1 / 15 page 1 Data sheet acquired from Harris Semiconductor SCHS249B Features • Buffered Inputs • Typical Propagation Delay - 6.5ns at VCC = 5V, TA = 25 oC, C L = 50pF • Exceeds 2kV ESD Protection MIL-STD-883, Method 3015 • SCR-Latchup-Resistant CMOS Process and Circuit Design • Speed of Bipolar FAST™/AS/S with Significantly Reduced Power Consumption • 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 50 Ω Transmission Lines Pinout CD54AC273, CD54ACT273 (CDIP) CD74AC273, CD74ACT273 (PDIP, SOIC) TOP VIEW Description 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. 11 12 13 14 15 16 17 18 20 19 10 9 8 7 6 5 4 3 2 1 MR Q0 D0 D1 Q1 Q2 D3 D2 Q3 GND VCC D7 D6 Q6 Q7 Q5 D5 D4 Q4 CP Ordering Information PART NUMBER 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: 1.
