MC74ACT373DWG

Latches Overview

The MC74ACT373DWG is an octal transparent latch with 3-state outputs manufactured by onsemi. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. The device contains eight D-type latches in a single package, providing bus-organized system applications. Propagation delay from data input to output is typically 8.5 ns at 5.0 V. Maximum quiescent supply current is 80 µA at 5.5 V. Outputs can source or sink up to 24 mA. The component is housed in a SOIC-20W package (Case 751D) and supports surface mount installation.

Latches Feature Summary

• Contains eight D-type latches with 3-state standard outputs for bus interfacing
• Features TTL compatible inputs for the ACT series
• Outputs are capable of sourcing and sinking 24 mA

Latches Applications

• Bus organized system applications
• Data storage and buffering
• Interface between logic circuits and buses

Latches Procurement Notes

Verify the specific ordering suffix 'DWG' corresponds to the SOIC-20W package and Pb-Free status as documented in the manufacturer's ordering information table. Confirm that the lead marking matches the specified format for this variant. Ensure compliance with moisture sensitivity level requirements during handling and storage prior to soldering.

Latches Selection Notes

Select this component when designing systems requiring octal latching with high drive capability and 3-state control. The ACT series provides TTL-compatible input thresholds suitable for 5 V logic interfaces. Consider the propagation delay characteristics and output current capabilities relative to the load requirements of the target application circuit.

Latches Part Context

This part belongs to the MC74AC/ACT373 family of octal transparent latches. It shares functional similarities with other devices in the 74ACT logic series but is distinguished by its specific pinout, package type, and electrical characteristics defined by the ACT series specifications. It serves as a digital storage element in complex logic designs.
