MC74LCX574 Low−Voltage CMOS Octal D−Type Flip−Flop Flow Through Pinout With 5 V−Tolerant Inputs and Outputs (3−State, Non−Inverting) The MC74LCX574 is a high performance, non−inverting octal D−type flip−flop operating from a 2.3 to 3.6 V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5 V allows MC74LCX574 inputs to be safely driven from 5.0 V devices. The MC74LCX574 consists of 8 edge−triggered flip−flops with individual D−type inputs and 3−state true outputs. The buffered clock and buffered Output Enable (OE) are common to all flip−flops. The eight flip−flops will store the state of individual D inputs that meet the setup and hold time requirements on the LOW−to−HIGH Clock (CP) transition. With the OE LOW, the contents of the eight flip−flops are available at the outputs. When the OE is HIGH, the outputs go to the high impedance state. The OE input level does not affect the operation of the flip−flops. The LCX574 flow through design facilitates easy PC board layout. http://onsemi.com MARKING DIAGRAMS 20 20 1 SOIC−20 DW SUFFIX CASE 751D LCX574 AWLYYWW 1 20 20 1 LCX 574 ALYW TSSOP−20 DT SUFFIX CASE 948E 1 Features • • • • • • • • • • • Designed for 2.3 to 3.6 V VCC Operation 5 V Tolerant − Interface Capability With 5 V TTL Logic Supports Live Insertion and Withdrawal IOFF Specification Guarantees High Impedance When VCC = 0 V LVTTL Compatible LVCMOS Compatible 24mA Balanced Output Sink and Source Capability Near Zero Static Supply Current in All Three Logic States (10 A) Substantially Reduces System Power Requirements Latchup Performance Exceeds 500 mA ESD Performance: Human Body Model >2000 V Machine Model >200 V Pb−Free Packages are Available* 20 20 1 SOEIAJ−20 M SUFFIX CASE 967 1 A L, WL Y, YY W, WW = = = = 74LCX574 AWLYWW Assembly Location Wafer Lot Year Work Week ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 3 of this data sheet. *For additional information on our Pb−Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D.
