74ABT841D,623

Latches Overview

The NXP USA Inc. 74ABT841D,623 is a high-performance BiCMOS 10-bit bus interface register featuring 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 of -40 °C to +85 °C. The device provides an output capability of +64 mA and -32 mA, ensuring robust drive strength for wide data or address paths. Propagation delays from data input to output range from 2.0 ns to 6.2 ns depending on conditions, while latch enable to output delays range from 2.1 ns to 6.7 ns. The component utilizes a 24-lead SO plastic small outline package (SOT137-1) with a body width of 7.5 mm.

Latches Feature Summary

• Provides extra data width for wider data/address paths or buses carrying parity
• Features high-speed parallel latching with asynchronous operation capabilities
• Includes power-up 3-state functionality and power-up reset mechanisms
• Offers enhanced ESD protection exceeding 2000 V per Human Body Model

Latches Applications

• Wide data or address path expansion in MOS microprocessor systems
• Bus interface applications requiring increased fan-in
• Systems demanding high speed and light loading conditions

Latches Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the base part number corresponds to the SO24 package. Confirm that the '623' suffix aligns with current manufacturing specifications and availability status. Ensure compatibility with the intended operating temperature range and supply voltage requirements before finalizing procurement decisions.

Latches Selection Notes

Select this component when expanding bus width for parity-carrying paths or increasing fan-in in high-speed digital designs. The 10-bit configuration suits applications needing more than standard octal latches without utilizing multiple devices. Consider the 3-state output control and high drive current for interfacing with heavy loads or long traces in system architectures.

Latches Part Context

This device belongs to the 74ABT series of high-performance BiCMOS logic components manufactured by NXP Semiconductors. The series is characterized by low static and dynamic power dissipation combined with high speed. The 74ABT841 specifically addresses needs for bus interface registers with extended data width capabilities compared to standard 8-bit variants.

Latches Replacement Considerations

Consult official NXP documentation for direct pin-compatible substitutes. Verify functional equivalence regarding latch enable and output enable logic levels if replacing with similar 10-bit bus interface latches from other manufacturers.
