DS75453M

Overview

The DS75453M is a dual peripheral driver from the DS7545X series, designed for TTL logic systems. It implements a NOR gate function with outputs internally connected to NPN transistor bases. The device supports a supply voltage range of 4.75V to 5.25V and operates within a temperature range of 0°C to +70°C. It provides a 300mA output current capability and features high-voltage outputs rated up to 30V without latch-up at 20V. Propagation delays are typically 18ns (low-to-high) and 16ns (high-to-low). Inputs are TTL compatible with diode clamping.

Feature Summary

• NOR logic function implementation
• High-speed switching performance
• TTL-compatible diode-clamped inputs

Applications

• High speed logic buffers
• Relay drivers
• Lamp drivers
• Bus drivers

Procurement Notes

Verify the manufacturer origin, as National Semiconductor was acquired by Texas Instruments. Confirm the package type matches the 'M' suffix designation. Ensure the component meets RoHS requirements if applicable to the specific production batch. Check for obsolescence status before finalizing procurement plans.

Selection Notes

Select this component when a NOR logic function is required alongside high-current driving capabilities. It serves as a direct replacement for older TI 'A' and 'B' series devices. Consider the SOIC package constraints regarding power dissipation derating above 25°C during thermal design.

Part Context

This part belongs to the DS75451/2/3 series of dual peripheral drivers. The 'M' suffix indicates an SOIC package variant, distinct from the DIP 'N' version. The series covers AND, NAND, and NOR functions, providing versatile options for peripheral interface designs requiring robust output stages.
