74ABT16841ADL,518

Overview

The 74ABT16841ADL,518 is a 20-bit bus interface latch featuring two sets of ten D-type latches with 3-State outputs. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of -40°C to +85°C. The device provides high-speed parallel latching capabilities with propagation delays as low as 1.0ns from Latch Enable to output. Output drive capability reaches +64mA for LOW state and -32mA for HIGH state. It includes power-up 3-State functionality and reset features.

Feature Summary

• Provides extra data width for wide address/data paths or buses carrying parity
• Permits live insertion and extraction operations
• Features power-up 3-State and power-up reset mechanisms

Applications

• High speed MOS microprocessor systems requiring light loading
• Wide address/data path implementations
• Buses carrying parity information

Selection Notes

Select this component when designing systems that require expanded data width beyond standard 8-bit or 16-bit interfaces. The 3-State outputs facilitate bus sharing in complex architectures. Ensure the design accommodates the required 4.5V to 5.5V supply voltage and considers the SSOP56 package thermal characteristics for the target operating environment.

Part Context

This part belongs to the 74ABT logic family, known for high-speed performance compatible with CMOS technologies. The manufacturer transitioned from Philips Semiconductors/NXP to Nexperia, which now manages the product line. The datasheet indicates it replaces earlier versions like the 74ABTH16841A, maintaining functional compatibility while updating manufacturing standards.

Replacement Considerations

The 74ABT16841ADGG is a direct pin-compatible alternative using a TSSOP56 package instead of SSOP56. Both variants share identical electrical specifications and logical functions, allowing for substitution based on board space requirements.
