SN74LVTH245APWE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH245APWE4 is an octal bus transceiver from the LVTH logic series, manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 2.7 V to 3.6 V. The device utilizes a TSSOP-20 surface-mount package and supports LVTTL input and output levels. Key electrical characteristics include a maximum propagation delay of 2.3 ns at 3.3 V, with low-level and high-level output currents rated at 64 mA and -32 mA respectively. It functions as a non-inverting buffer and driver suitable for bidirectional data bus applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight independent bidirectional channels for efficient data bus management.
• Three-state outputs enable direct connection to bus lines without additional pull-up or pull-down requirements.
• LVTTL-compatible input and output levels ensure seamless integration with standard logic families.

Buffers, Drivers, Receivers, Transceivers Applications

• Bidirectional data bus architectures in embedded systems
• Memory interface circuits requiring level translation between 3.3V domains
• High-speed data transmission lines in industrial control equipment

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates RoHS compliance and lead-free manufacturing status according to Texas Instruments documentation. Confirm the package type matches the required TSSOP-20 footprint for PCB layout compatibility. Ensure the operating temperature range aligns with the intended environmental conditions of the final assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require robust bidirectional data transfer with strong drive capabilities. The LVTH series offers higher current drive compared to standard LVC devices, making it suitable for driving capacitive loads on long buses. Verify that the 3.3V supply voltage matches the system power rails before implementation.
