74ACTQ16373SSC

Latches Overview

The onsemi 74ACTQ16373SSC is a 16-bit transparent latch with 3-state outputs, manufactured using FACT Quiet Series technology. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. The device features separate control logic for each byte, ensuring independent functionality. Propagation delays are guaranteed at specific limits under defined load conditions.

Latches Feature Summary

• Utilizes FACT Quiet Series technology for quiet output switching and improved dynamic threshold performance.
• Features separate control logic for each byte, allowing independent operation or combined full 16-bit functionality.
• Guarantees simultaneous switching noise levels and pin-to-pin output skew for superior signal integrity.

Latches Applications

• Bus-oriented applications requiring byte-controlled data storage
• High-speed digital systems utilizing ACT logic families
• Memory interface circuits demanding low noise characteristics

Latches Procurement Notes

Verify the package designation MS48A corresponds to the 48-Lead Small Shrink Outline Package (SSOP). Confirm that the ordering code matches the specific suffix requirements if tape and reel packaging is needed, which requires appending the letter X. Ensure compatibility with the 4.5V to 5.5V supply voltage range during system design validation.

Latches Selection Notes

Select this component for designs requiring 16-bit latching with high noise immunity. The separate byte control allows flexible configuration for different bus widths. Verify that the required propagation delay specifications align with the system timing constraints under the expected load capacitance and temperature conditions.

Latches Part Context

This part belongs to the 74ACT series of high-speed CMOS logic devices. It serves as a 16-bit version of the 8-bit ACTQ373 latch. The device is designed for applications needing robust performance in noisy environments due to its specialized output control technology.

Latches Replacement Considerations

The 74ACTQ16373MTD is available in a TSSOP-48 package. Verify pinout compatibility before substitution. Check if the alternative package meets the physical space constraints of the original design.

Latches FAQ

How does the device handle byte control?

The device contains sixteen D-type latches divided into two bytes. Each byte has independent Latch Enable and Output Enable inputs, allowing them to function identically but independently of each other.

What is the purpose of the FACT Quiet Series technology?

It guarantees quiet output switching and improved dynamic threshold performance, reducing simultaneous switching noise and ensuring stable operation in high-density digital systems.
