SN74LVCH16T245DGGR

The SN74LVCH16T245DGGR is a 16-bit dual-supply bus transceiver manufactured by Texas Instruments. This device is designed for configurable voltage translation, allowing mixed-voltage-mode data communications. It operates with two separate configurable power-supply rails, with both the A and B ports accepting supply voltages from 1.65 V to 5.5 V.

Key electrical specifications include a maximum data rate of 200 Mbps and a propagation delay of 6.4 ns. The transceiver features 3-state outputs, bus-hold on data inputs, and overvoltage-tolerant inputs and outputs. It also supports partial power-down mode (Ioff).

This component is available in a 48-TSSOP package and is designed for surface mount applications. The operating temperature range is -40°C to 85°C. Latch-up performance exceeds 100 mA per JESD 78, Class II, and ESD protection exceeds JESD 22.

Features such as VCC isolation, where all outputs are in a high-impedance state if either VCC input is at GND, enhance its usability in various system designs. The bus-hold feature eliminates the need for external pull-up and pull-down resistors.
