DS75452N

Overview

The DS75452N is a dual peripheral driver from the DS7545X series, designed for TTL logic systems. It implements a dual NAND gate function with outputs internally connected to NPN transistors. The device operates at standard supply voltages of 4.75V to 5.25V and supports an operating temperature range of 0°C to +70°C. It provides a 300mA output current capability and features high voltage outputs up to 30V without latch-up. Propagation delays are typically 26ns (low-to-high) and 24ns (high-to-low). Inputs are TTL compatible and diode-clamped.

Feature Summary

• Dual NAND logic function with internal connection to NPN output transistors
• High-speed switching with TTL-compatible diode-clamped inputs
• Capable of driving loads up to 30V without output latch-up

Applications

• High speed logic buffers
• Relay drivers
• Lamp drivers
• MOS drivers
• Bus drivers and memory drivers

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the Dual-In-Line (DIP-8) format. Ensure the ordering suffix corresponds to the plastic DIP variant. Validate RoHS compliance status as required by project specifications before finalizing procurement orders.

Selection Notes

Select this part when a dual NAND peripheral driver is required for TTL-based systems. It replaces older TI 'A' and 'B' series devices. Consider the 300mA output current and 30V output voltage limits during circuit design. Verify that the 0°C to +70°C operating temperature range meets environmental requirements.

Part Context

The DS75452N belongs to the DS75451/2/3 series of dual peripheral drivers originally developed by National Semiconductor and now managed by Texas Instruments. This family includes AND (DS75451), NAND (DS75452), and NOR (DS75453) variants. The series is designed to replace legacy TI 'A' and 'B' series components in existing designs.
