MC74ACT373DTR2G

Latches Overview

The MC74ACT373DTR2G 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. Key electrical parameters include a propagation delay of 10 ns at 5 V, a maximum quiescent supply current of 80 µA, and output drive capabilities sourcing -24 mA and sinking 24 mA. It is housed in a TSSOP-20 package.

Latches Feature Summary

• Contains eight D-type latches with 3-state standard outputs for bus interfacing
• Features TTL-compatible inputs for direct interface with TTL logic systems
• Outputs are capable of sourcing and sinking 24 mA
• Latch Enable (LE) controls data transparency while Output Enable (OE) manages high impedance states

Latches Applications

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

Latches Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the TSSOP-20 package and 'R2G' indicates tape and reel packaging as documented in the manufacturer's ordering information. Confirm RoHS compliance and lead-free status through official material composition documents. Ensure the component matches the exact part number MC74ACT373DTR2G to guarantee correct logic family and pinout compatibility.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs and TTL-compatible input thresholds is required. The ACT series ensures compatibility with standard TTL logic levels while offering improved speed over older families. Consider the TSSOP-20 package dimensions and thermal characteristics for PCB layout. Verify that the operating temperature range of -40°C to +85°C meets the environmental requirements of the target application.

Latches Part Context

This component belongs to the MC74AC/ACT373 family of octal transparent latches. The 'ACT' designation signifies CMOS technology with TTL-compatible inputs, distinguishing it from the standard AC series which has different input voltage thresholds. The device is designed for high-speed digital applications requiring multiple latched outputs with tri-state control capabilities.

Latches Replacement Considerations

MC74ACT373DWG is a direct replacement in SOIC-20W packaging. SN74ACT373PW and SN74ACT373PWR from Texas Instruments are also listed as direct substitutes.
