SN74LVCZ245ADWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCZ245ADWR is an octal bus transceiver with three-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 2.7 V to 3.6 V. The device features inputs that accept voltages up to 5.5 V, providing compatibility with 5-V systems. At 3.3 V, the maximum propagation delay is 6.3 ns. It is housed in a 20-SOIC package and supports industrial temperature ranges.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bidirectional data transmission capability
• Input tolerance for 5.5-V signals while operating at lower voltages
• Three-state output design for bus line isolation

Buffers, Drivers, Receivers, Transceivers Applications

• Memory mapping control
• Clock driving and buffering
• Bus-oriented communications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' or 'E4' if environmental compliance or lead-free status is required, as these denote manufacturing variations. Confirm the SOIC-20 package dimensions against your PCB footprint. Ensure the 2.7 V to 3.6 V supply range aligns with your system power rails. Check the datasheet for specific thermal dissipation requirements under high load conditions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between 3.3-V logic and 5-V tolerant peripherals without external level shifters. It is suitable for applications requiring moderate speed with low power consumption. Compare against the standard SN74LVC245A if higher voltage operation (1.65 V) is needed. Consider the SN74LVCC3245A for dual-supply level translation scenarios.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the LVCZ family, which is optimized for 3.3-V operation. It differs from the standard LVC245A by its specific input voltage tolerance characteristics. The Z variant ensures robust performance in mixed-voltage environments common in modern embedded systems and consumer electronics.
