SN74LVC16T245DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC16T245DLR is a dual-supply bus transceiver from the LVC logic family, manufactured by Texas Instruments. It features two independent configurable power rails (VCCA and VCCB) supporting voltage levels from 1.65V to 5.5V. The device provides 16-bit bidirectional data transmission with three-state outputs. Key electrical parameters include a maximum high-level output current of -32mA and a low-level output current of 32mA. Propagation delay is specified at 23.8ns under maximum capacitive load conditions at 2.5V. It operates within a temperature range of -40°C to +85°C and is housed in a 48-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape-and-reel packaging format on official distributor channels. Confirm that the order quantity aligns with standard reel specifications provided by Texas Instruments or authorized partners. Ensure compatibility with surface-mount assembly processes suitable for SSOP-48 components. Cross-reference the manufacturer part number against current datasheets to validate active status and revision history before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust level translation between 1.65V and 5.5V domains. The LVC series offers a balance of speed and power consumption suitable for general-purpose applications. Consider the 48-pin SSOP package constraints regarding PCB real estate and thermal dissipation. Evaluate the propagation delay characteristics against system timing requirements to ensure signal integrity across the 16-bit bus width.
