74LVQ373TTR

Latches Overview

The STMicroelectronics 74LVQ373TTR is a low voltage CMOS octal D-type latch with 3-state non-inverting outputs. It operates within a supply voltage range of 2V to 3.6V, featuring balanced propagation delays and symmetrical output impedance. The device provides high-speed performance with typical propagation delays of 5.8 ns at 3.3V and supports PCI bus levels at 24 mA. It includes protection circuits against static discharge, ensuring 2kV ESD immunity.

Latches Feature Summary

• Octal D-type latch architecture with 3-state non-inverting outputs controlled by latch enable and output enable inputs.
• High-speed operation with balanced propagation delays and symmetrical output drive capability.
• Low power dissipation with minimal quiescent current consumption.

Latches Procurement Notes

Verify the specific ordering suffix 'TTR' corresponds to the TSSOP-20 tape and reel packaging configuration as defined in the official datasheet order codes. Confirm that the component meets RoHS compliance requirements for your region. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the STMicroelectronics product.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for 3.3V logic systems. It is suitable for designs needing high-speed data latching with low power consumption. Consider its compatibility with TTL outputs and its ability to drive transmission lines. Verify that the operating voltage range of 2V to 3.6V aligns with the system's power supply specifications.

Latches Part Context

The 74LVQ373 belongs to the LVQ series of low voltage CMOS logic devices from STMicroelectronics. This series is designed for applications requiring high speed and low power consumption. The 74LVQ373 specifically provides octal latching functionality with 3-state outputs, making it distinct from standard 74-series latches by offering improved performance in low voltage environments.

Latches Replacement Considerations

Check for pin-compatible alternatives within the 74LVX or 74LVC families if availability is an issue. Ensure any substitute maintains the 3-state output functionality and similar propagation delay characteristics. Verify that the replacement part supports the required 3.3V operating voltage and PCI bus level drive capabilities.
