74ALVC16373DTR

Latches Overview

The onsemi 74ALVC16373DTR is a low-voltage, non-inverting 16-bit transparent latch featuring 3-state outputs with 3.6 V tolerance. Designed for high-speed operation in 1.8 V, 2.5 V, or 3.3 V systems, it contains two independent 8-bit sections. Each section has separate Latch Enable (LEn) and Output Enable (OEn) inputs. The device operates within a supply voltage range of 1.65 V to 3.6 V. Propagation delays are 3.6 ns max at 3.0–3.6 V, 4.5 ns max at 2.3–2.7 V, and 6.8 ns max at 1.65–1.95 V. It supports live insertion and withdrawal, offers near-zero static supply current (40 µA), and includes IOFF specifications for high impedance when VCC = 0 V.

Latches Feature Summary

• Features 3.6 V-tolerant inputs and outputs for interfacing with mixed-voltage logic systems.
• Provides byte-controlled architecture with independent Latch Enable and Output Enable inputs for each 8-bit section.
• Supports live insertion and withdrawal operations through dedicated IOFF circuitry that guarantees high-impedance states when power is removed.

Latches Applications

• High-speed bus-oriented applications requiring byte-level control
• Mixed 3.3 V and 5 V system environments
• Live insertion and withdrawal data storage

Latches Procurement Notes

Verify the DT suffix indicates TSSOP-48 packaging and Tape & Reel shipping configuration. Confirm the component meets RoHS standards and Moisture Sensitivity Level 1 requirements. Ensure compatibility with the specified operating temperature range of -40°C to +85°C. Check for specific assembly and wafer lot markings if traceability is required for your manufacturing process.

Latches Selection Notes

Select this component for designs requiring low-power, high-speed latching in low-voltage environments. It is suitable for applications needing 3.6 V tolerance without level shifting. Consider the independent byte control for flexible data management. Verify that the TSSOP-48 package fits your PCB layout constraints and that the tape and reel format aligns with your automated assembly equipment.

Latches Part Context

This part belongs to the 74ALVC series of advanced low-voltage CMOS logic devices. It functions as a 16-bit transparent latch with 3-state outputs. The device is designed to operate efficiently in 1.8 V, 2.5 V, and 3.3 V systems, offering high speed and low power consumption. It serves as a second source to industry standard equivalents, ensuring broad compatibility in electronic designs.

Latches Replacement Considerations

Check for direct pin-compatible alternatives from other manufacturers within the 74ALVC16373 family. Verify electrical characteristics such as propagation delay and output drive current match your design requirements. Ensure the replacement component supports the same 3.6 V tolerance and operates within the required voltage and temperature ranges.
