SN74LVCH16543ADGG

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH16543ADGG is a 16-bit registered transceiver from the LVCH logic family, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and features three-state outputs. The device utilizes a TSSOP-48 package and supports surface-mount installation. Key electrical parameters include a propagation delay of 4.9 ns at 2.7 V and 4.2 ns at 3.3 V, with a maximum static current of 20 uA. Output drive capabilities are specified as 32 mA for low-level output and -24 mA for high-level output. The component functions as a non-inverting latched transceiver suitable for bus-oriented applications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DGGR' or 'DGG' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the order matches the required operating temperature range and logic family characteristics. Cross-reference the component marking with the official identification guide to prevent counterfeit substitution.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit data transfer with built-in registration. The LVCH series offers performance comparable to LVC but with optimized switching characteristics. Consider the TSSOP-48 package constraints for PCB layout and thermal management during the design phase.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCH16543 family of 16-bit registered transceivers. It is designed for high-speed data transmission in low-voltage environments.
