74ALVCH16841DGGS

Overview

The Nexperia 74ALVCH16841DGGS is a 20-bit bus interface D-type latch featuring two independent 10-bit registers with 3-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V and supports current drive of ±24 mA at VCC = 3.0 V. The device utilizes a TSSOP56 (SOT364-1) package and includes active bus hold circuitry on all data inputs to maintain valid logic levels without external resistors. It complies with JEDEC standards JESD8-5 and JESD8B/JESD36, ensuring direct interface compatibility with TTL levels.

Feature Summary

• Features MULTIBYTE flow-through standard pin-out architecture for simplified bus-oriented applications.
• Includes active bus hold circuitry on all data inputs to eliminate the need for external pull-up or pull-down resistors.
• Designed with low inductance multiple VCC and GND pins to minimize noise and ground bounce effects.

Applications

• Bus oriented applications requiring 3-state non-inverting outputs
• Memory systems utilizing 20-bit data latching
• Mixed voltage environments interfacing with TTL logic levels

Procurement Notes

Verify component authenticity through authorized Nexperia distributors or official channels. Confirm the specific ordering suffix matches the required package variant. Check the latest product status documentation as availability may change. Ensure compliance with RoHS directives and REACH regulations relevant to your region before integration into final designs.

Selection Notes

Select this component when designing systems requiring high-density 20-bit latching with bus tri-stating capabilities. The ALVCH series is suitable for mixed-voltage interfaces due to its wide supply range and TTL compatibility. Consider the TSSOP56 package constraints regarding board space and thermal dissipation requirements during layout planning.

Part Context

This part belongs to the Nexperia 74ALVCH logic family, which provides advanced low voltage CMOS performance.
