The TC74HC153AF is a high-speed CMOS dual 4-input multiplexer fabricated with silicon gate CMOS technology. It contains two independent 4-input multiplexers, each with its own select inputs (A and B) and enable input (E). Each multiplexer selects one of four data inputs (D0-D3) and routes the selected input to the output (Y). The enable input, when high, disables the output.

Applications

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

Features

• High-speed operation: tpd = 15 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
• Separate enable inputs for each multiplexer

Benefits

• High Speed: Enables fast data selection and switching in digital systems.
• Low Power Consumption: Ideal for energy-efficient designs and battery-powered devices.
• High Noise Immunity: Provides reliable operation in noisy environments.
• Wide Operating Voltage: Offers flexibility in power supply selection.
• Dual Multiplexer: Two multiplexers in a single package save board space.
• Separate Enables: Allows for independent control of each multiplexer.

Additional Details

The TC74HC153AF is supplied in a 16-pin package. The select inputs (A and B) determine which of the four data inputs is routed to the output. The enable inputs (E1 and E2), when high, force the corresponding outputs low. The operating temperature range is -40°C to +85°C. This dual multiplexer provides a compact and efficient solution for data selection and routing in various digital applications.
