74LVC16T245DGVRG4

Overview

The SN74LVC16T245DGVRG4 is a 16-bit dual-supply bus transceiver with configurable voltage translation and tri-state outputs. It operates within a supply voltage range of 1.65 V to 3.6 V for the A port and 2.7 V to 3.6 V for the B port, enabling seamless interface between different logic families. The device features a data rate of up to 500 Mb/s and a propagation delay of 6 ns at 3.3 V. Packaged in a 48-pin TSSOP (DGVR) housing, it supports surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Configurable voltage translation allows flexible interfacing between diverse logic families without external level-shifting components.
• Dual-supply architecture enables independent power domains for input/output ports, supporting mixed-voltage system designs.
• Tri-state outputs provide high-impedance states to prevent bus contention during multi-master communication scenarios.

Applications

• Mobile applications requiring low-power voltage level translation
• Consumer electronics with mixed-voltage logic interfaces
• Industrial control systems utilizing bidirectional data buses

Procurement Notes

Verify the specific suffix 'RG4' indicates RoHS compliance and green manufacturing status as per Texas Instruments standards. Confirm the package type corresponds to the 48-pin Thin Shrink Small Outline Package (TSSOP) variant. Ensure compatibility with the intended voltage levels on both Port A and Port B before integration into the design.

Selection Notes

Select this component when designing systems that require bidirectional data transfer between circuits operating at different voltage levels. The LVC series offers improved performance over standard LVC devices while maintaining low power consumption. Consider the 48-pin TSSOP package constraints regarding PCB space and thermal management requirements for dense layouts.

Part Context

This part belongs to the SN74LVC16T245 family of 16-bit bus transceivers. It is designed for high-speed data transmission in environments where voltage domain isolation is necessary. The DGVRG4 designation specifies the tape-and-reel packaging format suitable for automated assembly processes in high-volume manufacturing lines.

Replacement Considerations

Direct replacements include SN74LVC16T245DLR or SN74LVC16T245DGR, provided the package footprint matches the target board layout. Verify pin-to-pin compatibility and electrical specifications such as propagation delay and output current drive capabilities before substitution.
