74ABT16823ADL,518

Flip Flops Overview

The 74ABT16823ADL,518 is an 18-bit bus interface D-type flip-flop with reset and enable functions, manufactured by NXP USA Inc. It features positive edge-triggered D-type flip-flops designed for high-speed parallel registers. The device supports live insertion/extraction and includes power-up 3-State capability. It incorporates bus-hold data inputs to eliminate external pull-up resistors for unused inputs and offers a power-up reset function. Output capability is specified at +64mA/-32mA, with latch-up protection exceeding 500mA per JEDEC Std 17.

Flip Flops Procurement Notes

Verify the specific ordering suffix ,518 corresponds to the SOT962-1 VFBGA64 reel dry pack configuration as documented in NXP packaging standards. Confirm that the part number matches the exact 18-bit bus interface specification. Ensure compatibility with existing system designs regarding the positive edge-triggered logic and bus-hold input requirements. Check for any obsolescence notices or end-of-life notifications from the manufacturer before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when designing systems that require 18-bit wide data buses with synchronous registration. It is suitable for applications needing high-speed performance and light loading characteristics compatible with MOS microprocessors. The inclusion of bus-hold inputs simplifies design by removing the need for external pull-up resistors on unused lines. Consider the +64mA/-32mA output drive strength and ESD protection levels when evaluating signal integrity and robustness requirements for the target application environment.

Flip Flops Part Context

This component belongs to the 74ABT series of advanced BJT technology logic devices, which are designed for high-speed digital applications. The 74ABT16823A variant specifically addresses the need for wider data paths in bus architectures. It serves as a register buffer to eliminate extra packages required for buffering existing registers. The device is part of NXP's portfolio of standard logic components aimed at improving system density and performance in complex digital circuits.

Flip Flops Replacement Considerations

Similar parts include the BT16821ADGG and BT16821ADL, though these are 20-bit variants rather than 18-bit. Verify pinout and bit-width compatibility when considering substitutes. No direct public confirmed substitute part numbers are explicitly listed for this specific 18-bit model in the provided documentation.
