SN74HCT540DW TI Buffer/Driver | 20-SOIC | 8-Ch, Inverting, 5V

Product Overview

The SN74HCT540DW from Texas Instruments is a high-performance octal buffer and line driver designed for 5V CMOS logic systems. It features inverting outputs with 3-state capability, making it ideal for bus-oriented applications. Housed in a 20-pin SOIC package, this device offers a balance of speed, power efficiency, and noise immunity. It is compatible with TTL logic levels and can drive up to 15 LSTTL loads. The SN74HCT540DW is part of the HCT family, which combines the low power of CMOS with the speed of TTL.
