SN74AS575NT

Flip Flops Overview

The SN74AS575NT is an octal bus driver manufactured by Texas Instruments, belonging to the AS logic series. It features eight D-type latches with three-state outputs and a low-level enable control. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum load capacitance of 50 pF. It provides a maximum output current of 48 mA in the low state. The component is housed in a 24-pin PDIP package with a length of 31.64 mm and functions within a temperature range up to 70 °C.

Flip Flops Feature Summary

• Octal configuration providing eight independent data paths for high-density bus interfacing.
• Three-state outputs allow direct connection to system buses without additional buffering.
• Low-level enable control facilitates precise timing management for data latching operations.

Flip Flops Applications

• High-speed data bus architectures requiring parallel data transfer.
• Memory mapping circuits utilizing latch-based address or data storage.
• I/O port expansion systems needing tri-state isolation capabilities.

Flip Flops Procurement Notes

Verify the specific manufacturer designation on the component marking, as Rochester Electronics may distribute this part originally designed by Texas Instruments. Confirm that the physical package matches the 24-pin PDIP specification and check for any lead-free compliance markings if required by environmental standards. Ensure the enable pin logic level aligns with the low-active requirement specified in the datasheet.

Flip Flops Selection Notes

Select this component when designing systems that require octal latching with bus isolation capabilities. The AS series offers faster propagation delays compared to standard LS logic, making it suitable for higher frequency applications. Consider the 48 mA sink capability for driving moderate loads directly. Verify that the operating temperature range meets the specific environmental constraints of the target application.

Flip Flops Part Context

This part belongs to the SN74AS family of advanced Schottky logic devices, known for improved speed-power product over previous generations. The SN74AS575 variant specifically implements octal D-latch functionality with tri-state outputs. It serves as a critical interface element between microprocessors and peripheral devices in complex digital systems.
