MC74AC373MELG

Latches Overview

The MC74AC373MELG is an octal transparent latch with 3-state outputs manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an operating temperature from -40°C to +85°C. The device features eight D-type latches in a single package, providing non-inverting data storage. Propagation delays are specified at 13.5 ns maximum at 3.3 V and 9.5 ns at 5.0 V. Quiescent supply current is typically 8 µA at 5.5 V. Outputs can source or sink up to 24 mA.

Latches Feature Summary

• Contains eight D-type latches with 3-state standard outputs for bus interfacing
• Outputs provide high impedance state when Output Enable (OE) is HIGH
• Latch Enable (LE) controls transparency of data inputs to outputs
• Pb-Free devices compliant with environmental standards

Latches Applications

• Bus organized system applications
• Data storage in digital circuits
• Interface between microprocessors and peripheral devices

Latches Procurement Notes

Verify the specific ordering suffix 'MELG' against official documentation, as it may indicate a specialized package or configuration not explicitly detailed in the standard datasheet table. Confirm moisture sensitivity level and packaging type directly with the manufacturer or authorized distributors to ensure compatibility with assembly processes.

Latches Selection Notes

Select this component for designs requiring multiple latched outputs with tri-state capability. Ensure the supply voltage falls within the 2.0 V to 6.0 V range. Consider propagation delay specifications relative to system clock speeds. Verify input voltage thresholds match the driving logic family.

Latches Part Context

This part belongs to the 74AC series of logic ICs, known for high-speed CMOS performance. It is functionally similar to other octal latches but distinguished by its specific output drive capabilities and 3-state control. The AC series offers improved speed over older HC/HCT counterparts while maintaining low power consumption.
