74V1T77STR

Latches Overview

The 74V1T77STR is a single D-type latch manufactured by STMicroelectronics using advanced sub-micron silicon gate and double-layer metal wiring C2MOS technology. Designed for portable applications, it operates within a supply voltage range of 4.5V to 5.5V. The device features high-speed performance with a typical propagation delay of 4.7ns at VCC = 5V. It includes power-down protection on inputs, allowing 0V to 7V input levels regardless of the supply voltage, making it suitable for interfacing 5V systems to 3V environments.

Latches Feature Summary

• Advanced CMOS technology providing high speed and low power dissipation
• Power-down protection enabling safe interfacing between different voltage domains
• Symmetrical output impedance ensuring balanced signal transmission

Latches Applications

• Portable electronic devices requiring compact memory storage
• Data buffering in mixed-voltage logic circuits
• Signal latching in high-speed digital communication interfaces

Latches Procurement Notes

Verify that the component matches the specific SOT23-5L package configuration required for your PCB layout. Confirm the operating temperature range aligns with your system's environmental conditions. Ensure compatibility with your existing design tools and simulation models before finalizing the procurement order.

Latches Selection Notes

Select this component when a single D-type latch is needed in a minimal footprint. It is ideal for designs requiring interface between 5V and 3V logic levels without additional level shifting components. Consider its low quiescent current and high immunity to latch-up for robust operation in battery-powered or noise-sensitive applications.

Latches Part Context

This part belongs to the 74V series of high-speed CMOS logic devices from STMicroelectronics. It is functionally compatible with standard 74-series logic but offers improved performance characteristics such as faster switching speeds and lower power consumption. The 'STR' suffix indicates the tape and reel packaging format suitable for automated surface-mount assembly.

Latches Replacement Considerations

Check for direct pin-to-pin replacements within the same 74V family or other manufacturers offering equivalent single D-latch functionality in SOT23-5L packages. Verify that any substitute maintains the same voltage tolerance and propagation delay specifications.
