ON Semiconductor MC74LCX157DTR2 Quad 2-Input Multiplexer

The MC74LCX157DTR2 is a high-performance, quad 2-input multiplexer designed by ON Semiconductor, a leading innovator in energy-efficient electronics. This device is part of the LCX family, which is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining CMOS low power dissipation.

This multiplexer is capable of selecting one of two inputs for each output based on the select inputs. It features four identical 2-input multiplexers with 3-state outputs that can be used to move data from two groups of registers to four common output buses. The 3-state outputs can be used to interface with bus-organized systems and are capable of driving heavily loaded outputs with up to 24mA of drive current.

Key features of the MC74LCX157DTR2 include:

• 5V tolerant inputs and outputs for interfacing with 5V logic levels
• High-speed operation: t_PD 5.3ns (max) at 3.3V
• Low power dissipation: I_CC 4µA (max) at TA = 25°C
• Power-down high impedance inputs and outputs
• Supports live insertion and withdrawal (partial power-down)
• ±24mA output drive at 3.3V
• Implements patented noise/EMI reduction circuitry
• Latch-up performance exceeds 500mA
• ESD performance:
  • Human-body model: >2000V
  • Machine model: >200V

The device is designed for low-voltage operation (2.3V to 3.6V), making it ideal for interfacing with high-speed microprocessors. It also provides the capability to work in mixed 3.3V and 5V environments, which is common in legacy system upgrades. Its fast propagation delay and low power consumption make it suitable for a wide range of applications in telecommunications, computing, and industrial markets.

ON Semiconductor's MC74LCX157DTR2 comes in a TSSOP-16 package, ensuring a compact footprint for space-constrained applications. It is also specified for a wide operating temperature range from -40°C to +85°C, providing reliable performance across diverse environmental conditions.

Overall, the MC74LCX157DTR2 multiplexer from ON Semiconductor offers a versatile and efficient solution for data routing applications requiring high-speed, low-power operation, and 5V tolerant interfaces.
