The 74VHC273 is a Octal D-Type Flip-Flop The VHC273 is an advanced high speed CMOS OctalD-type flip-flop fabricated with silicon gate CMOS technology.It achieves the high speed operation similar toequivalent Bipolar Schottky TTL while maintaining theCMOS low power dissipation. The register has a common buffered Clock (CP) which isfully edge-triggered. The state of each D input, one setuptime before the LOW-to-HIGH clock transition, is transferredto the corresponding flip-flop's Q output. TheMaster Reset (MR) input will clear all flip-flops simultaneously.All outputs will be forced LOW independently ofClock or Data inputs by a LOW voltage level on the MRinput. An input protection circuit insures that 0V to 7V can beapplied to the inputs pins without regard to the supplyvoltage. This device can be used to interface 5V to 3Vsystems and two supply systems such as batterybackup. This circuit prevents device destruction due tomismatched supply and input voltages.
High Speed: fMAX = 165MHz (typ) at VCC = 5V
Low power dissipation: ICC = 4µA (max) at TA = 25°C
