Presettable synchronous 4-bit binary counter; asynchronous reset
6.
Functional description
[1]
* = the TC output is HIGH when CET is HIGH and the counter is at terminal count (HHHH)
H = HIGH voltage level
h = HIGH voltage level one set-up time prior to the LOW-to-HIGH clock transition
L = LOW voltage level
l = LOW voltage level one set-up time prior to the LOW-to-HIGH clock transition
q = lower case letters indicate the state of the referenced output one set-up time prior to the LOW-to-HIGH clock transition
X = don’t care
= LOW-to-HIGH clock transition
7.
Limiting values
[1]
The minimum input voltage ratings may be exceeded if the input current ratings are observed.
[2]
The output voltage ratings may be exceeded if the output current ratings are observed.
[3]
For SO16 packages: above 70
C the value of P
D derates linearly with 8 mW/K.
For (T)SSOP16 packages: above 60
C the value of P
D derates linearly with 5.5 mW/K.
For DHVQFN16 packages: above 60
C the value of P
D derates linearly with 4.5 mW/K.
