SN74LS75DR

Latches Overview

The SN74LS75DR is a quad bistable latch manufactured by Texas Instruments using Low-power Schottky (LS) technology. It features four independent transparent D-type latches, each providing complementary Q and Q outputs. The device operates within a supply voltage range of 4.75V to 5.25V and supports a propagation delay of up to 27ns at 5V with 15pF load. It utilizes standard TTL input logic levels and offers an output low-level current capability of 8mA. Designed for surface-mount applications, it is housed in a 16-pin SOIC package.

Latches Feature Summary

• Provides four independent transparent D-type latches with complementary outputs
• Utilizes Low-power Schottky technology for reduced power consumption while maintaining TTL-compatible speeds
• Features diode-clamped inputs to suppress transmission line effects such as ringing during high-speed switching

Latches Applications

• Temporary storage of binary information between processing units and I/O modules
• Data buffering where data must be held stable when clock edges are not ready
• General-purpose digital logic circuits requiring parallel data retention

Latches Procurement Notes

Verify the specific suffix 'DR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance standards applicable to your manufacturing region. Ensure the selected variant matches the necessary operating temperature range and electrical specifications defined in the official datasheet before finalizing procurement orders.

Latches Selection Notes

Select this component when designing systems requiring multiple independent latching channels within a single integrated circuit. It is suitable for applications needing transparent latch functionality rather than edge-triggered flip-flops. Consider the LS series characteristics for balancing speed requirements against power dissipation constraints in standard 5V logic environments.

Latches Part Context

This part belongs to the widely adopted 74LS logic family, known for its compatibility with standard Transistor-Transistor Logic (TTL) systems. The SN74LS75 series serves as a fundamental building block for sequential logic design, offering a cost-effective solution for basic data storage needs in industrial and consumer electronics applications utilizing legacy or mixed-signal architectures.

Latches Replacement Considerations

Compatible substitutes include other manufacturers' SN74LS75 variants in SOIC packages. Verify pinout compatibility and electrical parameter equivalence, specifically propagation delay and output drive strength, when cross-referencing with alternative suppliers.
