description
This 16-bit address comparator simplifies
addressing of memory boards and/or other
peripheral devices. The four P inputs are normally
hardwired with a preprogrammed address. An
internal
decoder
determines
information applied to the A inputs must be low or
high to cause a low state at the Y output. For
example, a positive-logic bit combination of 0111
(decimal 7) at the P input determines that inputs
A1 through A7 must be low and that inputs A8
through A16 must be high to cause the output to
go low. Equality of the address applied at the
A inputs to the preprogrammed address is
indicated by the output being low.
what
input
This device features an enable (G) input. When G is low, the device is enabled. When G is high, the device is
disabled and the output is high, regardless of the A and P inputs.
The SN74ALS677A is characterized for operation from 0
°
C to 70
°
C.
