74LVC374A Low-Voltage CMOS Octal D-Type Flip-Flop With 5 V-Tolerant Inputs and Outputs (3-State, Non-Inverting) www.onsemi.com The 74LVC374A is a high performance, non-inverting octal D-type flip-flop operating from a 1.2 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 74LVC374A inputs to be safely driven from 5 V devices. The 74LVC374A 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. * * Designed for 1.2 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 24 mA Output Sink and Source Capability Near Zero Static Supply Current in All Three Logic States (10 mA) Substantially Reduces System Power Requirements ESD Performance: Human Body Model >2000 V Machine Model >200 V These are Pb-Free Devices (c) Semiconductor Components Industries, LLC, 2016 April, 2016 - Rev. 2 20 LVC 374A ALYWG G TSSOP-20 DT SUFFIX CASE 948E 20 1 1 A L, WL Y, YY W, WW G or G = Assembly Location = Wafer Lot = Year = Work Week = Pb-Free Package (Note: Microdot may be in either location) Features * * * * * * MARKING DIAGRAM 1 ORDERING INFORMATION See detailed ordering and shipping information on page 8 of this data sheet.
