74VCX16373TTR

Latches Overview

The STMicroelectronics 74VCX16373TTR is a low-voltage CMOS 16-bit D-type latch with three-state outputs, fabricated using sub-micron silicon gate and five-layer metal wiring C2MOS technology. It operates within a supply voltage range of 1.8V to 3.6V and features 3.6V tolerant inputs and outputs. The device includes power-down protection on both inputs and outputs, ensuring high impedance states during power-off conditions. It offers symmetrical output impedance capabilities and exhibits latch-up performance exceeding 300mA per JESD 17 standards. ESD protection ratings include HBM greater than 2000V and MM greater than 200V.

Latches Feature Summary

• Features 3.6V tolerant inputs and outputs for interfacing with higher voltage signal environments.
• Provides power-down protection on inputs and outputs to maintain high impedance states.
• Delivers high-speed operation with propagation delays as low as 3.0 ns at VCC = 3.0 to 3.6 V.
• Ensures robust reliability with latch-up performance exceeding 300mA and significant ESD immunity.

Latches Applications

• Low power and very high speed 1.8 to 3.6V applications
• Interfacing between 1.8V logic and 3.6V signal environments
• Data bus latching in portable electronic devices

Latches Procurement Notes

Verify the specific ordering code matches the required package type, as the TTR suffix indicates Tape and Reel packaging in TSSOP-48 format. Confirm that the application environment strictly adheres to the specified operating voltage range of 1.8V to 3.6V to ensure optimal performance and longevity. Ensure that input signals do not exceed the absolute maximum ratings defined in the datasheet to prevent damage to the internal protection circuits.

Latches Selection Notes

Select this component when designing systems requiring 16-bit data storage with tri-state control in low-voltage environments. It is suitable for applications needing direct interfacing with 3.6V buses while operating at lower core voltages. Consider its high-speed characteristics for timing-critical designs where propagation delay impacts system performance. Evaluate the TSSOP-48 package constraints against available PCB space and thermal management requirements.

Latches Part Context

This part belongs to the 74VCX series of low-voltage CMOS logic devices from STMicroelectronics. It maintains pin and function compatibility with standard 74 series 16373 components, facilitating drop-in replacements in existing designs. The series utilizes advanced C2MOS technology to achieve high speed and low power consumption simultaneously, targeting modern portable and battery-operated electronics.

Latches Replacement Considerations

Check for functional equivalence with other 16-bit D-type latches featuring three-state outputs. Verify that any substitute component supports the same 1.8V to 3.6V operating range and 3.6V tolerance. Ensure the replacement package matches the TSSOP-48 form factor if board space is constrained.
