74LCX273  
Low-Voltage Octal D Flip-Flop  
with 5V Tolerant Inputs and Outputs  
General Description  
Features  
Y
5V tolerant inputs and outputs  
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.

Power-down high impedance inputs and outputs  
Supports live insertion/withdrawal  
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.

Implements patented Quiet SeriesTM noise/EMI  
reduction circuitry  
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.

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.
