74ACT11373DBR

Overview

The Texas Instruments 74ACT11373DBR is an octal transparent D-type latch featuring three-state outputs, housed in a 24-pin SSOP package. It operates within a supply voltage range of 4.5V to 5.5V and supports a propagation delay of 8.5ns. The device provides high drive capability with output currents of 24mA for both high and low states. Designed for surface-mount installation, it functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Octal transparent D-type latch architecture with eight independent data paths
• Three-state outputs enabling direct bus-driven connections without external buffers
• High-current drive capability supporting 24mA source and sink loads
• Industrial-grade operational stability across extended temperature variations

Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register storage
• Temporary data holding in digital signal processing systems

Procurement Notes

Verify the specific ordering suffix 'DBR' confirms the tape-and-reel packaging format and 24-SSOP component variant. Ensure compatibility with standard 5V logic levels and confirm that the specified propagation delay meets system timing requirements. Cross-reference the manufacturer part number against official datasheets to validate pinout configurations and electrical characteristics before integration.

Selection Notes

Select this component when designing systems requiring parallel data latching with bus-compatible outputs. The ACT series offers faster switching speeds compared to legacy counterparts while maintaining CMOS power efficiency. Consider the 24-SSOP footprint for space-constrained printed circuit board layouts requiring surface-mount assembly techniques.

Part Context

This device belongs to the Texas Instruments 74ACT logic family, which combines the speed of bipolar technology with the low power consumption of CMOS processes. The 74ACT11373 specifically addresses applications needing octal data storage with tri-state control, serving as a fundamental building block for complex digital interfaces and memory subsystems.

Replacement Considerations

Direct functional equivalents include the SN74ACT11373DWR in SOIC-24 packaging or the SN74ACT11373N in DIP-20 configuration. Verify pin compatibility and electrical specifications when substituting with other octal latch variants from different manufacturers.
