SN75451B Datasheet | Texas Instruments

Features - 1 Characterized for Use to 300 m A - High-Voltage Outputs up to 30 V - No Output Latch-Up at 20 V (After Conducting 300 m A) - High-Speed Switching - Open-Collector Outputs - Circuit Flexibility for Varied Applications - TTL-patible Diode-Clamped Inputs - Standard Supply Voltages 2 Applications - High-Speed Logic Buffers - Power Drivers - Lamp Drivers - LED Drivers - Line Drivers - Memory Drivers 3 Description The SN5545x B and SN7545x B devices are dualperipheral drivers designed for use in systems that employ TTL logic. This family is functionally interchangeable with and replaces the SN75450 family and the SN75450A family devices manufactured previously. The speed of the devices is equal to that of the SN75450 family, and the parts are designed to ensure freedom from latch-up. Diodeclamped inputs simplify circuit design. The SNx5451B, SNx5452B, SNx5453B, and SNx5454B devices are dual peripheral AND, NAND, OR, and NOR drivers, respectively (assuming positive logic), with the output of the logic gates internally connected to the bases of the npn output transistors. The SN5545x B drivers are characterized for operation over the full military range of - 55°C to 125°C. The SN7545x B drivers are characterized for operation from 0°C to 70°C.
