74HC273; 74HCT273  
Octal D-type flip-flop with reset; positive-edge trigger  
Rev. 03 — 24 January 2006  
Product data sheet  
1. General description  
The 74HC273; 74HCT273 is a high-speed Si-gate CMOS device and is pin compatible  
with Low-power Schottky TTL (LSTTL).  
The 74HC273; 74HCT273 has eight edge-triggered, D-type flip-flops with individual  
D inputs and Q outputs. The common clock (pin CP) and master reset (pin MR) inputs  
load and reset (clear) all flip-flops simultaneously. The state of each D input, one set-up  
time before the LOW-to-HIGH clock transition, is transferred to the corresponding output  
(Qn) of the flip-flop.  
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.  
2. Features  
Ideal buffer for MOS microprocessor or memory  
Common clock and master reset  
Eight positive edge-triggered D-type flip-flops  
Complies with JEDEC standard no. 7A  
ESD protection:  
HBM EIA/JESD22-A114-C exceeds 2000 V
