Texas Instruments SN75451BP Dual Peripheral Driver DIP8

The Texas Instruments SN75451BP is a dual peripheral driver designed for use in systems that employ TTL logic. This device is functionally interchangeable with and replaces the SN75450 and SN75450A families, delivering equivalent speed while ensuring freedom from latch-up. Diode-clamped inputs simplify circuit design, and the output of the logic gates is internally connected to the bases of the npn output transistors, making it ideal for high-current switching at very high speeds.

Key Features

• Characterized for use to 300mA
• High-voltage outputs (up to 30V)
• No output latch-up at 20V (after conducting 300mA)
• High-speed switching
• TTL-compatible diode-clamped inputs
• Standard supply voltages (4.75V to 5.25V)
• Dual outputs for versatile applications

Applications

Typical applications include high-speed logic buffers, power drivers, relay drivers, lamp drivers, MOS drivers, line drivers, and memory drivers. The device is suitable for use in power management, lighting, and computer peripherals, providing circuit flexibility for varied applications.
