Category: Translator

Number of Pins: 14

Short Description

Voltage Translators & Level Shifters 14 pins Tape & Reel (TR) for 1 Voltage Level 14-TSSOP (0.173, 4.40mm Wide) Active 6 Weeks Weeks 1 (Unlimited). There are two independent and programmable power supply rails connected in this 4-bit, non inverting translator (TXB0104). 

 

Using two independently programmable power supply rails, the TXB0104 provides four-bit noninverting translation. A port is designed to track VCCA. It is acceptable for VCCA to accept any supply voltage within the range of 1.2 V and 3.6 V. It is designed to be used in conjunction with the A port when tracking VCCB. There are a wide range of voltages which can be used with the VCCB, ranging from 1.65 V to 5.5 V. By doing this, a low voltage 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5-V voltage node can be converted bidirectionally between any of these voltages in a universal low voltage manner. 

 

There is no way that VCCA can exceed the VCCB. There are no high-impedance outputs on the OE when the OE input is low, so all of the outputs are in high-impedance states. In order for OE to maintain its high-impedance state, it is necessary to connect it to GND via a pulldown resistor when the device is powered up or down. Depending on the power sourcing capacity of the driver, the minimum resistor value will be established.
