CD74ACT540

具有三态输出的八路反向缓冲器/线路驱动器

The CD54/74AC540, –541, and CD54/74ACT540, –541 octal buffer/line drivers use the RCA ADVANCED CMOS technology. The CD54/74AC/ACT540 are inverting 3-state buffers having two active-LOW output enables. The CD54/74AC/ACT541 are non-inverting 3-state buffers having two active-LOW output enables.

The CD74AC540, –541, and , –541 are supplied in 20-lead dual-in-line plastic packages E suffix and in 20-lead dual-in-line small-outline plastic packages M suffix. Both package types are operable over the following temperature ranges: Industrial –40 to +85°C and Extended Industrial/Military –55 to +125°C.

The CD54AC540, –541, and CD54ACT540, –541, available in chip form H suffix, are operable over the –55 to +125°C temperature range.
