They possess the low power consumption of standard CMOS integrated circuits. Information at the D inputis transferred to the Q outputs 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. All eight Q outputs are reset to a logic 0. Pinout CD54HC273, CD54HCT273, CD74HC273, CD74HCT273 (PDIP, SOIC, CERDIP) TOP VIEW Ordering Information PART NUMBER TEMP. RANGE (oC) PACKAGE PKG. NO.
