Data sheet acquired from Harris Semiconductor SCHS249B CD54AC273, CD74AC273 CD54ACT273, CD74ACT273 Octal D Flip-Flop with Reset August 1998 - Revised July 2002 Features Description • Buffered Inputs The ’AC273 and ’ACT273 devices are octal D-type flip-flops with reset that utilize advanced CMOS logic technology. Information at the D input is transferred to the Q output on the positive-going edge of the clock pulse. All eight flip-flops are controlled by a common clock (CP) and a common reset (MR). Resetting is accomplished by a low voltage level independent of the clock. • Typical Propagation Delay - 6.5ns at VCC = 5V, TA = 25oC, CL = 50pF • Exceeds 2kV ESD Protection MIL-STD-883, Method 3015 • SCR-Latchup-Resistant CMOS Process and Circuit Design Ordering Information • Speed of Bipolar FAST™/AS/S with Significantly Reduced Power Consumption PART NUMBER • Balanced Propagation Delays • AC Types Feature 1.5V to 5.5V Operation and Balanced Noise Immunity at 30% of the Supply • ±24mA Output Drive Current - Fanout to 15 FAST™ ICs - Drives 50Ω Transmission Lines Pinout CD54AC273, CD54ACT273 (CDIP) CD74AC273, CD74ACT273 (PDIP, SOIC) TOP VIEW TEMPERATURE RANGE PACKAGE CD74AC273E 0oC to 70oC -40oC to 85oC -55oC to 125oC 20 Ld PDIP CD54AC273F3A -55oC to 125oC 20 Ld CDIP CD74ACT273E 0oC to 70oC -40oC to 85oC -55oC to 125oC 20 Ld PDIP CD54ACT273F3A -55oC to 125oC 20 Ld CDIP CD74AC273M 0oC to 70oC -40oC to 85oC -55oC to 125oC 20 Ld SOIC CD74ACT273M 0oC to 70oC -40oC to 85oC -55oC to 125oC 20 Ld SOIC NOTES: MR 1 20 VCC Q0 2 19 Q7 D0 3 18 D7 D1 4 17 D6 Q1 5 16 Q6 Q2 6 15 Q5 D2 7 14 D5 D3 8 13 D4 Q3 9 12 Q4 GND 10 11 CP 1.

Addendum-Page 1 PACKAGE OPTION ADDENDUM www.ti.com 6-Dec-2006 (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
