74ACT16244DGGRG4 – TEXAS INSTRUMENTS

The 74ACT16244DGGRG4 is a high-speed, low-power 8-bit bidirectional transceiver with 3-state outputs, packaged in a 20-pin 4×4 mm QFN (quad flat no-lead) package. It operates from a single 2.0V to 5.5V supply voltage, exhibiting a typical propagation delay of 4.5ns at 3.3V. This device features Schmitt-trigger inputs on both A and B ports, enhancing noise immunity. Each port comprises eight independent transceivers, allowing for flexible data direction control via the DIR pin. The OE (output enable) pin controls the 3-state output, enabling bus sharing capabilities._x000D_

Unlike its predecessors lacking Schmitt-trigger inputs, the 74ACT16244DGGRG4 offers improved signal integrity in noisy environments. Its low power consumption (typical 10mA at 5.5V) is advantageous in battery-powered applications. Common use cases include data bus buffering in embedded systems, interfacing between microcontrollers and peripherals, and high-speed data transmission in industrial control systems. The combination of speed, low power, and noise immunity makes it a superior choice for applications requiring robust and efficient bidirectional data transfer within a constrained power budget. The QFN package facilitates surface-mount assembly, ideal for high-density PCB designs.
