CD74LPT16952ASM

Overview

The CD74LPT16952ASM is a dual 8-bit registered bus transceiver from the LPT series, manufactured by Harris Corporation. It operates on a single 3.3V supply and features 3-state outputs with independent control for each direction. The device utilizes a 56-pin SSOP plastic package and supports bidirectional data transfer. It functions as a non-inverting transceiver with true output polarity, designed for high-speed applications within an operating temperature range of -40°C to 85°C.

Feature Summary

• Dual 8-bit registered bus transceiver architecture
• Independent control for each transmission direction
• 3-state output capability for bus line management
• Non-inverting signal transmission

Applications

• High-speed data bus interfaces
• Memory buffer applications
• Bidirectional data gate circuits
• Registered data transmission systems

Procurement Notes

Verify the specific manufacturer source, as Harris Corporation assets were acquired by Renesas Electronics. Confirm the package type matches the required 56-pin SSOP form factor. Ensure the voltage level corresponds to the 3.3V specification. Check for RoHS compliance status, as original documentation may indicate non-compliance depending on the production era. Validate pinout compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component when a dual 8-bit registered transceiver is required for 3.3V logic systems. It is suitable for designs needing independent directional control and 3-state outputs. Compare propagation delay specifications against system timing requirements. Ensure the 56-pin SSOP package fits the available board space. Consider thermal performance within the specified industrial temperature range.

Part Context

This part belongs to the LPT (Low Power Technology) series of CMOS logic devices. It is functionally similar to other dual 8-bit registered transceivers but optimized for 3.3V operation. The device integrates registration capabilities to stabilize data during transmission. It serves as a bridge between different logic domains or memory subsystems in digital circuits.

Replacement Considerations

Check for equivalents such as the CD74LPT16952BMT which shares similar electrical characteristics but differs in package type. Verify pin-to-pin compatibility before substitution. Ensure the replacement maintains the 3.3V operating voltage and 3-state output functionality.
