General Description
The VHC273 is an advanced high speed CMOS Octal
D-type flip-flop fabricated with silicon gate CMOS tech-
nology. It achieves the high speed operation similar to
equivalent Bipolar Schottky TTL while maintaining the
CMOS low power dissipation.
The register has a common buffered Clock (CP) which is
fully edge-triggered. The state of each D input, one setup
time before the LOW-to-HIGH clock transition, is trans-
ferred to the corresponding flip-flop's Q output. The
Master Reset (MR) input will clear all flip-flops simulta-
neously. 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
voltage. This device can be used to interface 5V to 3V
systems and two supply systems such as battery
backup. This circuit prevents device destruction due to
mismatched supply and input voltages.
Ordering Information
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the
ordering number. Pb-Free package per JEDEC J-STD-020B.
