SN74ALS651ANTG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS651ANTG4 is an octal bus transceiver and register from Texas Instruments' ALS logic family. It features eight-bit data paths with three-state outputs, designed for high-speed bidirectional data transfer between buses. The device operates within a supply voltage range of 4.5V to 5.5V and utilizes a 24-pin DIP package. Key electrical characteristics include a propagation delay of approximately 14ns and output current capabilities suitable for driving standard TTL loads.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bus transceiver architecture supporting bidirectional data flow
• Three-state outputs for effective bus isolation and line sharing
• Inverting logic configuration for signal phase management

• General-purpose digital logic applications needing bus isolation

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify RoHS compliance status as the base SN74ALS651 series may not meet current environmental standards. Confirm package integrity upon receipt, as DIP packages are susceptible to pin damage during shipping. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent internal die damage before soldering.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with three-state control is required for ALS speed performance. Compare against SN74ALS651 variants to determine if specific suffixes indicate different packaging or environmental certifications. Verify that the inverting nature aligns with system logic requirements without additional inversion stages.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74ALS651 family of octal bus transceivers. It shares functional similarities with the SN74AS651NT but differs in speed and power consumption characteristics typical of the Advanced Low-power Schottky (ALS) technology. The 'ANTG4' suffix denotes the specific 24-pin DIP package and lead-free manufacturing process.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the SN74ALS651ANT and SN74ALS651-1NT3. Verify pin compatibility and electrical specifications before replacing. Note that some variants may have different RoHS statuses or package tolerances.
