74ACT11373DWR

Overview

The SN74ACT11373DWR is an octal transparent D-type latch manufactured by Texas Instruments. It features eight independent D-type latches with three-state outputs, housed in a 24-pin SOIC package. The device operates within a supply voltage range of 4.5V to 5.5V and supports propagation delays of 8.5ns. It provides high-drive outputs capable of sourcing and sinking 24mA, ensuring robust signal integrity in digital logic applications across industrial temperature ranges.

Feature Summary

• Octal configuration providing eight independent transparent D-type latches for parallel data storage
• Three-state outputs allowing direct connection to bus structures without external drivers
• High-drive output capability supporting significant load currents for reliable signal transmission

Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register implementations
• Clock domain crossing synchronization buffers

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 24-SOIC footprint matches the target PCB design constraints. Ensure the operating temperature range aligns with the environmental specifications of the final electronic system integration.

Selection Notes

Select this component when designing systems requiring multiple simultaneous data latching operations with bus-compatible outputs. The ACT series offers faster switching speeds compared to standard TTL equivalents while maintaining compatible logic levels. Evaluate power consumption requirements against the specified static current characteristics for low-power design optimization.

Part Context

This part belongs to the Texas Instruments 74ACT logic family, which combines the speed of advanced TTL technology with CMOS low-power characteristics. The 74ACT11373 variant specifically addresses applications needing wide data path storage. It serves as a critical interface element between microprocessors and peripheral devices in complex digital architectures.
