SN74ALS646ANT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS646ANT is an octal registered bus transceiver from the Texas Instruments ALS logic family. It features eight non-inverting data paths with TTL-compatible input and output levels. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides three-state outputs with a low-level output current of 24 mA and a high-level output current of -15 mA. Propagation delay is specified at 30 ns. The component supports surface mount installation in a SOIC-24 package and functions within a temperature range of 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A' against official manufacturer documentation, as standard listings typically reference the SN74ALS646ADW variant. Confirm that the SOIC-24 package matches the required footprint for the design. Ensure the commercial temperature range aligns with operational requirements before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal registered transceiver with ALS speed and power characteristics is required. The TTL input compatibility simplifies interfacing with legacy logic families. Verify that the 30 ns propagation delay meets system timing constraints and that the 24 mA drive capability is sufficient for the connected load.
