DS75451M

Overview

The DS75451M is a dual peripheral driver from the DS7545X series, designed for TTL logic systems. It implements a dual AND gate function with outputs internally connected to NPN transistors. The device supports a supply voltage of 4.75V to 5.25V and operates within a temperature range of 0°C to +70°C. It features a 300mA output current capability and high-voltage outputs up to 30V without latch-up at 20V. Propagation delays are typically 25ns (low-to-high) and 25ns (high-to-low). Inputs are diode-clamped for TTL compatibility.

Feature Summary

• Dual AND logic function with internal connection to NPN output transistors
• High-speed switching with 300mA output current capability
• TTL compatible diode-clamped inputs
• No output latch-up at 20V

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm datasheet revision SNOSBM3A matches the supplied documentation. Ensure the package type corresponds to the SO-8 molded configuration. Check RoHS compliance status as original National Semiconductor products may vary in lead content specifications.

Selection Notes

Select this component when a dual AND gate peripheral driver is required for TTL-based designs. Verify that the 300mA sink current meets load requirements. Consider thermal derating constraints for the SO package if simultaneous high-current operation is expected. Ensure input signals remain within the specified 5.5V maximum limit.

Part Context

This part belongs to the DS75451/2/3 series of dual peripheral drivers originally developed by National Semiconductor and now managed by Texas Instruments. The 'M' suffix indicates an SOIC-8 plastic surface-mount package. It serves as a replacement for earlier TI 'A' and 'B' series devices while maintaining functional compatibility.
