SEMICONDUCTOR TECHNICAL DATA  
High–Performance Silicon–Gate CMOS  
N SUFFIX  
PLASTIC PACKAGE  
CASE 646–06  
14  
The MC74HC280 is identical in pinout to the LS280. The device inputs are  
compatible with standard CMOS outputs; with pullup resistors, they are  
compatible with LSTTL outputs.  
1
This circuit consists of 9 data–bit inputs (A through I) and 2 outputs (Even  
Parity and Odd Parity) to allow both odd and even parity applications. Words  
greater than 9–bits can be accommodated by cascading other HC280  
devices.  
D SUFFIX  
SOIC PACKAGE  
CASE 751A–03  
14  
1
This device can be used in systems utilizing the LS180 parity generator/  
checker. Although the HC280 does not have expander inputs, the  
corresponding function is provided by an input at pin 4 and the absence of  
any connection at pin 3. This permits the HC280 to be substituted for the  
LS180 to produce a similar function, even if the HC280s are mixed with  
existing LS180s. NOTE: Pullup resistors must be used on the LS180 outputs  
to interface with the HC280.
