Productos<\/h2>\n

The SN74LVC2G241DCUR is a dual non-inverting buffer and line driver with 3-state outputs, manufactured by Texas Instruments as part of the LVC (Low-Voltage CMOS) logic family. Designed for 1.65-V to 5.5-V VCC operation, this device is organized as two independent 1-bit line drivers with separate output-enable (1OE, 2OE) control inputs, making it ideal for bus-oriented applications requiring selective signal routing. The DCU package (VSSOP-8) occupies only 2.0 x 3.1 mm of board space, enabling high-density PCB layouts. Key highlights include a maximum propagation delay of 4.1 ns at 3.3 V, \u00b124-mA balanced output drive at 3.3 V, over-voltage tolerant inputs up to 5.5 V, and Ioff circuitry that supports live insertion and partial-power-down operation. The device can also serve as a down-translator, converting input logic levels up to 5.5 V down to the VCC rail voltage.<\/p>\n

Designed for operation from 1.65 V to 5.5 V, this device is specifically engineered to improve the performance and density of 3-state memory-address drivers, clock drivers, and bus-oriented receivers and transmitters. The device is organized as two independent 1-bit line drivers, each with its own output-enable control: the 1OE input is active-low and the 2OE input is active-high. When the output-enable condition is met, data passes from the A input to the Y output; when disabled, the output enters the high-impedance (3-state) state, allowing safe bus sharing among multiple devices. A key advantage of this device is its over-voltage tolerant input structure, which accepts signals up to 5.5 V regardless of the VCC supply level. This enables the SN74LVC2G241DCUR to function as a down-translator, converting higher-voltage logic levels to the VCC rail voltage \u2014 a valuable feature in mixed-voltage systems where a 3.3 V or 5 V bus must interface with a lower-voltage controller. The integrated Ioff circuitry ensures that outputs are disabled during power-up or power-down, preventing damaging backflow current and supporting live insertion and partial-power-down applications. Packaged in a compact VSSOP-8 (DCU) footprint of only 2.0 x 3.1 mm, the device minimizes board area while delivering robust \u00b124-mA output drive at 3.3 V and a propagation delay of just 4.1 ns.","working_principle":"The SN74LVC2G241DCUR operates through three functional subsystems:\n\n1. Non-Inverting Buffer Core: Each of the two channels contains a CMOS non-inverting buffer stage. When the corresponding output-enable pin is in the active state (1OE = low for Channel 1; 2OE = high for Channel 2), the buffer passes the logic level at the A input directly to the Y output without inversion. The CMOS push-pull output stage provides symmetric source (IOH) and sink (IOL) current capability \u2014 up to \u00b124 mA at 3.3 V \u2014 ensuring strong signal drive even across long PCB traces or multiple loads. The balanced output architecture minimizes duty-cycle distortion in clock distribution applications.\n\n2. 3-State Output Enable Control: Each channel features an independent output-enable input. When the enable condition is not met (1OE = high or 2OE = low), the output transistors are both turned off, placing the Y output in a high-impedance (Hi-Z) state. This allows multiple devices to share a common bus without contention. During power-up or power-down transients, the Ioff circuitry ensures the outputs remain in Hi-Z, preventing back-drive current from flowing through the device and protecting downstream components. Designers should tie 1OE to VCC via a pull-up resistor and 2OE to GND via a pull-down resistor to guarantee the Hi-Z state during supply transitions.\n\n3. Over-Voltage Tolerant Input and Down-Translation: The input stage is designed to accept voltages up to 5.5 V independently of the VCC supply. When VCC is set to a lower voltage (e.g., 1.8 V or 2.5 V) while the input signal originates from a higher-voltage domain (e.g., 3.3 V or 5 V), the device clamps and level-shifts the input to the VCC logic level at the output. This down-translation capability eliminates the need for external level-shifter ICs in mixed-voltage system designs. The input clamp diodes also provide a defined path for negative undershoots up to -50 mA (IIK), protecting the thin-oxide CMOS gates from damage.","pin_description":"\n
