The SN74AS157D is a popular IC (Integrated Circuit) component that belongs to the 74AS series developed by Texas Instruments. It is a quadruple 2-input multiplexer, designed to combine four separate data inputs onto a common output based on the select inputs.
Here are some key features and an overview of the SN74AS157D:
1. Input and Output Configuration:
The SN74AS157D consists of four independent 2-input multiplexers, each having two data inputs (Y0, Y1) and a single common output (Z). The input select lines (S0 and S1) control which data input is transferred to the output. Additionally, the input pins (A and B) are used to select a particular multiplexer.
2. Logic Compatibility:
It follows the Advanced Schottky (AS) logic family, which provides a balance between speed and power consumption. The AS logic ensures higher operating speeds compared to standard TTL (Transistor-Transistor Logic) ICs.
3. Wide Operating Voltage Range:
The IC operates within a wide voltage range of 4.5V to 5.5V, making it compatible with various power supply configurations.
4. Low Power Consumption:
The SN74AS157D has a low power dissipation characteristic, making it suitable for low-power applications. This feature helps conserve energy and enhance battery life in portable devices
