SN74HCT245DBR Description

Short technical summary and product information.

The SN74HCT245DBR is an octal bus transceiver from Texas Instruments, part of the HCT logic family. It provides non-inverting data transmission between two bidirectional buses with 8 channels. The device operates from a supply voltage range of 4.5 V to 5.5 V and is fully specified for industrial temperature ranges from -40°C to 125°C.

 

Electrical characteristics include TTL-compatible input thresholds and CMOS output levels with a typical output drive of ±6 mA at 5 V. The inputs feature a positive clamp diode for ESD protection. Propagation delay is in the high-speed range of 10-50 ns. The device has balanced outputs and low input current of 1 µA maximum.

 

The SN74HCT245DBR is available in a 20-pin SSOP (Shrink Small Outline Package) for surface-mount assembly. It is commonly used for bus interfacing and data communication in industrial control, automotive, and general-purpose digital systems.
