ON Semiconductor MC74HCT125ADTR2G: Quad Level Shifter

The ON Semiconductor MC74HCT125ADTR2G is a high-performance, quad-level shifter integrated circuit designed for digital signal processing and bus-driving applications. This device features four independent non-inverting buffer/line drivers with 3-state outputs, making it an ideal choice for interfacing between different logic levels in mixed 5V and 3.3V systems.

Constructed using silicon gate CMOS technology, the MC74HCT125ADTR2G offers the high noise immunity and low power consumption characteristic of CMOS integrated circuits, along with speeds comparable to LSTTL. Each buffer has its own output enable pin, which allows for greater flexibility in control and bus management.

Key Features:

• Logic Level Translation: Capable of translating signals from 5V to 3.3V logic levels, making it suitable for interfacing TTL or CMOS logic levels in mixed voltage environments.
• High Output Current: The device can source or sink up to 4 mA at 5V, providing sufficient drive capability for most applications.
• 3-State Outputs: The inclusion of 3-state outputs enables the buffers to be connected directly to a bus while maintaining high impedance when not in use, preventing bus contention.
• Independent Channel Control: Each of the four buffers operates independently, with its own output enable (OE) control, allowing for selective operation of each channel.
• Low Power Consumption: With its CMOS construction, the MC74HCT125ADTR2G maintains low quiescent current, even when operating at high frequencies, making it suitable for power-sensitive applications.
• Wide Operating Temperature Range: The device is designed to operate over a broad temperature range of -55°C to 125°C, ensuring reliability across various environmental conditions.

The MC74HCT125ADTR2G is available in a TSSOP-14 package, providing a compact footprint for space-constrained applications. It is also fully compatible with industry-standard HCT logic products, allowing for easy integration into existing designs without the need for extensive rework.

Whether you're designing a new system that requires logic level translation or upgrading an existing design, the ON Semiconductor MC74HCT125ADTR2G offers a reliable, efficient solution for your digital interfacing needs.
