74LCX273
Low-Voltage Octal D Flip-Flop
with 5V Tolerant Inputs and Outputs
General Description
The LCX273 has eight edge-triggered D-type flip-flops with
individual D inputs and Q outputs. The common buffered
Clock (CP) and Master Reset (MR) input load and reset
(clear) all flip-flops simultaneously.
The register is fully edge-triggered. The state of each D in-
put, one setup time before the LOW-to-HIGH clock tran-
sition, is transferred to the corresponding flip-flop’s Q out-
put.
All outputs will be forced LOW independently of Clock or
Data inputs by a LOW voltage level on the MR input. The
device is useful for applications where the true output only is
required and the Clock and Master Reset are common to all
storage elements.
The device is designed for low voltage (3.3V) V
CC
applica-
tions with capability of interfacing to a 5V signal environ-
ment. The LCX273 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
