SN74LVC8T245DBQR Description

Short technical summary and product information.

The SN74LVC8T245DBQR from Texas Instruments is an 8-bit, dual-supply bus transceiver designed for bidirectional voltage level translation. This device supports a fully configurable dual-rail design, allowing each port to operate independently over the full 1.65-V to 5.5-V power-supply range. This enables universal low-voltage bidirectional translation between common voltage nodes like 1.8-V, 2.5-V, 3.3-V, and 5.5-V.

 

The transceiver features 3-state outputs, controlled by direction-control (DIR) and output-enable (OE) inputs. It is optimized for asynchronous communication between data buses, transmitting data bidirectionally. The device includes features such as VCC isolation, Ioff for partial power-down applications, and robust ESD protection exceeding 4000-V HBM.

 

Packaged in a 24-SSOP (0.154", 3.90mm Width) surface-mount configuration, the SN74LVC8T245DBQR is suitable for various applications including personal electronics, industrial systems, enterprise solutions, and telecommunications. Its operating temperature range is -40°C to 85°C (TA).
