DESCRIPTION
The 74F189A is a high speed, 64-bit RAM organized as a 16-word
by 4-bit array. Address inputs are buffered to minimize loading and
are fully decoded on chip. The outputs are in high impedance state
whenever the chip enable (CE) is high. The outputs are active only
in the READ mode (WE = high) and the output data is the
complement of the stored data.

NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.
2. All typical values are at V
CC
= 5V, T
amb
= 25°C.
3. Not more than one output should be shorted at a time. For testing I
OS
, the use of high-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, I
OS
tests should be performed last.
