74VHC573MTC

Latches Overview

The onsemi 74VHC573MTC is an octal D-type latch featuring three-state outputs, housed in a TSSOP-20 package. It operates within a supply voltage range of 2 V to 3.6 V and supports a wide operating temperature from -40°C to +85°C. The device exhibits propagation delays of 4.9 ns at 2.7 V and 4.4 ns at 3.3 V. It provides high-level output current of -32 mA with a maximum power supply current of 5 mA.

Latches Feature Summary

• Provides eight non-inverting D-type latches with transparent data capture when the latch enable is active.
• Features three-state outputs that isolate the latch data from downstream circuitry when disabled.
• Designed for low-voltage operation compatible with 2 V to 3.6 V power domains.

Latches Applications

• Data bus buffering and storage in portable electronic devices
• I/O port expansion for microcontroller systems
• Register files in low-power digital logic circuits

Latches Procurement Notes

Verify the specific suffix 'MTC' confirms the TSSOP-20 surface-mount package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the design accounts for the specified 5 mA maximum power supply current during peak switching operations to maintain signal integrity.

Latches Selection Notes

Select this component for applications requiring octal latching with three-state control in compact surface-mount designs. Compare against HC or HCT series variants if higher drive current or different voltage compatibility is required. Verify that the 4.4 ns propagation delay meets the timing constraints of the target system clock speed.
