SN74LS75D

Latches Overview

The SN74LS75D is a dual high-level triggered D latch from the Texas Instruments LS logic series. It features complementary Q and Q outputs for each of its two independent latches. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum load capacitance of 15 pF. It is housed in a 16-pin PDSO (SOIC-16) package with a plastic/epoxy body. The component functions as temporary storage for binary information, transferring data from input to output when the enable signal is high.

Latches Feature Summary

• Provides dual independent bistable latching circuits with complementary outputs
• Transfers data to the output state only while the enable signal remains high
• Retains stored information at the output when the enable signal transitions low

Latches Applications

• Temporary storage of binary information between processing units and I/O interfaces
• Data buffering in digital indicator systems
• Latching operations in MSI logic circuits

Latches Procurement Notes

Verify that the specific order matches the SOIC-16 surface mount package configuration. Confirm the manufacturer designation aligns with Texas Instruments or authorized production sources, as some listings may reference Motorola variants. Ensure compliance requirements are checked against the specific revision, noting potential non-RoHS status for certain manufacturing batches.

Latches Selection Notes

Select this component when dual independent latching with complementary outputs is required in a compact surface mount format. It is suitable for applications needing high-level triggered data retention rather than edge-triggered flip-flops. Consider the LS series propagation characteristics and power consumption profile relative to other logic families available in the same package footprint.

Latches Part Context

This part belongs to the standard 74LS TTL logic family, designed for medium-speed digital applications. It serves as a fundamental building block for sequential logic circuits requiring simple data storage capabilities. The dual-latch architecture allows for efficient handling of paired data lines within integrated circuit designs.
