SN74ALS640B-1DW TI Bus Transceiver | 20-SOIC | 8-Bit, Inverting, 3-State

Product Overview

The SN74ALS640B-1DW is a high-performance 8-bit bus transceiver from Texas Instruments, designed for bidirectional asynchronous communication between data buses. It features inverting outputs and 3-state outputs for bus-oriented applications. Housed in a 20-pin SOIC package, this device operates with a typical propagation delay of 6 ns and a wide supply voltage range of 4.5 V to 5.5 V. It is ideal for driving heavy capacitive loads and is compatible with TTL logic levels.
