CD74ACT373EG4

Latches Overview

The CD74ACT373EG4 is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the 74ACT logic series. It features eight independent latches with three-state outputs housed in a 20-pin PDIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 10.4 ns at 5 V. It provides a low-level output current of 32 mA and a high-level output current of -24 mA. The component functions reliably across an extended industrial temperature range from -55°C to +125°C.

Latches Feature Summary

• Octal transparent latch architecture providing eight independent data storage elements
• Three-state outputs enabling direct bus-organized system interfacing
• Extended industrial operating temperature range for harsh environments

Latches Applications

• Bus-oriented memory mapping systems
• Register file implementations in digital circuits
• Data buffering for parallel-to-serial conversion interfaces

Latches Procurement Notes

Verify the specific EG4 suffix against current manufacturer documentation to confirm lead wire material and RoHS compliance status. Confirm availability as this part may be discontinued or superseded by updated variants. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the Texas Instruments manufacturing lot.

Latches Selection Notes

Select this component when designing systems requiring wide temperature tolerance and high drive capability within the ACT logic family. Verify that the 4.5 V to 5.5 V supply requirement aligns with the target power rails. Consider the PDIP-20 through-hole package constraints if board space allows, ensuring compatibility with existing assembly equipment and manual soldering processes.

Latches Part Context

This device belongs to the Texas Instruments 74ACT series, which offers performance comparable to Low-power Schottky TTL but with CMOS power consumption characteristics. The CD74 prefix indicates commercial grade processing, while the ACT designation specifies the advanced technology node. This series is designed for high-speed applications requiring robust noise immunity and fast switching speeds.

Latches Replacement Considerations

CD74ACT373E is a confirmed substitute part number.
