SN74LVCH16T245DGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH16T245DGVR is a 16-bit dual-supply bus transceiver from Texas Instruments, designed for voltage level translation between two independent power domains. It features configurable voltage conversion capabilities with a supply voltage range of 1.65V to 5.5V. The device provides three-state outputs and supports bidirectional data flow controlled by a direction pin. Key electrical characteristics include a propagation delay of 6ns at 3.3V with 50pF load, output drive currents of 32mA, and an operating temperature range of -40°C to +85°C. It is housed in a 48-pin TVSOP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DGVR' to confirm the TVSOP-48 package and tape-and-reel packaging format. Ensure compatibility with the target board's thermal requirements for surface-mount installation. Cross-reference the manufacturer datasheet for exact pinout definitions and recommended soldering profiles to guarantee reliable assembly and long-term performance.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 16-bit wide buses between systems with differing supply voltages within the 1.65V to 5.5V range. Consider the 6ns propagation delay for timing-critical applications. Evaluate the need for power-down isolation to prevent back-powering during standby modes. Compare against standard non-translating transceivers if voltage levels are identical across the system.
