SN74LS375N

Latches Overview

The SN74LS375N is a D-type transparent latch from the LS series, manufactured by onsemi. It features two functional circuits within a single package, providing complementary outputs for each bit. The device operates with a supply voltage range of 4.75V to 5.25V and utilizes TTL logic levels. It is housed in a 16-pin Plastic Dual In-Line Package (PDIP) with a standard .3-inch width. The component supports high-level triggering mechanisms and is designed for applications requiring reliable data storage and transfer in digital systems.

Latches Feature Summary

• Transparent D-type latch architecture enabling direct data passage when enabled
• Dual independent functional circuits providing complementary output signals
• High-level triggered operation compatible with standard TTL logic families

Latches Applications

• Digital data storage and buffering in microprocessor interfaces
• Parallel-to-serial data conversion circuits
• Status register implementation in control systems

Latches Procurement Notes

Verify the specific manufacturer origin, as Texas Instruments and onsemi both produce this part number. Confirm RoHS compliance status, as older batches may not meet current environmental standards. Check for obsolete status indicators, as availability varies significantly between distributors. Ensure the PDIP-16 package matches your PCB footprint requirements before finalizing procurement decisions.

Latches Selection Notes

Select this component when dual-channel latching with complementary outputs is required in a compact DIP package. Consider the LS series speed and power consumption characteristics relative to system needs. Verify that the high-level trigger requirement aligns with the controlling logic signals. Evaluate the 16-pin form factor against available board space constraints.

Latches Part Context

This component belongs to the widely adopted 74LS logic family, known for balanced performance between speed and power dissipation. The SN74LS375N specifically addresses the need for dual-bit latching without consuming multiple IC slots. Its complementary output capability simplifies differential signaling designs common in legacy industrial equipment.

Latches Replacement Considerations

SN74LS375N is an alternative to DM74LS375N. Verify pin compatibility and electrical specifications before substitution.
