Product Overview
The SN74AVC16T245 is a Texas Instruments 16-bit noninverting dual-supply bus transceiver in the Signal_Chain category. It provides configurable level shifting with tri-state outputs, supporting bidirectional low-voltage translation among 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic nodes. VCCA and VCCB each operate from 1.2 V to 3.6 V, while the optimized supply range is 1.4 V to 3.6 V.
The A port tracks VCCA and the B port tracks VCCB. The 1DIR, 2DIR, 1OE, and 2OE control inputs are referenced to VCCA. DIR selects A-to-B or B-to-A data transmission for asynchronous bus communication, and an OE high condition places all outputs in tri-state mode.
Package choices include TSSOP-48, TVSOP-48, and 56-pin BGA MICROSTAR JUNIOR. Thermal resistance is specified as 69.9 °C/W for DGG TSSOP, 82.5 °C/W for DGV TVSOP, and 64.6 °C/W for ZQL BGA. The device also includes VCC isolation and Ioff circuitry for powered-down applications.
