AM29825PC

Shift Registers Overview

The AM29825PC is an octal bus driver from the S Series, manufactured by Advanced Micro Devices. It features 8-bit data width with true output polarity and TTL logic compatibility. The device utilizes a 24-pin plastic DIP (PDIP24) slim package. Key electrical characteristics include a maximum operating frequency of 71 MHz and a maximum output current of 0.048 A. It supports three-state outputs and operates within a temperature range up to 70 °C.

Shift Registers Feature Summary

• Octal bus driver architecture providing 8-bit parallel data transmission capability
• Three-state output configuration allowing for controlled signal isolation on shared buses
• True output polarity ensuring non-inverted signal transfer relative to inputs
• TTL logic compatibility enabling integration with standard transistor-transistor logic systems

Shift Registers Applications

• High-speed data bus buffering in computer architectures
• Clock distribution networks requiring precise signal integrity
• Memory interface circuits for address and data line driving
• Industrial control systems utilizing TTL-based logic controllers

Shift Registers Procurement Notes

Verify the specific suffix 'PC' against manufacturer documentation to confirm the plastic DIP package variant and ensure it matches the required lead material and thermal specifications. Confirm RoHS compliance status as historical AMD parts may not meet modern environmental standards. Cross-reference the pinout diagram with the target PCB footprint to prevent orientation errors during assembly.

Shift Registers Selection Notes

Select this component when an 8-bit wide bus driver with true output polarity is required for TTL-compatible systems. The 71 MHz frequency rating suits moderate-speed digital applications. Ensure the design accommodates the 24-pin PDIP form factor and that the load capacitance requirements remain within the specified 50 pF limit for reliable switching performance.

Shift Registers Part Context

This part belongs to the AMD S Series family of high-speed logic devices. These components were designed for early personal computer and workstation architectures. The AM29825 variant specifically addresses the need for octal buffering with tri-state capabilities, distinguishing it from hex or quad drivers in the same product lineage.
