SN74HC245DWRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC245DWRG4 is an octal bus transceiver from the Texas Instruments HC logic family, housed in a 20-pin SOIC package. It features three-state outputs and operates within a supply voltage range of 2 V to 6 V. The device provides a low-level output current of 6 mA and a high-level output current of -6 mA. Propagation delay is specified at 22 ns. It supports CMOS input and output levels and functions within a temperature range of -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight bidirectional data channels for parallel bus interfacing
• Three-state outputs allowing direct connection to system buses without additional drivers
• CMOS-compatible input and output levels ensuring compatibility with standard logic families

Buffers, Drivers, Receivers, Transceivers Applications

• Mobile applications requiring low power consumption and wide voltage operation
• Clock driving and buffer applications in digital systems
• High noise immunity industrial control systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the G4 suffix indicates lead-free and halogen-free compliance per RoHS standards. Confirm the DWR suffix corresponds to the SOIC-20 tape and reel packaging format. Ensure the component matches the specific HC series electrical characteristics rather than ACT or AHC variants.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with a wide 2 V to 6 V operating range is required. The HC series offers higher speed than standard LS logic while maintaining lower power consumption. Verify that the 22 ns propagation delay meets the system timing requirements compared to faster AHC or LVC alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HC245 family of octal bus transceivers. It serves as a standard interface solution for connecting microprocessors to memory or peripheral devices. The device is designed for general-purpose digital applications requiring reliable bidirectional data transfer across multiple lines simultaneously.
