LSF0204x 4-Bits Bidirectional Multi-Voltage Level Translator for Open-Drain and Push- Pull Application LSF0204, LSF0204D SLVSCP5F –JULY 2014–REVISED JANUARY 2019 level translation applications the need for a direction terminal 3 Description The LSF family consists of bidirectional voltage level translators that operate from 0.8 V to 4.5 V (Vref_A) and 1.8 V to 5.5 V (Vref_B). This range allows for bidirectional voltage translations between 0.8 V and 5.0 V without in open-drain or push-pull applications. The LSF family supports with transmission speeds greater than 100 MHz for open- drain systems that utilize a 15-pF capacitance and 165-Ω pull-up resistor. When the An or Bn port is LOW, the switch is in the ON-state and a low resistance connection exists between the An and Bn ports. The low Ron of the switch allows connections to be made with minimal propagation delay and signal distortion. The voltage on the A or B side will be limited to Vref_A and can be pulled up to any level between Vref_A and 5 V. This functionality allows a seamless translation between higher and lower voltages selected by the user without the need for directional control.

www.ti.com LSF0204, LSF0204D SLVSCP5F –JULY 2014–REVISED JANUARY 2019 Changes from Original (November 2014) to Revision A Page • Changed From a first page Product Preview To a full datasheet ......................................................................................... 1 • Changed text in the Description From: "transmission speeds greater than 100 Mbps" To: "transmission speeds greater than 100 MHz" .......................................................................................................................................................... 1 5 Description (continued) The supply voltage (Vpu#) for each channel may be individually set up with a pull up resistor. For example, CH1 may be used in up-translation mode (1.2 V ↔ 3.3 V) and CH2 in down-translation mode (2.5 V ↔ 1.8 V). When EN is HIGH, the translator switch is on, and the An I/O is connected to the Bn I/O, respectively, allowing bidirectional data flow between ports. When EN is LOW, the translator switch is off, and a high-impedance state exists between ports. The EN input circuit is designed to be supplied by Vref_A. EN must be LOW to ensure the high-impedance state during power-up or power-down.
