74ACT11373NT

Overview

The Texas Instruments 74ACT11373NT is an octal transparent D-type latch with three-state outputs, housed in a 24-pin Plastic Dual-In-Line (PDIP) 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 are specified with maximum values of 11.8 ns for data-to-output transitions and 13 ns for latch-enable to output transitions.

Feature Summary

• Features eight transparent D-type latches with three-state outputs designed for driving highly-capacitive or low-impedance loads.
• Includes buffered latch-enable and output-enable inputs to control data storage and bus isolation without affecting internal operations.
• Utilizes center-pin VCC and GND configurations to minimize high-speed switching noise during operation.

Applications

• Implementing buffer registers
• Configuring I/O ports
• Driving bidirectional buses
• Serving as working registers

Procurement Notes

Verify the specific ordering suffix 'NT' corresponds to the standard plastic 300-mil PDIP package containing 24 pins. Confirm that the component status is listed as active for new designs. Ensure the procurement documentation matches the EPIC CMOS process specifications and RoHS compliance details provided in the manufacturer's package option addendum.

Selection Notes

Select this component when an octal latch with three-state capability is required for bus-oriented systems. The ACT series provides TTL-compatible inputs while maintaining CMOS performance levels. Consider the PDIP package constraints if through-hole mounting is necessary for the target application environment.

Part Context

This device belongs to the 74ACT logic family, utilizing Enhanced-Performance Implanted CMOS technology. It is part of a broader line of octal latches available in various packages, including SSOP, SOIC, and DIP formats. The 74ACT11373 serves as a foundational digital storage element for parallel data handling in industrial and commercial electronic circuits.

Replacement Considerations

Direct replacements include other variants of the 74ACT11373 such as the DBR (SSOP), DWR (SOIC), and NSR (SO) packages. Verify pinout compatibility and ensure the substitute maintains the same 24-pin configuration and electrical specifications.
