74ACT373MTCX

Latches Overview

The onsemi 74ACT373MTCX is an octal transparent latch with 3-STATE outputs, manufactured by Fairchild Semiconductor and distributed by onsemi. It operates within a supply voltage range of 4.5V to 5.5V. The device features TTL-compatible inputs and provides high drive capability with outputs sourcing and sinking 24 mA. Propagation delays are specified at 8 ns typical at 5.0V. It is housed in a 20-Lead Thin Shrink Small Outline Package (TSSOP).

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 provide high drive capability, capable of sourcing and sinking 24 mA.
• Latch Enable (LE) controls data transparency; Output Enable (OE) controls output state.

Latches Applications

• Bus organized system applications requiring data storage and buffering.
• Interfaces between TTL logic and AC/ACT logic families.
• Data acquisition systems utilizing transparent latch functionality.

Latches Procurement Notes

Verify the manufacturer origin, as this component was originally produced by Fairchild Semiconductor before being acquired by onsemi. Confirm the package type matches the required 20-Lead TSSOP footprint. Ensure the operating voltage requirements align with the 4.5V to 5.5V specification. Check for any specific lifecycle status updates regarding availability from current distributors.

Latches Selection Notes

Select this component when a wide supply voltage range compatible with 5V logic is required alongside high drive strength. The ACT series offers faster propagation speeds compared to standard AC devices while maintaining compatibility. Consider the TSSOP package if space constraints necessitate a smaller surface-mount footprint compared to SOIC or PDIP options.

Latches Part Context

This part belongs to the 74AC/ACT logic family, designed for high-speed digital applications. The 74ACT373 specifically targets systems needing robust bus driving capabilities. It serves as a bridge between older TTL standards and newer CMOS technologies, providing reliable data latching in complex digital circuits.

Latches Replacement Considerations

Direct substitutes include MC74ACT373DTR2G from onsemi and SN74ACT373PW or SN74ACT373PWR from Texas Instruments. These alternatives offer identical pinouts and electrical characteristics suitable for drop-in replacements in existing designs.
