74LVQ573MTR

Latches Overview

The STMicroelectronics 74LVQ573MTR is a low voltage CMOS octal D-type latch with non-inverting 3-state outputs. It operates within a supply voltage range of 2V to 3.6V and supports data retention at 1.2V. The device features high-speed performance with typical propagation delays of 5.8ns at 3.3V, balanced tPLH/tPHL characteristics, and symmetrical output impedance of 12mA minimum. It includes PCI bus level guarantees at 24mA, 75Ω transmission line driving capability, and enhanced latch-up immunity.

Latches Feature Summary

• Low power dissipation with maximum quiescent current of 4µA
• Low noise operation with dynamic low voltage quiet output specifications
• Pin and function compatible with standard 74 series 573 devices

Latches Applications

• Low power and low noise 3.3V applications
• PCI bus interface circuits
• Transmission line driving systems

Latches Procurement Notes

Verify the specific package type required for your design, as the MTR suffix indicates SOP-20 packaging. Confirm that the operating voltage range of 2V to 3.6V aligns with your system requirements. Ensure compatibility with TTL outputs if interfacing with legacy logic families. Check for RoHS compliance status in the latest manufacturer documentation before finalizing procurement.

Latches Selection Notes

Select this component when designing systems requiring octal latching with 3-state outputs in a low voltage environment. It is suitable for applications needing high-speed data transfer with minimal skew between outputs. Consider its pinout configuration which places inputs and outputs on opposite sides of the package to facilitate printed circuit board layout optimization.

Latches Part Context

This component belongs to the 74LVQ family of low voltage CMOS logic devices manufactured by STMicroelectronics. It utilizes sub-micron silicon gate and double-layer metal wiring C2MOS technology. The device provides improved latch-up immunity compared to earlier generations while maintaining functional compatibility with standard 74 series logic interfaces.

Latches Replacement Considerations

Direct substitutes include other manufacturers' 74LVQ573 variants or 74LCX573 equivalents. Verify pinout compatibility and electrical specifications such as propagation delay and output drive strength before substitution. Ensure the replacement part supports the required 3-state output functionality and low voltage operating range.
