Overview
The TXB0104PWRG4 is a 4-bit bidirectional voltage-level translator from Texas Instruments, housed in a TSSOP-14 package. It utilizes two independent configurable power rails: VCCA (1.2V to 3.6V) and VCCB (1.65V to 5.5V), with the constraint that VCCA must not exceed VCCB. The device supports data rates up to 100 Mb/s and features a propagation delay of 7.4 ns. It operates within an ambient temperature range of -40°C to +85°C and includes an output enable (OE) input circuit powered by VCCA.
Feature Summary
- Supports universal low-voltage bidirectional translation between multiple voltage nodes including 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V.
- Features VCC isolation functionality where all outputs enter a high-impedance state if either VCC input is at ground potential.
- Includes Ioff support to disable outputs during partial power-down modes, preventing destructive current backflow.
Applications
- Audio equipment
- Consumer electronics
- Computer systems and peripherals
Procurement Notes
Verify the G4 suffix indicates RoHS compliance and green material status as per manufacturer specifications. Confirm the TSSOP-14 package dimensions match the target PCB footprint requirements. Ensure the design accommodates the specific VCCA and VCCB voltage rail constraints for proper operation.
Selection Notes
Select this component when interfacing logic families requiring bidirectional level shifting between low-voltage domains (1.2V–3.6V) and higher-voltage domains (1.65V–5.5V). The TSSOP-14 package is suitable for surface-mount assembly. Consider the OE pin configuration for managing high-impedance states during power transitions.
Part Context
This part belongs to the TXB0104 series of voltage-level translators. It shares functional similarities with variants like TXB0104DRG4 and TXB0104RGYRG4 but differs in packaging. The PWRG4 designation specifically identifies the TSSOP-14 form factor with lead-free and halogen-free attributes.
Replacement Considerations
TXB0104PWR is the non-RoHS compliant equivalent. TXB0104DRG4 offers the same electrical performance in an SOIC-14 package. TXB0104RGYRG4 provides identical functionality in a VQFN-14 package.
