SN74ALS653DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS653DW is an octal bus transceiver and register manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input and output levels. The device provides three-state outputs with low-level output current of 24 mA and high-level output current of -15 mA. It exhibits a propagation delay of 64 ns and functions in an inverting polarity. Designed for surface mount installation, it is housed in a SOIC-24 package and supports an operating temperature range from 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through current datasheets as regulatory requirements may vary by production batch. Ensure the selected variant matches the required industrial or commercial temperature ratings for the intended application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal interface requires simultaneous latching and bidirectional transmission capabilities. The ALS series offers improved speed-power product compared to standard TTL variants. Verify that the system voltage remains strictly within the 4.5 V to 5.5 V range to maintain signal integrity and prevent device damage.

Buffers, Drivers, Receivers, Transceivers Part Context
