M74HC573TTR

Latches Overview

The M74HC573TTR is an octal D-type transparent latch with 3-state outputs manufactured by STMicroelectronics. It belongs to the HC logic series and operates within a supply voltage range of 2 V to 6 V. The device features low input current of 1.0 uA and high noise immunity typical of CMOS technology. It is housed in a TSSOP-20 surface-mount package and supports an operating temperature range from -55 °C to +125 °C. The component is designed for bus-oriented applications and includes a common output enable input.

Latches Feature Summary

• Octal D-type transparent latch functionality allowing data transparency when enabled
• Three-state non-inverting outputs suitable for bus-oriented applications
• High noise resistance characteristics inherent to silicon-gate CMOS technology
• Compatible with standard CMOS, NMOS, and TTL interfaces

Latches Applications

• Buffer registers for data storage and isolation
• I/O port expansion for microprocessor systems
• Bidirectional bus drivers for system interconnects
• Work registers in digital control circuits

Latches Procurement Notes

Verify the specific ordering suffix and package variant against the official STMicroelectronics datasheet to ensure compatibility with your design requirements. Confirm that the M74HC573TTR meets all necessary environmental and electrical specifications for your target application before finalizing procurement decisions.

Latches Selection Notes

Select this component for designs requiring octal latching with three-state bus control. Ensure the operating voltage aligns with the 2 V to 6 V range. Consider the TSSOP-20 package constraints and thermal performance within the specified temperature range during PCB layout and system integration planning.

Latches Part Context

This part is part of the M74HC573 family of octal D-type latches. It shares functional similarities with other industry-standard devices like the 74HC573 but is specifically manufactured by STMicroelectronics. The TTR suffix indicates the tape and reel packaging format, distinguishing it from cut-tape or tube variants.

Latches Replacement Considerations

Direct substitutes include generic 74HC573 equivalents from manufacturers such as NXP or Nexperia. Verify pinout compatibility and electrical parameters before substitution.
