SN74ABTH245N TI Bus Transceiver | 20-PDIP | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74ABTH245N is a high-performance 8-bit bus transceiver from Texas Instruments, designed for bidirectional asynchronous communication between two data buses. It features non-inverting outputs and 3-state outputs for bus-oriented applications. Housed in a 20-pin PDIP package, this device operates from a 4.5V to 5.5V supply and supports mixed-voltage operation with 5V-tolerant inputs. The SN74ABTH245N is ideal for driving heavy capacitive loads and offers high drive capability of ±32 mA at the A port and ±64 mA at the B port. Its advanced BiCMOS technology ensures low power consumption while maintaining high speed.
