74ABT841DB,118

Latches Overview

The 74ABT841DB,118 is a high-performance BiCMOS bus interface register containing ten D-type latches with 3-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +85 °C. The device features low static and dynamic power dissipation combined with high output drive capability, providing +64 mA and -32 mA output currents. Propagation delays are specified between 2.0 ns and 6.7 ns depending on the signal path.

Latches Feature Summary

• Provides extra data width for wider address/data paths or buses carrying parity
• Features power-up 3-state and power-up reset capabilities
• Includes latch-up protection exceeding 500 mA per JEDEC Std 78B Class II Level A
• Offers ESD protection exceeding 2000 V per HBM JESD22-A114F

Latches Applications

• MOS microprocessor systems requiring high speed and light loading
• Applications demanding increased fan-in
• Bus interface registers for parity-carrying buses

Latches Procurement Notes

Verify the specific package variant against the ordering information table. The DB suffix indicates an SSOP-24 plastic shrink small outline package (SOT340-1) with a body width of 5.3 mm. Confirm that the required temperature range matches the -40 °C to +85 °C specification before finalizing procurement decisions.

Latches Selection Notes

Select this component when expanding data bus width is necessary for parity applications. It is suitable for designs requiring high-speed parallel latching with significant output drive strength. Ensure the system logic levels align with the recommended operating conditions for the ABT series.

Latches Part Context

This part belongs to the 74ABT series of high-performance BiCMOS logic devices manufactured by NXP Semiconductors. The 74ABT841 specifically functions as a 10-bit bus interface latch. Other variants in this family include the SO24 (74ABT841D) and TSSOP24 (74ABT841PW) packages.

Latches Replacement Considerations

Direct replacements include the 74ABT841D (SO24 package) and 74ABT841PW (TSSOP24 package). Verify pin compatibility and package dimensions when substituting these variants.
