74FCT841ASPC

Latches Overview

The National Semiconductor 74FCT841ASPC is a high-speed, 10-bit bus interface latch featuring non-inverting outputs with three-state control. Designed for F/FAST CMOS technology, it provides extra data width for wider address/data paths and buses carrying parity. The device utilizes a slim dual in-line package (PDIP-24) and offers pin-for-pin compatibility with AMD AM29841 series components. It includes buffered control inputs to reduce AC effects and features clamped inputs to handle positive and negative overshoots.

Latches Feature Summary

• Provides 10-bit parallel latching capability for wide address or data paths
• Features three-state outputs that remain glitch-free during power-up and power-down
• Incorporates buffered control inputs to minimize AC coupling effects
• Includes input clamping structures to tolerate voltage overshoots

Latches Applications

• High-speed parallel latching in computer systems
• Data buffering for buses carrying parity information
• Interface logic for MOS microprocessor systems requiring increased fan-in

Latches Procurement Notes

Verify the manufacturer origin as National Semiconductor, noting that this product line has transitioned through various corporate acquisitions. Confirm the specific suffix 'ASPC' corresponds to the intended PDIP-24 plastic package and commercial temperature range. Ensure the component meets the required RoHS compliance status if applicable to the current manufacturing batch, as legacy parts may have varying environmental certifications.

Latches Selection Notes

Select this component when a 10-bit non-inverting latch with three-state outputs is required for high-speed digital interfaces. It is suitable for applications needing pin-compatible replacement for AMD AM29841 devices. Consider its F/FAST CMOS speed characteristics and low input loading for driving multiple loads in complex bus architectures.

Latches Part Context

This part belongs to the 74FCT841 series of bus interface latches. These devices are functionally and pin-compatible with the AMD AM29841 series. They are designed to provide extra data width for wider address/data paths of buses carrying parity, making them essential for expanding data bus widths in high-performance computing environments.

Latches Replacement Considerations

The NXP Semiconductors N74F841N is a confirmed functional substitute. It shares identical pinout, functionality, and package type (PDIP-24). Verify that the substitute's electrical specifications align with the original National Semiconductor requirements.
