74ACT11373NSR

Overview

The Texas Instruments 74ACT11373NSR is an octal transparent D-type latch with 3-state outputs, housed in a 24-pin SO (NS) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40°C to 85°C. The device features buffered input and output-enable pins, ensuring TTL-voltage compatibility. Key electrical characteristics include high-level output currents up to -24 mA and low-level output currents up to 24 mA. Propagation delays from data inputs to outputs range from 1.5 ns to 11.8 ns depending on conditions.

Feature Summary

• Features eight transparent D-type latches designed for full parallel access loading.
• Provides 3-state bus driving true outputs suitable for highly-capacitive or low-impedance loads.
• Utilizes buffered input and output-enable pins to minimize loading effects.
• Incorporates center-pin VCC and GND configurations to reduce high-speed switching noise.

Applications

• Implementing buffer registers
• Configuring I/O ports
• Serving as bidirectional bus drivers
• Functioning as working registers

Procurement Notes

Verify the specific ordering suffix 'NSR' corresponds to the standard plastic small-outline package variant. Confirm that the component meets RoHS compliance standards as indicated by the manufacturer's production data. Ensure the procurement channel provides valid traceability documentation for the electronic component. Cross-reference the datasheet revision date against the manufacturing lot code to ensure specification alignment.

Selection Notes

Select this component when designing systems requiring octal data storage with tri-state bus interfacing capabilities. It is appropriate for applications needing TTL-compatible inputs and robust drive strength for bus lines. Consider the 24-pin SO package dimensions for PCB layout constraints. Evaluate the propagation delay specifications against system timing requirements to ensure signal integrity during data transfer operations.

Part Context

This part belongs to the 74ACT logic family, utilizing EPIC (Enhanced-Performance Implanted CMOS) technology. It serves as a digital storage element within broader logic IC portfolios. The device complements other bus interface components by providing reliable data latching with high-impedance output states for efficient bus management in complex digital circuits.

Replacement Considerations

Check for direct pin-compatible alternatives within the same logic family. Verify if updated revisions of the 74ACT11373 series offer improved performance metrics. Ensure any substitute maintains the 3-state output functionality and compatible package footprint for seamless integration into existing designs.
