3. Specifications. 

DIGITAL INPUT SPECIFICATIONS 

On-state voltage range 

2 to 5V DC 

Maximum off-state voltaje 

0.8V 

Maximum operation frequency 

4 MHz 

Typical signal delay 

10nS 

 

DIGITAL OUTPUT SPECIFICATIONS 

Maximum output voltage  

(5V power supply voltage) + 0.5V 

Typical output current  

24mA 

Maximum off-state voltaje 

0.44 V 

Maximum operation frequency 

4 MHz 

Typical signal delay 

10 nS 

Time of transition to high impedance state 

12 nS* 

*Time passed since a low in the ENABLE input is detected and the outputs are disabled 

Requirements: 

It requires a 5VDC @ 1000 milliamps power supply to operate.  

 

 

WARNING

 

Check  the  polarity  and  voltage  of  the  external  power  source  and  connect  the  5V 
and  GND.      Overvoltage  or  reverse-polarity  power  applied  to  these  terminals  can 
cause damage to the board, and/or the power source.
