SN74HC245PWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC245PWRE4 is an octal bus transceiver from the Texas Instruments HC logic series, housed in a 20-pin TSSOP package. It features bidirectional data transmission with common control and three-state outputs. The device operates within a supply voltage range of 2 V to 6 V and supports a low-level output current of 6 mA. It functions reliably across an industrial temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional octal data transfer between two ports controlled by a single direction signal.
• Outputs enter a high-impedance state when disabled, allowing safe parallel bus connections.
• CMOS input levels ensure compatibility with standard digital logic families.

Buffers, Drivers, Receivers, Transceivers Applications

• Mobile applications requiring low power consumption
• Clock driving and buffer applications
• Memory and address bus drives

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the component matches the specific SN74HC245PWRE4 designation to ensure correct package type and lead-free status. Confirm that the operating environment stays within the specified voltage and temperature limits. Check for RoHS compliance documentation if required for your assembly process. Ensure static-sensitive handling procedures are followed during installation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal wide-bus interface is needed with moderate speed requirements. The HC series offers a balance of speed and power consumption suitable for general-purpose logic applications. Consider the TSSOP package constraints regarding thermal dissipation and board space. Verify that the 6 mA drive capability meets the load requirements of the connected circuitry.
