SN74HC245NSRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC245NSRE4 is an octal bus transceiver from the Texas Instruments HC logic family, designed for bidirectional data communication. It features eight non-inverting channels with three-state outputs and operates within a supply voltage range of 2 V to 6 V. The device utilizes CMOS input and output levels and provides a low-level output current of 6 mA and a high-level output current of -6 mA. It exhibits a propagation delay of 22 ns and functions reliably across an operating temperature range of -40°C to +85°C. Packaged in a 20-pin SOIC format, it supports surface-mount installation.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix RE4 indicates tape and reel packaging when sourcing. Confirm the NS package designation corresponds to the SOIC-20 form factor required for your printed circuit board layout. Ensure compatibility with standard HC logic voltage levels and check RoHS compliance documentation for regulatory requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring eight-bit wide bidirectional data transfer with high impedance states. Consider the SOIC-20 package dimensions for space constraints. Evaluate the 2V to 6V operating range against system power supplies. Compare propagation delay specifications if timing criticality exceeds 22 ns limits.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HC245 series of octal bus transceivers. It shares functional characteristics with variants like SN74HC245N and SN74HC245DWRE4, differing primarily in package type and shipping configuration.
