74VHC273 Octal D-Type Flip-Flop April 1994 Revised May 2003 74VHC273 Octal D-Type Flip-Flop General Description Features The VHC273 is an advanced high speed CMOS OctalHigh Speed: f = 165 MHz (typ) at V = 5V MAX CC D-type flip-flop fabricated with silicon gate CMOS technol- Low power dissipation: I = 4 μA (max) at T = 25°C CC A ogy. It achieves the high speed operation similar to equiva- High noise immunity: V = V = 28% V (min) lent Bipolar Schottky TTL while maintaining the CMOS low NIH NIL CC power dissipation.Power down protection is provided on all inputs The register has a common buffered Clock (CP) which isLow noise: V = 0.9V (max) OLP fully edge-triggered. The state of each D input, one setup Pin and function compatible with 74HC273 time before the LOW-to-HIGH clock transition, is trans- Leadless DQFN Package ferred to the corresponding flip-flop’s Q output. The Master Reset (MR) input will clear all flip-flops simultaneously. All outputs will be forced LOW independently of Clock or Data inputs by a LOW voltage level on the MR input. An input protection circuit insures that 0V to 7V can be applied to the inputs pins without regard to the supply volt- age. This device can be used to interface 5V to 3V systems and two supply systems such as battery backup. This cir- cuit prevents device destruction due to mismatched supply and input voltages.
