PI74LPT373AS

Latches Overview

The PI74LPT373AS is an 8-bit transparent latch manufactured by Diodes Incorporated using advanced 0.6 micron CMOS technology. It features 3-state outputs and operates within a supply voltage range of 2.7V to 3.6V. The device supports mixed 3.3V/5.0V systems, allowing inputs to be driven from either voltage level. Key electrical parameters include a propagation delay (Dx to Ox) of up to 8.0ns for the standard grade, balanced output drive capabilities of 24mA sink and source, and an operating temperature range of -40°C to +85°C. It is available in 20-pin packages including TSSOP, QSOP, TQSOP, and SOIC.

Latches Feature Summary

• Supports 5V tolerant mixed signal mode operation with inputs accepting 3V or 5V levels
• Features hysteresis on all inputs to improve noise immunity
• Provides excellent output drive capability with balanced 24mA sink and source currents
• Designed for bus-oriented applications with low ground bounce outputs

Latches Applications

• Bus oriented data storage applications
• Mixed 3.3V/5.0V system translation
• Industrial control systems requiring wide temperature operation

Latches Procurement Notes

Verify the specific suffix 'AS' against the manufacturer's official documentation to confirm package type and tape/reel specifications. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing process. Ensure the ordering information matches the exact logic family and speed grade required for your design.

Latches Selection Notes

Select this component when an 8-bit transparent latch with 3-state outputs is required for bus applications. It is suitable for designs needing compatibility with LCX and LVT families. Consider the specific speed grade (A vs C) based on maximum allowable propagation delay. Verify package availability in TSSOP, QSOP, TQSOP, or SOIC formats to match PCB layout constraints.

Latches Part Context

This part belongs to the PI74LPT series of fast CMOS logic circuits produced by Pericom Semiconductor Corporation, now part of Diodes Incorporated. The LPT series is characterized by advanced 0.6 micron CMOS technology, offering industry-leading speed grades while maintaining low power consumption. These devices are designed for high-performance digital applications requiring reliable data latching and bus driving capabilities.

Latches Replacement Considerations

The datasheet notes compatibility with LCX and LVT families. Verify pinout and electrical characteristics before substituting with generic 74LVC or 74LVX equivalents. Check if alternative parts support the same 5V tolerant input requirements and 3-state output functionality.
