The MC74ACT153DR2 is a commonly used integrated circuit (IC) component that belongs to the 74ACT series, which is part of the broader 7400 series of TTL logic gates. The MC74ACT153DR2 is a dual 4-input multiplexer, meaning it has two independent multiplexers, each with four input channels and two outputs.
Key features of the MC74ACT153DR2 include:
1. Dual 4-Input Multiplexers: The IC integrates two identical multiplexers on a single chip, making it highly space-efficient and cost-effective.
2. 4-Channel Input: Each multiplexer within the IC has four input channels, allowing a wide range of data input options.
3. Select Inputs: The IC features two select inputs, commonly referred to as S0 and S1. These inputs control the selection of either 1 of 4 inputs for each multiplexer.
4. Output Enable: The MC74ACT153DR2 has an active-low output enable input, denoted as OE. When OE is low, the outputs of both multiplexers are enabled. Conversely, when OE is high, the outputs become disabled.
5. Common Select Input: The IC also possesses a common select input, referred to as SEL or SELAB, which allows the user to select one of the multiplexers (in case it is required to operate either independently or collectively)
