DM74ALS175SJ

Overview

The DM74ALS175SJ is a D-type flip-flop integrated circuit belonging to the onsemi 74ALS logic family. It features four positive-edge-triggered D flip-flops with complementary outputs in a single circuit configuration. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 50 MHz. Propagation delay is specified at 17 ns under standard conditions (5 V, 50 pF load). It utilizes a 16-SOP surface-mount package and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Contains four independent positive-edge-triggered D-type flip-flops
• Provides both true and inverted outputs for each flip-flop stage
• Supports high-speed digital data storage applications up to 50 MHz
• Compatible with standard 5V CMOS/TTL logic levels

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Digital state storage elements in control systems
• Timing synchronization and pulse stretching

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability from secondary markets. Confirm RoHS compliance status as manufacturing processes may vary by production batch. Ensure proper ESD handling protocols are followed during installation given the sensitivity of ALS logic inputs. Validate package marking against official datasheet specifications to prevent counterfeit substitution.

Selection Notes

Select this component when designing systems requiring compact 4-bit storage with complementary output availability. Consider the 17 ns propagation delay for timing budget calculations in high-speed interfaces. Evaluate thermal management requirements for SOP-16 packaging in enclosed environments. Compare against SN74ALS175 variants if pin-compatible alternatives from other manufacturers are preferred for supply chain diversification.

Part Context

This part belongs to the 74ALS (Advanced Low-power Schottky) logic family, known for improved speed over standard 74LS devices while maintaining lower power consumption than 74AS series. The DM prefix indicates onsemi's specific manufacturing designation for this commercial-grade variant. It serves as a fundamental building block for sequential logic design in industrial and consumer electronics.

Replacement Considerations

SN74ALS175NSR from Texas Instruments is documented as a direct substitute.
