74LVTH573MTC

Latches Overview

The Fairchild Semiconductor 74LVTH573MTC is an octal transparent latch featuring three-state outputs, manufactured using advanced BiCMOS technology. It operates within a voltage range of 2.7 V to 3.6 V and supports 5-V tolerant inputs. The device provides high drive capability with output currents of -32 mA (source) and 64 mA (sink). Propagation delays are specified at 4.9 ns at 2.7 V and 4.4 ns at 3.3 V. It is housed in a TSSOP-20 package and functions as a non-inverting logic element.

Latches Feature Summary

• Advanced BiCMOS construction for high-speed operation combined with low power consumption
• Integrated bus-hold circuitry eliminates the need for external pull-up resistors
• Supports hot-insertion capabilities while maintaining high impedance during power transitions

Latches Applications

• Bus-oriented memory and register implementations
• Clock buffers and drivers
• Sampling registers in data acquisition systems

Latches Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official documentation. Check for End-of-Life notices or production discontinuation alerts from the manufacturer. Validate package markings against datasheet specifications to prevent counterfeit infiltration.

Latches Selection Notes

Select this component for designs requiring 3.3 V logic levels with 5 V input tolerance. The integrated bus-hold feature simplifies PCB layout by removing external components. Ensure supply chain availability given potential lifecycle restrictions associated with legacy BiCMOS logic families.

Latches Part Context

This part belongs to the LVTH series of low-voltage TTL-compatible logic devices. It serves as a standard octal latch solution for embedded systems transitioning from 5 V to 3.3 V architectures. The TSSOP-20 package offers a compact surface-mount footprint suitable for dense board layouts.

Latches Replacement Considerations

Consider the 74LVTH573MTCX variant for reel-based manufacturing processes. Verify pinout compatibility when substituting with other LVTH series latches.
