Aplicaciones
The SN74LVC1G04DBVR from Texas Instruments is a single inverter gate in a compact SOT-23-5 package, operating from 1.65V to 5.5V. It performs the Boolean function Y = NOT(A) with a maximum propagation delay of 3.3ns at 3.3V and ±24mA output drive. Over-voltage tolerant inputs up to 5.5V and Ioff circuitry enable mixed-voltage designs and live insertion. With 10µA max static current and -40°C to +125°C operation, it is ideal for logic inversion, level translation, and glue logic in space-constrained applications.
The SN74LVC1G04DBVR is a single-stage CMOS inverter gate that performs the Boolean function Y = NOT(A). When the input A is at logic HIGH (near VCC), the PMOS transistor turns off and the NMOS transistor turns on, pulling the output Y to logic LOW (near GND). Conversely, when the input is logic LOW, the PMOS turns on and the NMOS turns off, pulling the output HIGH. The push-pull CMOS output stage provides symmetrical ±24mA drive capability at 3.3V, enabling it to drive moderate capacitive loads directly. The input stage is designed to tolerate voltages up to 5.5V regardless of VCC, allowing the device to be used as a level translator from higher-voltage logic to a lower-voltage domain. The Ioff circuitry ensures that when VCC is 0V, the output enters a high-impedance state, preventing damaging backflow current during partial-power-down or live insertion events. The internal ESD protection clamps on all pins provide robustness against electrostatic discharge events.
