SN74ALVC245PWG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVC245PWG4 is an octal bus transceiver from Texas Instruments' ALVC logic family, housed in a 20-pin TSSOP package. It features three-state outputs and bidirectional data transfer capability controlled by a direction pin. The device operates within a supply voltage range of 1.2V to 3.6V, supporting low-voltage CMOS and TTL logic levels. Key electrical parameters include a maximum propagation delay of 3.8ns at specific load conditions, with output drive capabilities of 12mA for both high and low states. It functions reliably across an industrial temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the G4 suffix, which indicates lead-free status and RoHS compliance. Confirm the TSSOP-20 package variant matches your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power rails before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed performance is required alongside low-voltage operation. The ALVC series offers faster switching speeds compared to standard LVC or HC families while maintaining compatibility with 3.3V and 5V systems. Consider the 20-pin TSSOP form factor for space-constrained surface-mount designs.
