Overview
The SN74LVC257ABQBR is a quadruple 2-line to 1-line data selector manufactured by Texas Instruments. It operates from a supply voltage range of 1.65V to 3.6V and features inputs that accept voltages up to 5.5V. The device achieves a maximum propagation delay (tpd) of 4.6ns at 3.3V, with typical output ground bounce (VOLP) less than 0.8V at VCC = 3.3V and TA = 25°C. It is housed in a 16-WQFN package.
Feature Summary
- Operates within a low voltage range of 1.65V to 3.6V
- Input tolerance allows acceptance of voltages up to 5.5V
- High-speed performance with maximum tpd of 4.6ns at 3.3V
- Low output ground bounce typically below 0.8V
Applications
- Data routing in portable electronic devices
- Signal selection in battery-powered systems
- Interface bridging between 5V and lower voltage logic domains
Procurement Notes
Verify the specific suffix 'ABQBR' corresponds to the 16-WQFN package variant when ordering. Confirm that the 5.5V input tolerance requirement aligns with your system's signal levels. Ensure the operating voltage stays within the 1.65V to 3.6V range for optimal performance. Check for RoHS compliance documentation if required by your manufacturing standards.
Selection Notes
Select this component when low power consumption and high speed are critical for 1.8V or 3.3V systems. The 5.5V tolerant inputs make it suitable for interfacing with legacy 5V logic without level shifters. Consider the WQFN package size constraints during PCB layout. Compare against standard LVC variants if higher drive strength or different packaging is needed.
Part Context
This part belongs to the SN74LVC257A family of quadruple 2-to-1 multiplexers. It shares functional compatibility with other LVC series devices but offers specific electrical characteristics optimized for low-voltage operation. The ABQBR designation indicates the specific tape-and-reel packaging and temperature grade provided by Texas Instruments.
Replacement Considerations
SN74LVC257APWRG4 is a pin-compatible alternative in a TSSOP package. SN74HC257DR offers similar functionality but operates at higher voltages (2V to 6V) with slower speeds. Verify package dimensions and electrical specifications before substitution.
