Description

Product Overview

The SN74LVC1G17DSFR is a single Schmitt-trigger buffer from Texas Instruments, packaged in a 6-pin NanoStar(TM) WFBGA (DSF) package. It is designed for 1.65V to 5.5V VCC operation and provides signal conditioning with hysteresis, making it ideal for noisy input environments. The device features overvoltage tolerant inputs and partial power-down isolation.

Key Specifications

Features

  • Schmitt-trigger input provides hysteresis for noise immunity
  • Wide VCC operating range: 1.65V to 5.5V
  • Overvoltage tolerant inputs up to 6.5V
  • Ioff support for partial power-down mode
  • Ultra-compact 1.0 × 1.0 mm NanoStar BGA package
  • Low power consumption

Applications

  • Signal conditioning for noisy environments
  • Level translation and interface buffering
  • Clock and data signal restoration
  • Portable battery-powered devices
  • Industrial control input conditioning

The SN74LVC1G17 is a single Schmitt-trigger buffer from Texas Instruments’ LVC logic family. It is optimized for 1.65V to 5.5V operation and features Schmitt-trigger inputs that provide hysteresis for superior noise rejection on slowly changing or noisy input signals. The device is particularly useful for converting slowly changing analog signals into clean digital outputs. The DSF package variant uses the ultra-compact NanoStar WFBGA footprint, making it ideal for space-constrained applications where PCB area is at a premium.

The SN74LVC1G17 employs a Schmitt-trigger input stage that features two distinct threshold voltages: a higher threshold (VT+) for rising inputs and a lower threshold (VT-) for falling inputs. The voltage difference between these thresholds constitutes the hysteresis, which prevents output oscillation when the input signal is near the switching threshold or contains noise. The push-pull output stage provides active drive in both high and low states, ensuring fast edge rates. The Ioff circuitry disables the output when VCC is at 0V, allowing the device to be used in systems with partial power-down without back-driving the supply rail.
