ON Semiconductor MC74LVX157DTR2G Multiplexer

The ON Semiconductor MC74LVX157DTR2G is a high-performance, low-voltage quad 2-input multiplexer from ON Semiconductor's advanced CMOS logic family. This device is designed to operate with a power supply range of 2.0V to 3.6V, making it suitable for battery-operated systems and portable electronic devices. Its low-power consumption combined with high-speed operation and the ability to drive 10 LSTTL loads make this multiplexer an excellent choice for a wide array of data selection and control applications.

The MC74LVX157DTR2G features four individually selectable 2-input multiplexers with common select inputs and an output enable input. Each multiplexer has two data inputs (A0, A1, B0, B1, C0, C1, D0, D1), one output (Y0, Y1, Y2, Y3), a common select input (S), and an output enable (OE) input. The select input determines which of the data inputs is connected to the corresponding output. When the output enable (OE) input is low, the selected data input is passed through to the output. If OE is high, the outputs are in a high-impedance state, effectively disconnecting the outputs from the circuit.

Key features of the MC74LVX157DTR2G include:

• High-speed operation: t_PD 4.2 ns (max) at V_CC = 3.3V
• Low power dissipation: I_CC = 2 μA (max) at T_A = 25°C
• Power-down high-impedance inputs and outputs
• Supports live insertion and withdrawal (partial power-down mode)
• Multiple package options: Available in TSSOP-16 packaging
• Lead-free and RoHS compliant

This device is characterized for operation from -55°C to +125°C, ensuring reliability across a broad range of temperature conditions. It is also designed with over-voltage tolerant inputs and outputs up to 3.6V, which helps in interfacing with higher voltage logic levels without additional level shifting hardware.

The MC74LVX157DTR2G multiplexer is ideal for applications requiring the routing of signals from multiple sources to a single destination, such as data multiplexing, signal gating, and function generation. Its compact form factor and high level of integration make it a smart choice for designers looking to reduce board space and improve system performance in their digital logic circuits.

ON Semiconductor's commitment to quality ensures that the MC74LVX157DTR2G multiplexer meets the stringent requirements of the electronics industry, providing a reliable and efficient solution for complex digital systems.
