Octal Non-Inverting D-Type Flip-Flops With 3-State Outputs
The RCA-CD54/74AC564 and CD54 74AC574 and the CD54/74ACT564 and CD54 74ACT574 octal D-type, 3-state, positive-edge-triggered Flip-Flops use the RCA ADVANCED CMOS technology. The eight Flip-Flops enter data into their Registers on the LOW-to-HIGH transition of the Clock (CP). The Output Enable (OE) controls the 3-state outputs and is independent of the Register operation. When the Output Enable (OE) is HIGH, the outpus are in the high-impendance state. The CD54/74AC/ACT564 and CD54/74AC/ACT574 share the same pin configurations; the CD54/74AC/ACT564, however, has inverted outputs and the CD54/74AC/ACT574 has non-inverted outputs.
The CD74AC/ACT564 and CD74AC/ACT574 are supplied in 20-lead dual-in-line plastic packages (E suffix) and in 20-lead dual-in-line small-outline plastic pakcages (M suffix). Both package types are operable over the following temperature range: Commercial (0- to 70C); Industrial (-40 to +85C); and Extended Industrial/Military (-55 to +125C).
The CD54AC/ACT564 and CD54AC/ACT574, available in chip form (H suffix), are operable over the -55 to +125C temperature range.
