DS75452M

Overview

The DS75452M is a dual peripheral driver from the DS7545X series, designed for TTL logic systems. It implements a NAND logic function with outputs internally connected to NPN transistor bases. The device operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range of 0°C to +70°C. It provides a low-level output current capability of 300 mA and features TTL-compatible diode-clamped inputs. Propagation delay times are typically 35 ns for both low-to-high and high-to-low transitions under standard test conditions.

Feature Summary

• High-current output capability of 300 mA
• TTL compatible diode-clamped inputs
• NAND logic function implementation

Applications

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

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the SOIC-8 designation. Ensure compliance with RoHS directives if required by project standards. Review absolute maximum ratings before integration to prevent damage during operation.

Selection Notes

Select this component when a NAND logic function with high drive current is required in a TTL system. Verify that the 300 mA output current meets load requirements. Consider thermal dissipation limits for the specific package variant. Ensure input voltage levels remain within the specified 4.75V to 5.25V range for reliable switching performance.

Part Context

This device belongs to the DS75451/2/3 series of dual peripheral drivers originally developed by National Semiconductor and now managed by Texas Instruments. The series includes AND (DS75451), NAND (DS75452), and NOR (DS75453) variants. These devices replace earlier 'A' and 'B' series components while maintaining similar functional characteristics and pinouts.
