SN74LVC125APWR – TEXAS INSTRUMENTS

The SN74LVC125APWR is a low-voltage CMOS quad bus buffer with three-state outputs, packaged in a space-saving 14-pin WSON (Wide Small Outline N) package. Operating from a wide voltage range of 1.65V to 5.5V, it offers significant design flexibility across various power supply architectures. Each buffer features a high-impedance, three-state output controlled by an active-low enable pin, allowing for bus sharing and efficient data routing. The device boasts low propagation delays (typically under 6ns at 3V) and low quiescent current (typically under 1µA), making it ideal for low-power applications. Its high output drive capability (up to 12mA) ensures reliable signal transmission even with moderate capacitive loads. The LVC (Low Voltage CMOS) technology ensures compatibility with both 3.3V and 5V systems, simplifying mixed-voltage designs. Common applications include data bus buffering in microcontrollers, memory interface circuits, and peripheral control systems where fast switching speed, low power consumption, and three-state control are critical. The SN74LVC125APWR’s robust performance and compact packaging make it a superior choice for space-constrained, low-power, high-speed digital systems.
