SN74HCT652DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT652DW is an octal bus transceiver and register featuring three-state outputs, manufactured by Texas Instruments in a 24-pin SOIC package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels with HCT output compatibility. The device integrates D-type flip-flops for data storage, allowing selection between real-time transmission and stored data via control inputs. Key electrical parameters include a maximum propagation delay of 31 ns at 5 V, low quiescent current of 80 μA, and output drive capabilities of ±6 mA. It functions reliably across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrates octal bus transceiver circuitry with D-type flip-flops for simultaneous data transfer and storage
• Provides independent control over A and B buses through dedicated output enable and select inputs
• Supports multiplexed real-time and stored data transmission paths with true data path polarity
• Features high-current three-state outputs capable of driving multiple LSTTL loads

Buffers, Drivers, Receivers, Transceivers Applications

• Direct data bus multiplexing from internal storage registers
• System memory interface buffering with registered data paths
• Bidirectional bus isolation in microprocessor-based systems
• Data latching applications requiring tri-state output control

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' corresponds to the 24-pin SOIC package variant when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the selected component matches the required industrial temperature range specifications for your application environment prior to final procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring both bus transceiving and data registration capabilities within a single package. It is suitable for 5 V logic families needing TTL-compatible inputs. Consider the 31 ns propagation delay and ±6 mA drive strength against system timing requirements. Verify that the 24-pin SOIC footprint aligns with the target PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HCT652 series of octal registered transceivers. It shares functional similarities with other bus transceivers but distinguishes itself by integrating storage elements directly into the transceiver architecture. The HCT technology ensures compatibility with standard TTL logic levels while offering improved noise margins compared to older LS series devices.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include SN54HCT652J and SN74HCT652N. Verify pinout compatibility and package dimensions before substitution. Ensure voltage and temperature ranges match the original design requirements.
