74ALVCH16823DGG,11

Overview

The Nexperia 74ALVCH16823DGG,11 is a dual 9-bit D-type transparent latch with 3-state outputs, housed in a 56-TSSOP package. It operates within a supply voltage range of 2.3 V to 3.6 V and supports an operating temperature range from -40 °C to +85 °C. The device features a propagation delay of 2.2 ns and provides output drive currents of 24 mA for both high and low states. It includes a master reset function and complies with RoHS3 standards.

Feature Summary

• Dual 9-bit transparent latch architecture with independent control
• 3-state outputs for efficient bus line driving
• Master reset functionality for system initialization
• Partial power-down capability via I_OFF circuitry

Applications

• High-speed data buffering in digital systems
• I/O port expansion for microcontrollers
• Memory address latching applications
• Parallel data interface management

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Production has ceased, and no new units are available from primary sources. Procurement efforts should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm lot dates and storage conditions carefully due to the discontinued status.

Selection Notes

Engineers requiring this specific logic family should evaluate the 74ALVCH16823DGGY variant as a potential alternative, though availability may also be limited. Design reviews should assess if newer generation components offer equivalent pinouts and electrical characteristics to ensure long-term supply chain stability for ongoing production projects.

Part Context

The 74ALVCH16823 belongs to the ALVCH series, designed for 3.3 V applications with high-speed performance. This specific part number represents a dual 9-bit latch configuration, distinct from similar 16-bit variants like the 74ALVCH16824. It serves as a core memory element in complex digital logic circuits requiring parallel data retention.

Replacement Considerations

The 74ALVCH16823DGGY is listed as a direct substitute part number.
