SN75C1167NSRG4 – TEXAS INSTRUMENTS

The SN75C1167NSRG4 is a Texas Instruments single-channel, bidirectional, voltage-level translator with open-drain outputs. Specifically designed for interfacing between 3.3V and 5V logic levels, it operates over a wide input voltage range of 2.0V to 5.5V, ensuring compatibility across various systems. The device features a robust ESD protection exceeding 2kV (HBM), crucial for noisy environments. Its open-drain configuration allows for flexible pull-up resistor selection, optimizing current consumption and noise immunity depending on the application. The output current is specified at 10mA (min)._x000D_

Packaged in a space-saving 4-pin SOT-23 (SC-70-6) surface mount package, the SN75C1167NSRG4 simplifies PCB layout. Common applications include interfacing microcontrollers operating at 3.3V with peripherals running at 5V, such as sensors, actuators, or memory devices. Its low propagation delay (<15ns) ensures minimal latency in data transfer. The advantage of this device lies in its compact size, robust protection, and the flexibility offered by its open-drain output, making it an ideal choice where space is limited, and reliable signal translation between differing logic voltages is paramount. Its simple single-supply operation further simplifies circuit design.
