SN74ALS623ADWRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS623ADWRG4 is an octal bus transceiver from the Texas Instruments SN74ALS series. It operates within a supply voltage range of 4.5 V to 5.5 V and features three-state outputs. The device supports bidirectional data transfer between two buses, controlled by direction and output enable inputs. It is housed in a 20-pin SOIC package with a wide-body option available. The component is designed for high-speed applications requiring low power consumption typical of the Advanced Low-power Schottky logic family.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transmission capability between two independent buses
• Features three-state outputs that isolate the bus when disabled
• Operates on a single 5 V supply voltage rail
• Supports high-speed switching with low power dissipation characteristics

• Memory mapping controllers
• Clock drivers
• Bus-oriented communications systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix G4 indicates lead-free packaging compliant with RoHS standards. Confirm the SOIC-20 package dimensions match the design footprint requirements. Ensure the operating temperature range aligns with the system environment specifications before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring octal bus isolation with bidirectional control. Compare propagation delay specifications against system timing constraints. Evaluate power dissipation limits relative to the thermal management capabilities of the target PCB layout and enclosure design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ALS logic family, known for improved speed and power efficiency over standard LS logic. The SN74ALS623A variant specifically offers bidirectional functionality with separate direction control, distinguishing it from unidirectional buffers or latches within the same series classification.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74ALS623ADW as a direct equivalent without the lead-free suffix. Verify compatibility with SN74ALS623AP if through-hole packaging is acceptable. Confirm functional equivalence with other ALS octal bus transceivers regarding pinout and electrical characteristics.
