SN54LS75J

Latches Overview

The SN54LS75J is a military-grade quad bistable latch utilizing Low-Power Schottky (LS) technology. It features four independent transparent D-type latches with complementary outputs, designed for temporary binary information storage between processing and I/O units. The device operates within a supply voltage range of 4.75V to 5.25V and supports an extended temperature range from -55°C to 125°C. Key electrical specifications include a maximum propagation delay of 19ns at nominal voltage, a maximum output low current of 8mA, and a maximum static power supply current of 12mA.

Latches Feature Summary

• Provides four independent bistable latches with complementary Q and Q-bar outputs for data retention
• Utilizes Low-Power Schottky technology to maintain TTL-compatible speeds while reducing power consumption
• Features input diode clamping to suppress transmission line effects such as ringing during high-speed switching

Latches Applications

• Military and defense applications requiring QML certification
• Temporary storage of binary information in processing units
• Data buffering between input/output units and logic circuits

Latches Procurement Notes

Verify the specific ordering suffix 'J' corresponds to the Ceramic Dual In-Line Package (CDIP) variant. Confirm that the component meets the required Military/Defense application standards associated with the SN54 series designation. Ensure compatibility with the specified 16-pin package dimensions and lead finish options before finalizing procurement orders.

Latches Selection Notes

Select this component when military-grade reliability and extended temperature operation are mandatory requirements. The SN54LS75J is appropriate for designs needing Low-Power Schottky performance characteristics combined with the robustness of ceramic packaging. Consider alternative catalog versions if commercial temperature ranges suffice.

Latches Part Context

This part belongs to the Texas Instruments SN54LS75 family of 4-bit bistable latches. The SN54 series denotes military qualification, distinguishing it from the commercial SN74LS75 variants. The device is manufactured using Low-Power Schottky technology, ensuring compatibility with standard TTL logic levels while offering improved power efficiency compared to earlier LS implementations.
