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 CD74ACT540, ?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.
