: Provides output control and simplifies system design.
• Complementary Output: Offers added design flexibility.

Additional Details

The TC74HC151AF is supplied in a 16-pin package. The selected input is routed to the Y output when the enable input (E) is low. When E is high, the Y output is low, and the W output is high. This multiplexer is valuable in a variety of applications where multiple data sources need to be selected and routed to a single output. Its operating temperature range is -40°C to +85°C.
