74FCT841BSPC

Latches Overview

The National Semiconductor 74FCT841BSPC is a 10-bit bus interface latch belonging to the FCT logic series. It features non-inverting outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device provides high-speed parallel latching capabilities with a propagation delay of 13 ns at 5 V. It utilizes a QSOP-24 surface-mount package and supports low-level output currents of 32 mA and high-level output currents of -32 mA. Designed for industrial applications, it functions reliably across an operating temperature range from -40 °C to +85 °C.

Latches Feature Summary

• Provides extra data width for wider address/data paths or buses carrying parity
• Features high impedance NPN base input structure to minimize bus loading
• Includes buffered control inputs to reduce AC effects

Latches Applications

• High speed parallel latching in microprocessor systems
• Wider address/data path expansion for buses carrying parity
• Applications requiring high speed, light loading, or increased fan-in

Latches Procurement Notes

Verify the manufacturer designation carefully, as Texas Instruments acquired National Semiconductor's logic business. Confirm that the specific suffix corresponds to the QSOP-24 package and industrial temperature grade. Ensure compatibility with existing board layouts designed for the FCT series specifications before procurement.

Latches Selection Notes

Select this component when designing systems requiring 10-bit non-inverting latching with fast switching speeds. It serves as a functional and pin-compatible alternative to the AMD AM29841 series. Consider the 3-state output capability and power-off disable features if live insertion support is required for the target application architecture.

Latches Part Context

This part belongs to the 74FCT841/74F841 family of 10-bit bus interface latches. These devices are designed to provide additional data width for buses carrying parity. They are functionally and pin-compatible with the AMD AM29841 series, facilitating direct replacement in legacy designs while offering improved performance characteristics typical of the FCT logic family.

Latches Replacement Considerations

The 74FCT841BSPC is functionally and pin-for-pin compatible with the AMD AM29841 through AM29846 series. Verify that substitute components maintain the same 10-bit configuration and 3-state output behavior to ensure circuit integrity.
