74ALVT16821DL,512

Overview

The 74ALVT16821DL,512 is a high-performance BiCMOS device from the 74ALVCH series, designed for VCC operation at 2.3V to 2.7V and 3V to 3.6V. It features two 10-bit D-type flip-flops with positive-edge triggering in a 56-SSOP package. Key electrical parameters include a maximum propagation delay of 4.5ns at 3.3V with 50pF load, a clock frequency of 350 MHz, and static current (Iq) of 40 µA. Output drive capabilities are specified as 24mA for both high and low states, with an input capacitance of 5 pF. The device operates within a temperature range of -40°C to 85°C.

Feature Summary

• Features two independent 10-bit edge-triggered registers coupled to 3-state output buffers.
• Provides I/O compatibility to 5V while operating at lower supply voltages.

Applications

• High-speed data bus interface systems
• Parallel data storage and transfer applications
• Digital signal processing interfaces

Procurement Notes

Verify component status carefully as this part may be marked as obsolete or not recommended for new designs. Confirm availability through authorized Nexperia distributors or secondary market suppliers. Ensure that the specific ordering suffix matches required packaging and tape/reel specifications. Check for any product change notifications regarding pinout or electrical characteristics before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring 20-bit parallel data latching with high-speed performance at 3.3V logic levels. Consider the 56-pin SSOP package constraints for PCB layout. Evaluate the 4.5ns propagation delay against system timing requirements. Ensure voltage levels align with the specified 2.3V-2.7V and 3V-3.6V ranges for optimal operation.

Part Context

This device belongs to the 74ALVCH family, which utilizes Advanced Low-Voltage CMOS Hybrid technology. It serves as a bus-interface register suitable for applications demanding fast switching speeds and low power consumption. The 74ALVT16821DL,512 is distinct from similar ALVT parts by its specific latch functionality and lack of integrated termination resistors found in other variants like the 74ALVT162821.
