74ACT841SPC

Latches Overview

The onsemi 74ACT841SPC is a 10-bit transparent latch featuring non-inverting 3-STATE outputs. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. The device utilizes TTL-compatible inputs and provides output drive capabilities of 24 mA source/sink current. It is housed in a 24-Lead Plastic Dual-In-Line Package (PDIP).

Latches Feature Summary

• Features ten D-type latches with non-inverting 3-STATE outputs for bus interface applications.
• Provides TTL-compatible input thresholds for direct interfacing with standard logic families.
• Supports high-current output sourcing and sinking to drive wider address or data paths.

Latches Applications

• Bus interface systems requiring extra data width buffering.
• Address/data path expansion for parity carrying buses.
• General-purpose digital storage and latching circuits.

Latches Procurement Notes

Verify the specific package configuration, as the SPC suffix denotes the PDIP variant. Confirm that tape and reel availability does not apply to this specific ordering code, as datasheet documentation indicates the SPC version is not available in that packaging format. Ensure compatibility with the required 24-pin DIP footprint during procurement planning.

Latches Selection Notes

Select this component when a 10-bit transparent latch with 3-STATE outputs is required for bus buffering. It serves as a 10-bit equivalent to the ACT373, suitable for expanding data width. Verify that the system design accommodates the 24-pin PDIP package dimensions and meets the specified electrical requirements for the ACT family.

Latches Part Context

This part belongs to the 74ACT series of logic integrated circuits manufactured by Fairchild Semiconductor, now associated with onsemi. The 74ACT841 is specifically designed as a 10-bit transparent latch, functioning as a wider version of the 8-bit ACT373. It addresses the need for additional packages to buffer existing latches in systems requiring extended data paths.

Latches Replacement Considerations

The 74ACT841SC (SOIC) and 74ACT841MTC (TSSOP) are pin-compatible alternatives offering different package styles. These variants provide identical functional specifications but differ in physical mounting and footprint requirements compared to the PDIP SPC version.
