AM29843DC

Latches Overview

The AM29843DC is a single-function, 9-bit D latch manufactured by Advanced Micro Devices. It utilizes TTL logic technology and is housed in a 24-pin Plastic Dual In-Line Package (PDIP). The device operates with a nominal supply voltage of 5 V and features 3-state outputs. Key electrical parameters include a maximum output current of 0.048 A, a typical propagation delay of 12 ns at nominal supply, and a maximum supply current of 97 mA. The component is rated for an operating temperature range from 0 °C to 70 °C.

Latches Feature Summary

• Provides 9-bit data storage capability within a single functional unit
• Features 3-state outputs for bus-compatible signal driving
• Utilizes standard TTL logic levels for interface compatibility

Latches Applications

• Parallel data buffering in digital systems
• Temporary data storage in microprocessor interfaces
• Address latching in memory subsystems

Latches Procurement Notes

Verify the package type matches the required 24-pin DIP configuration. Confirm that the TTL logic family and 5 V operating voltage align with the target circuit design. Ensure the commercial temperature range meets environmental requirements. Check for RoHS compliance status as indicated in manufacturer documentation.

Latches Selection Notes

Select this component when a 9-bit parallel latch with 3-state outputs is required. Ensure the system supports TTL logic levels and a 5 V power supply. Verify that the 12 ns propagation delay satisfies timing constraints. Consider the 24-pin DIP package for through-hole mounting applications.

Latches Part Context

This part belongs to the AMD AM29843 series of high-speed latches. The series offers various pin configurations and packages, including ceramic DIP and plastic DIP options. The AM29843DC specifically denotes the plastic dual in-line package variant. It is designed for general-purpose digital logic applications requiring reliable data storage and transfer.

Latches Replacement Considerations

Cross-reference with other AM29843 variants such as AM29843PC or AM29843DCB if different package materials are needed. Verify pinout compatibility before substituting with similar 9-bit latches from other manufacturers.
