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.
