Descripción

Productos

The 74LVC1G17GW from Nexperia is a single Schmitt trigger buffer in a TSSOP5 (SOT353-1) package. It features a wide supply voltage range of 1.65 V to 5.5 V, overvoltage-tolerant inputs up to 5.5 V, and ±32 mA output drive capability. The Schmitt trigger input provides high noise immunity and converts slowly changing input signals into clean, sharply defined output transitions, making it ideal for signal conditioning in mixed-voltage systems.

Introducción del producto:74LVC1G17GW Presentación del producto

The 74LVC1G17GW is a single Schmitt trigger buffer manufactured by Nexperia in a compact TSSOP5 (SOT353-1) package. The device provides non-inverting buffer action with Schmitt trigger inputs that deliver high noise immunity by converting slowly changing or noisy input signals into clean, well-defined output transitions. The wide supply voltage range of 1.65 V to 5.5 V combined with overvoltage-tolerant inputs (up to 5.5 V) makes it an excellent choice for voltage level translation in mixed 3.3 V and 5 V environments. The IOFF circuitry ensures safe partial power-down operation by disabling the output and preventing backflow current when the device is powered down. With ±32 mA output drive at 3.0 V and propagation delay of typically 5.5 ns, this buffer is suitable for high-speed signal conditioning applications.

Principio de funcionamiento:74LVC1G17GW Principio de funcionamiento

The 74LVC1G17GW operates as a non-inverting buffer with Schmitt trigger input stage consisting of two key subsystems: (1) Schmitt Trigger Input — The input stage incorporates two distinct threshold voltage levels: a higher threshold (VT+) for rising input signals and a lower threshold (VT-) for falling input signals. This hysteresis (VT+ minus VT-) provides noise immunity by ensuring the output does not oscillate or switch erratically when the input signal is near the switching point or has slow edge rates. The input can be driven from either 3.3 V or 5 V sources regardless of the device supply voltage, enabling bidirectional voltage translation. (2) Output Buffer Stage — A CMOS push-pull output stage delivers ±32 mA drive current at 3.0 V supply, capable of directly interfacing with TTL and CMOS logic levels. The IOFF circuit isolates the output when VCC is at ground potential, preventing parasitic current paths in partial power-down scenarios. The device supports unlimited input rise and fall times due to the Schmitt trigger action.
