74ACTQ16373SSCX

Latches Overview

The onsemi 74ACTQ16373SSCX is a 16-bit transparent latch with 3-state outputs, manufactured using Fairchild’s 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 operation. Key electrical parameters include a propagation delay (Dn to On) of up to 7.9 ns at 25°C and 8.4 ns at extended temperatures under 50 pF load. Output drive capability is rated at 24 mA source/sink current. Pin-to-pin output skew is guaranteed at 4.0 ns maximum.

Latches Feature Summary

• Utilizes FACT Quiet Series technology for superior dynamic threshold performance and guaranteed quiet output switching.
• 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 predictable system timing.

Latches Applications

• Bus-oriented applications requiring byte-controlled data latching
• High-density memory systems utilizing 16-bit data paths
• Digital signal processing interfaces requiring low-noise switching

Latches Procurement Notes

Verify the specific ordering suffix 'X' indicates tape and reel packaging as documented in the datasheet. Confirm that the SSOP package variant corresponds to the MS48A package number. Ensure compatibility with 4.5V to 5.5V supply rails before integration. Check for any RoHS compliance documentation updates relative to the original Fairchild Semiconductor manufacturing origin.

Latches Selection Notes

Select this component when byte-controllable 16-bit latching with 3-state outputs is required. The device is suitable for systems needing guaranteed simultaneous switching noise reduction. Consider the 48-lead SSOP form factor for space-constrained designs. Verify that the 5V logic family aligns with the system's input/output voltage requirements.

Latches Part Context

This part belongs to the 74ACT series of high-speed CMOS logic devices. It serves as the 16-bit counterpart to the 8-bit ACTQ373. The device integrates sixteen D-type latches with standard 3-state outputs, designed for bus-oriented applications where data transparency and controlled storage are critical.

Latches Replacement Considerations

The 74ACTQ373 serves as the 8-bit equivalent within the same logic family. For direct functional replacement, verify pin compatibility and ensure the substitute supports the required 16-bit width. Cross-reference package dimensions if transitioning between SSOP and TSSOP variants.
