74ABT16841ADGG,112

Overview

The 74ABT16841ADGG,112 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 from -40°C to +85°C. The device utilizes a TSSOP56 package (SOT364-1) with 56 leads and a body width of 6.1mm. Key electrical characteristics include propagation delays of 3.1ns maximum for data inputs and 4.9ns maximum for latch enable inputs at VCC=5V. Output drive capabilities reach +64mA in the LOW state and -32mA in the HIGH state.

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 functionality
• Includes latch-up protection exceeding 500 mA per Jedec Std 17

Applications

• High-speed parallel latching applications
• Wide address/data path implementations
• Buses carrying parity information
• MOS microprocessor systems requiring high speed and light loading

Procurement Notes

Verify that the ordering suffix ',112' corresponds to the specific tube packaging variant listed in official Nexperia documentation. Confirm the component status as active or obsolete through current manufacturer channels, as standard product businesses may transition between entities like NXP and Nexperia. Ensure RoHS compliance requirements match the specific revision date of the datasheet used for design-in.

Selection Notes

Select this component when designing systems requiring 20-bit synchronous latching with 3-State output control. The ABT series offers high-speed performance suitable for MOS microprocessors. Consider the TSSOP56 package dimensions if board space is constrained. Verify that the input/output voltage levels align with the system's logic family and that the quiescent current specifications meet power budget requirements.

Part Context

This part belongs to the 74ABT logic family, known for high-speed CMOS technology. The 74ABT16841A is a 20-bit bus interface latch originally published by Philips Semiconductors. Following corporate restructuring, the Standard Product business became Nexperia B.V., which now manages these legacy and current logic products. The ADGG suffix specifically denotes the TSSOP56 plastic thin shrink small outline package.

Replacement Considerations

The 74ABT16841ADL is a pin-compatible alternative using the SSOP56 package. Check for updated revisions from Nexperia regarding equivalent parts if the original source is discontinued.
