SN74LVCH245ADB

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH245ADB is an octal bus transceiver from the Texas Instruments LVCH logic family, designed for bidirectional data transmission with three-state outputs. It operates within a supply voltage range of 2 V to 3.6 V and supports TTL or CMOS input levels while providing LVTTL output levels. The device features a propagation delay of 7 ns and can source or sink up to 24 mA of output current. It is housed in a 20-pin package and functions reliably across an industrial temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm pinout compatibility and package type. Ensure the component meets RoHS standards if required by your assembly process. Confirm moisture sensitivity handling procedures are followed during storage and soldering to prevent damage.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal width is required for bidirectional communication. The LVCH series offers lower power consumption compared to older LVC families. Ensure the system voltage aligns with the 2 V to 3.6 V operating range and that the load capacitance does not exceed specifications for the desired speed.
