SN75452BP-P

Buffers, Drivers, Receivers, Transceivers Overview

The SN75452BP is a dual peripheral driver from the SNx545xB family, designed for high-current and high-speed switching applications in systems employing TTL logic. It features NAND logic inputs with open-collector outputs capable of driving loads up to 300 mA. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports output voltages up to 30 V without latch-up after conducting rated current. Packaged in an 8-pin PDIP format, it functions as a replacement for older SN75450 series devices while maintaining equivalent speed characteristics.
