LSF0204 Voltage Level Translator

Texas Instruments' LSF family are bidirectional voltage level translators that operate from 1.0 V to 4.5 V (Vref_A) and 1.8 V to 5.5 V (Vref_B). This allows bidirectional voltage translations between 1.0 V and 5.0 V without the need for a direction terminal in open-drain or push-pull applications. LSF family supports level translation applications with transmission speeds greater than 100 MHz for open-drain systems utilizing a 15 pF capacitance and 165 Ω pull-up resistor.

Features
  • Provides bidirectional voltage translation with no direction terminal
  • Less than 1.5 ns max propagation delay
  • Supports high speed translation, greater than 100 MHz
  • Supports Ioff, partial power down mode
  • Low standby current
  • 5 V tolerance I/O port to support TTL
  • Allows bidirectional voltage level translation between:
    • 1.0 V ↔ 1.8/2.5/3.3/5 V
    • 1.2 V ↔ 1.8/2.5/3.3/5 V
    • 1.8 V ↔ 2.5/3.3/5 V
    • 2.5 V ↔ 3.3/5 V
    • 3.3 V ↔ 5 V
