74ABT841PW,112

Latches Overview

The NXP 74ABT841PW,112 is a high-performance BiCMOS 10-bit bus interface latch featuring 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 provides output drive capabilities of +64 mA (LOW) and -32 mA (HIGH). Propagation delays are specified with maximum values up to 6.7 ns depending on the signal path. It includes power-up 3-state functionality and power-up reset features.

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 JESD78B class II level A
• Offers ESD protection exceeding 2000 V (HBM) and 200 V (MM)

Latches Applications

• Bus interface registers requiring extra data width
• Wide address/data paths carrying parity
• Applications requiring high speed, light loading, or increased fan-in with MOS microprocessors

Latches Procurement Notes

Verify the package type matches the specific suffix requirements for your design. Confirm that the operating conditions align with your system's voltage and temperature specifications. Ensure proper handling procedures are followed due to the sensitivity of the BiCMOS technology. Check for any specific ordering information updates from the manufacturer before finalizing procurement.

Latches Selection Notes

Select this component when designing systems that require expanded data bus widths or parity checking capabilities. It is suitable for applications needing high-speed parallel latching with strong output drive currents. Consider the TSSOP24 package constraints and ensure thermal management meets the recommended operating conditions for reliable performance in varying environments.

Latches Part Context

The 74ABT841 belongs to the ABT series of high-performance BiCMOS logic devices manufactured by NXP Semiconductors. This series combines low static and dynamic power dissipation with high speed and high output drive capabilities. The 74ABT841 specifically functions as a 10-bit bus interface latch, designed to enhance data width for complex bus architectures.

Latches Replacement Considerations

The datasheet lists the 74ABT841D and 74ABT841DB as alternative package versions of the same functional device. Verify pinout compatibility and package dimensions when substituting between SO24, SSOP24, and TSSOP24 variants.
