Pin Descriptions  
LIST-XL Family  
PIN DESCRIPTIONS  
All signals are implemented in CMOS technology with TTL levels. Signal names that start with a slash (“/”) are active LOW.  
Inputs should never be left floating. The CAM architecture draws large currents during compare operations, mandating the  
use of good layout and bypassing techniques. Refer to the Electrical Characteristics section for more information.  
/E (Chip Enable, Input, TTL)  
/FF (Full Flag, Output, TTL)

off the DQ pins and clocks the Destination and Source  
Segment counters. The four cycle types enabled by /E are  
shown in Table 2 on page 2.  
The/FFoutputgoesLOWwhennoemptymemorylocations  
exist within the device.  
/RESET (Reset, Input, TTL)  
/RESET must be driven LOW to place the device in aknown  
state before operation, which will reset the device to the  
conditionsshowninTable4onpage8.The/RESETpinshould  
be driven by TTL levels, not directly by an RC time-out. /E  
must be kept HIGH during /RESET.  
/W (Write Enable, Input, TTL)  
The/Winputselectsthedirectionofdataflowduringadevice  
cycle. /W LOW selects a Write cycle and /W HIGH selects  
a Read cycle.

are at 0 Volts (system reference potential), for correct  
operation of the device. All the ground and power pins must

device.  
/CM (DATA/Command Select, Input, TTL)  
The /CM input selects whether the input signals on DQ15-0  
are data or commands. /CM LOW selects Command cycles  
and /CM HIGH selects Data cycles.  
/DQ15-0 (Data Bus, I/O, TTL)  
The DQ15-0 lines convey data, commands, and status to and  
from the LIST-XL. /W and /CM controls the direction and  
nature of the information that flows to or from the  
device.When /E is HIGH, DQ15-0 go to Hi-Z.  
/MF (Match Flag, Output, TTL)  
The /MF output goes LOW when one or more valid matches  
occur during the current or most recent compare cycle. /MF  
isHIGHifthereisnomatch./MFwillberesetwhentheactive  
configuration register set is changed.  
/MM (Device Multiple Match Flag, Output, TTL)  
The /MM output is LOW when more than one valid match  
occurs during the current or the most recent compare cycle.  
/MM will be reset when the active register set is changed.
