SN74AS245DB

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS245DB is an octal bus transceiver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum propagation delay of 5.5 ns at 5 V. The device utilizes AS logic technology, providing PNP inputs that reduce DC loading on driving circuits. It supports asynchronous two-way communication between data buses via Direction (DIR) and Output Enable (OE) control inputs. The component is housed in a 20-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DB' corresponds to the SSOP-20 package configuration. Confirm the operating temperature range matches the application requirements, as catalog versions typically support 0°C to 70°C. Ensure compatibility with the 4.5 V to 5.5 V supply voltage specifications before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed octal data transfer with low input loading. The AS series offers faster switching speeds compared to standard ALS variants. Consider the SSOP package constraints regarding thermal dissipation and board space when integrating into the system layout.

Buffers, Drivers, Receivers, Transceivers Part Context
