Octal Non-Inverting D-Type Flip-Flops with 3-State Outputs - CD74AC574
Datasheet
 

Description

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 70°C); Industrial (-40 to +85°C); and Extended Industrial/Military (-55 to +125°C).

The CD54AC/ACT564 and CD54AC/ACT574, available in chip form (H suffix), are operable over the -55 to +125°C temperature range.
