74F525 General Description


The 'F525 is a multi-function 28-pin device. It consists of a 16-bit count-down counter, logic to control the counter, logic to control the state of the outputs and a PLA to decode the particular function selected by the user. The list of highspeed timing applications include:

74F525 Maximum Ratings

Storage Temperature ...............................-65 to +150
Ambient Temperature under Bias .............-55 to +125
Junction Temperature under Bias .............-55 to +175
Plastic .......................................................-55 to +150
VCC Pin Potential to
Ground Pin .................................................-0.5V to +7.0V
Input Voltage (Note 2) ...............................-0.5V to +7.0V
Input Current (Note 2) .........................-30 mA to +5.0 mA
Voltage Applied to Output
in HIGH State (with VCC e 0V)
Standard Output ...........................................-0.5V to VCC
TRI-STATE® Output ....................................-0.5V to +5.5V
Current Applied to Output
in LOW State (Max) twice the rated IOL (mA)
Note 1: Absolute maximum ratings are values beyond which the device may be damaged or have its useful life impaired. Functional operation under these conditions is not implied.
Note 2: Either voltage limit or current limit is sufficient to protect inputs.
