SN74ACT573N

Overview

The SN74ACT573N is an octal D-type transparent latch with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and accepts input voltages up to 5.5V, ensuring TTL-voltage compatibility. The device features a maximum propagation delay of 9.5ns at 5V. It is designed for driving highly capacitive or low-impedance loads and is housed in a 20-pin PDIP package.

Feature Summary

Features three-state outputs suitable for driving high-capacitance or low-impedance loads
Provides TTL-voltage compatible inputs accepting voltages up to 5.5V
Operates as an octal D-type transparent latch with buffered output enable

Applications

Parallel data storage
Digital bus buffer
Buffer registers
I/O ports
Working registers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm active production status and lead finish specifications. Ensure the selected variant matches the required operating temperature range and packaging format for the intended application design.

Selection Notes

Select this component when designing systems requiring octal latching with high-speed performance and strong drive capabilities. The ACT series offers faster switching speeds compared to standard HC logic while maintaining CMOS power efficiency. Verify that the system load does not exceed the continuous output current ratings specified in the electrical characteristics table.

Part Context

This part belongs to the SNx4ACT573 family of octal D-type transparent latches with three-state outputs. The family includes military-grade (SN54ACT573) and automotive-qualified (SN74ACT573-Q1) variants alongside the catalog SN74ACT573 series. All variants share identical logical functionality but differ in qualification standards and environmental ratings.

Replacement Considerations

Direct functional equivalents include other SN74ACT573 variants such as SN74ACT573DWR or SN74ACT573DBR. Cross-manufacturer replacements like MC74ACT573DWR2G are listed as similar alternatives.
