74LCX573FT(AE)

Latches Overview

The Toshiba Semiconductor and Storage 74LCX573FT(AE) is a low-voltage octal D-type latch featuring 5-V tolerant inputs and outputs. It operates within a supply voltage range of 1.65 V to 3.6 V, designed for high-speed performance in 3.3-V systems while maintaining low power dissipation. The device includes eight data inputs, latch enable (LE), output enable (OE), and tri-state outputs. It provides power-down protection on all pins and maintains pin and function compatibility with the 74LVC/ALVC series 573 type.

Latches Feature Summary

• Low-voltage operation supporting 1.65 V to 3.6 V supply ranges
• High-speed operation achieving propagation delays as low as 8.0 ns at 3.0 V to 3.6 V
• Strong drive capability with minimum output currents of ±24 mA
• Power-down protection provided on all inputs and outputs

Latches Applications

• Data storage in 3.3-V digital systems
• Interfacing between 3.3-V logic and 5-V environments
• Octal bus latching applications requiring tri-state control

Latches Procurement Notes

Verify the specific ordering suffix AE against the manufacturer's current documentation to confirm package variant and tape/reel specifications. Confirm RoHS compliance status directly with Toshiba Semiconductor and Storage prior to procurement. Ensure design reviews account for the absolute maximum ratings regarding supply voltage and output current limits to prevent device deterioration.

Latches Selection Notes

Select this component when an octal latch with 5-V tolerance is required for low-voltage CMOS designs. It serves as a direct functional replacement for 74LVC/ALVC 573 types in mixed-voltage systems. Consider the TSSOP20B package dimensions and thermal characteristics during PCB layout. Verify that the application does not exceed the specified operating temperature range of -40°C to 85°C.

Latches Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic integrated circuits manufactured by Toshiba Semiconductor and Storage. The LCX series is engineered for high-speed operation combined with low static power consumption. The 573 designation specifically identifies the octal D-type latch configuration with transparent mode and tri-state outputs, widely used in memory address latching and data buffering.

Latches Replacement Considerations

Direct substitutes include other manufacturers' 74LCX573 variants in compatible packages. Verify electrical parameters such as propagation delay and output current capabilities match system requirements. Check for pinout compatibility with existing board layouts if replacing with non-Toshiba equivalents.
