74ACT11373NS

Overview

The Texas Instruments 74ACT11373NS is an octal transparent D-type latch featuring three-state outputs, housed in a 24-pin SOIC package. It operates within a supply voltage range of 4.5 V to 5.5 V. The device exhibits a propagation delay of 10.3 ns at 5 V and draws a static current of 8 µA. Output drive capabilities include a low-level output current of 32 mA and a high-level output current of -24 mA. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Octal transparent D-type latch architecture with eight independent data channels
• Three-state outputs enabling direct bus driving connections
• Non-inverting logic polarity for straightforward signal path integration

Applications

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

Procurement Notes

Verify the specific suffix 'NS' corresponds to the 24-SOIC bulk packaging configuration rather than tape-and-reel variants like 'DWR'. Confirm RoHS compliance status matches current manufacturing standards. Ensure the supplier provides official datasheets referencing the SN74ACT11373 family specifications for accurate electrical parameter validation before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring parallel data latching with bus-compatible outputs. The ACT series offers speed comparable to LS logic with CMOS power efficiency. Verify that the 24-pin SOIC footprint aligns with the target PCB layout constraints. Ensure the application voltage remains strictly within the 4.5 V to 5.5 V operational window to maintain timing integrity.

Part Context

This part belongs to the Texas Instruments 74ACT logic family, which bridges the performance gap between standard TTL and advanced CMOS technologies. The 74ACT11373 specifically addresses applications needing high-speed data retention with minimal power consumption. It serves as a critical interface element in microprocessor-based systems for managing parallel data streams efficiently.

Replacement Considerations

The SN74ACT11373NS is the manufacturer's full designation for this component. Cross-reference with other 74ACT octal latch variants only if pin compatibility and electrical characteristics match exactly. Avoid substituting with non-three-state versions unless the bus isolation requirement is removed.
